Water Tools
Purpose and Scope
The South Dakota Department of Agriculture and Natural Resources (DANR) has developed multiple GIS mapping viewers to promote transparency, support environmental monitoring, and give customers access to their resource management information. The Construction Aggregate Mining Map is one of these essential tools for managing and overseeing mining activities across South Dakota. A comprehensive and easy-to-use guide of the licensed sources of construction aggregate, both current (active) and historic (closed), this publication is an essential resource for researchers, policymakers, local communities, and industry professionals.
Aggregate, including sand, gravel, and crushed stone (other necessary materials to maintain South Dakota’s infrastructure), versus the Special Aggregates Department. It is used in building highways, roads, bridges, and other road construction projects. To responsibly manage these limited resources, the DANR issues mining permits and maintains a file of active and inactive sites in its central database. The Construction Aggregate and Mining Map serves as an interactive, publicly accessible platform for viewing these data geographically. It covers the entire state and details more than 500 active licenses, with nearly 1,400 pits covering around 20,000 acres and over 5,200 sites licensed since spring 1983. This historical level of detail is essential for stakeholders to identify overall trends in mining activities over the past 40 years and to evaluate the environmental and economic impacts of aggregate extraction.
Key Features of the Map
The Construction Aggregate and Mining Map combines GIS visualization with tabular data, allowing both external site analysis and querying to obtain more background information. Key Feature Site Information Access: Click on each mine site to view details such as the operator's name, facility address, county, material type (sand or gravel), site status (active or inactive), and specific location details, including township, section, and range. Base Map Choices: Multiple styles are available, including blueprint, charted territory, colored pencil, community map, and dark gray canvas. Switching basemaps provides additional context about transportation, neighborhoods, or natural features based on user needs. Legend and Symbolization: Map symbols include red dots indicating active aggregate sites, green dots representing reclaimed or inactive sites, and county polygons outlining jurisdictional boundaries. These visual cues aid both technical and nontechnical users. Attribute Table (Bottom, Interactive): The table at the bottom displays detailed information for each site, such as Operator Name, Address, City, County, State, Zip Code, Site Status, and Material Received. Databases can be exported for offline analysis to support research, reporting, and decision-making. For example, policymakers are interested in Brookings County activities, while researchers are tracking Morris Inc. or Homestake Mining Company. Another feature is the export tool, which allows users to download data sets directly. This makes it easier for researchers and planners to analyze aggregate data offline. This integration of spatial and attribute data helps prevent misidentification of a site. Filtering and Search Options: As expected, the filtering features are robust. Users can browse by site number or operator, or narrow results using filters such as county or license year. This enables users to focus on specific regions or operators.
Applications and Benefits
The Construction Aggregate and Mining Map has many applications across several industries:
Environmental Monitoring: Enables regulators to track the total and spatial extent of mining sites, facilitating the evaluation of impacts on land use, water quality, and aquatic ecosystems. Supervising not only active but also inactive sites helps maintain and manage reclaimed lands, ensuring they are suitable for other uses after reclamation. Policy and Planning: Local governments can utilize the map to assess resource abundance within their jurisdiction, which is crucial for infrastructure planning, zoning, and achieving a balanced approach between economic growth and environmental preservation. Public Transparency and Community Knowledge: Nearby communities can access information about mining operations in their area. Concerned residents can learn who operates the closest active sites and how they mitigate land disturbance, dust, or water impacts. Research and Studies: The comprehensive data set, spanning from 1983, provides a valuable resource for analyzing long-term patterns of resource extraction. Researchers can study spatial trends, compare activity over decades, and relate mining data to changes in demographics or the environment. Industry accountability promotes transparency within the mining sector, benefiting companies and ensuring that operators adhere to their license terms and practice responsibly.

The Dry Draw Location Notice Search is a web-based interactive mapping/database developed by the South Dakota Department of Agriculture and Natural Resources (DANR). It offers the public greater access to information about the dams and dugouts built in dry-draw watercourses. The app is an essential tool for DANR’s transparency, environmental tracking, and historical archive—regulatory enforcement and public knowledge.
A dry draw is that which South Dakota Codified Law (SDCL) 46-1-6(8) refers to as a drainageway in which water flows typically only during and following precipitation or snowmelt. Traditionally, these sites were used to construct small dams, dikes, or dugouts for livestock watering, irrigation, and erosion control. To control these structures, South Dakota statutes require landowners to file a “Location Notice” with the State Engineer’s Office, setting forth information such as ownership, drainage area, basin capacity, and a geographic description. Thousands of such notices have been posted throughout the state since 1939. The Dry Draw Location Notice Search application is an interactive, convenient, and easy-to-use digital tool for viewing these records.
The application consists of two main compartments: a search panel (on the left) and an interactive map viewer (on the right). The map is interactive and built on Esri’s ArcGIS platform, using a dataset that shows South Dakota’s geographical boundaries, allowing users to pan, zoom, and locate specific notice locations. The basemap layer is based on high-resolution imagery from Earthstar Geographics, Esri, HERE, Garmin, and others, so terrain and land use are depicted with great accuracy.
A search panel provides various filtering options to help users narrow down retrieved results. These include:
Township, Range, and Section (allows searches in PLSS); County, to show all location notices filed against a specific county; Owner, to locate notices filed by a particular person or business; Location Notice Number of records by location or find identifier; and Filed On and Before is used to sift notices out by their filing date.
When a search criterion is chosen, the map is refreshed with orange points for field location notices. Each dot represents an observed dry draw location. They can also zoom in to view specific items or click a point, which will open a pop-up window with information such as the owner’s name, date filed, legal land description, and direct links to documents and records. This user-friendly feature allows for rapid checking and spatial interpretation of water management information.
Below the map, a table shows all search results in tabular form—key fields store table key information. Location Notice Number (LN No.), Business or Owner Name, Date Received, County, Quarter-Section (Qsec), Section, Township, Range, and Range Direction (N/S or E/W), also AF value (acre-feet of storage).
There is also a link in each entry here to the source, which allows you access to the scanned PDF. These are PDFs of scanned versions of official filings dating back to the mid-20th century, often handwritten or typewritten. Each record includes the locator’s affidavit data, estimated drainage and basin dimensions, and notarization. Publication of these files in an accessible format will make the underlying data more transparent and maintain historical hydrological information.
The online map also features user-interface capabilities, such as the ability to pan and zoom the map on a sliding scale of distance or area, following where users want to check for notices, such as within a certain number of miles. This is significantly valuable for local studies or environmental impact evaluations. It is a tool available to hydrologists, ecological engineers, local government, and landowners that enables them to locate water structures, review legal filings, and help plan watershed management.
The Dry Draw Location Notice Search digitizes more than 50 years of location notice records, improving how South Dakota handles its water infrastructure data. It removes the need for manual archival searching and enables spatial analysis with other environmental datasets (e.g., soil maps, aquifer boundaries, and flood zones). The best also supports decisions on land development, agricultural planning, and water resource conservation, ensuring that projects adhere to environmental regulations and conserve sustainable resources.
Overall, the Dry Draw Location Notice Search provides an interface that combines historical records with contemporary GIS technology. It makes those static paper filings part of an interactive, spatially referenced digital system and a tool for enabling accessibility and efficiency. This application illustrates how the South Dakota DANR is using geospatial technologies to protect and manage waters, keep good environmental records, and involve the public in natural resource health.

Introduction
Developed by the South Dakota Department of Agriculture and Natural Resources (DANR), the Harmful Algal Blooms (HABs) Map is a key monitoring tool. It gives the public, water managers, and scientists near-real-time access to data on harmful algal blooms statewide. Toxic algal blooms are rapid expansions of cyanobacteria, also known as blue-green algae, that can produce toxins such as microcystins. These toxins pose a threat to aquatic ecosystems, human health, and the recreational use of lakes and reservoirs.
Our HABs Map combines data from field monitoring, toxin sampling, and official notifications into a single, interactive GIS-based platform. By showing where blooms are occurring and how toxin levels change, the dashboard increases transparency, facilitates research, and provides communities with the information they need to stay safe while using South Dakota’s waters.
Purpose and Context
South Dakota is increasingly concerned about cyanobacterial blooms, which are linked to nutrient enrichment, high summer temperatures, and stagnant water. When these blooms happen, they can release toxins that make people, livestock, and pets sick. One of the most common toxins found in South Dakota, microcystins, can damage the liver at high levels.
The HABs Map was created to serve multiple purposes:
- Public Awareness: Offer up-to-date information on the locations of toxic blooms and whether it's safe to recreate in those areas.
- Regulatory Support: Enable local governments and agencies to issue advisories or close off access to water bodies when toxin levels surpass safe thresholds.
- Research and Management: Provide scientists and watershed managers with historical and current data to help them understand bloom patterns and their drivers.
Dashboard Overview
When you open the HABs Map, you'll see a statewide view with monitoring sites marked by blue stars. Each star represents a location where we collect and analyze shoreline samples for cyanotoxins. The legend shows the toxin concentration ranges, from low levels (0–8 micrograms per liter) to extremely high levels above 1,000 micrograms per liter. This lets users quickly understand the relative severity of blooms immediately.
Another key feature is the use of red flag markers, which show official warnings about harmful algal blooms. These symbols point out water bodies with advisories, alerting swimmers, boaters, and anglers to potential health risks.
Interactive Features
The HABs dashboard provides several tools for exploration and analysis:
- Layer Panel: Users can switch between datasets for different years (2019–2023), including those for toxin-producing algae, shoreline microcystin monitoring, mid-lake sampling, and HAB notifications. This historical view is crucial for analyzing trends and pinpointing recurring issues.
- Attribute Tables: At the bottom of the screen, users can see detailed, tabular data tied to the map. The tables show waterbody names, sampling dates, toxin concentrations, and geographic coordinates. Users can filter, sort, or export columns to CSV for more in-depth statistical analysis.
- Pop-Up Details: Clicking a star or flag icon shows a detailed data panel for that monitoring site. Here, users can review toxin results from multiple sampling events, view graphs of microcystin concentration trends, and identify the exact location using latitude and longitude.
- Graphical Summaries: The dashboard shows charts that track microcystin concentrations over time, allowing managers to visualize bloom patterns throughout the summer season.
- Sharing Tools: Users can create links or share map updates straight to Facebook, LinkedIn, X (Twitter), or Bluesky, making it easier to reach a wider audience.
Data and Reports
The HABs Map integrates field data from the DANR monitoring network. Reports include:
- Shoreline Monitoring Data: Gathered near recreational areas to evaluate immediate risks to swimmers and boaters.
- Mid-Lake Monitoring Data: Offers more in-depth information for deep-water sites, where cyanobacteria may build up in different ways.
- Microcystin Concentration Records: Monitor microcystin levels over time, typically showing spikes after hot, calm weather or storm runoff.
- Official HAB Notifications: Emphasize cases where toxin levels exceeded thresholds, triggering local alerts.
For instance, in 2023, the map highlights notifications for Lake Mitchell, Lake Louise, Jones Lake, Lake Herman, and Lake Marindahl. Microcystin levels ranged significantly, from moderate detections at around nine micrograms per liter to extremely high results of over 17,000 micrograms per liter.
Professional Applications
The HABs Map serves multiple professional communities:
- Public health officials: use toxin data to evaluate risks, issue warnings, and prevent exposure to contaminated water by humans or animals.
- Water Resource Managers: Use past data to identify seasonal patterns, assess nutrient management strategies, and lower the frequency of blooms.
- Researchers: can use multi-year datasets to investigate the factors driving bloom formation, including land use, climate, and watershed characteristics.
- Local governments and communities: can use notifications to plan recreational access, protect tourism, and keep residents informed.
- Environmental and Agricultural Planners: Link bloom trends with patterns of nutrient runoff to inform long-term conservation planning.
Conclusion
South Dakota relies heavily on the Harmful Algal Blooms Map for decision-making and public outreach. This tool combines real-time data, historical records, and interactive GIS features to give a clear picture of water quality statewide. Its design enables the quick detection of active algal blooms, as well as the long-term examination of bloom patterns and risk factors.
For the public, the HABs Map offers straightforward and easily accessible information on water safety, protecting recreational users. For professionals, it provides a reliable data source for managing water quality, research, and policy development. As harmful algal blooms continue to pose a challenge to sustainable water resources, this dashboard will remain a vital tool for both immediate action and long-term planning.

The Measured Lake Elevations Map is an interactive tool that provides historical and current lake-elevation data for waterbodies across South Dakota via the South Dakota Department of Agriculture and Natural Resources (DANR) Data and Mapping Portal. Built from decades of elevation measurements, the system provides a user-friendly point-and-click interface for viewing changes in lake surface elevation. The public can utilize detailed maps to observe patterns in lake behavior and hydrological changes over time. When opening the app, users see a large statewide map with blue points, each representing a lake with collected elevation data over several years. The map is fully searchable and zoomable, and allows users to select a feature to view more details. Clicking on a point displays that lake’s measurement history. The right-hand panel offers valuable filtering options. The "Select Lake" filter enables users to narrow the list of lakes by name or county. This feature makes it easy to target specific waterbodies or compare local lakes. The "Clear Filters" button resets all filters, restoring the map to its full statewide view.
When a lake is clicked, the dashboard filters and displays more specific elevation data for that location. The lower part of the screen shows a full Measurement Table listing elevation measurements recorded by county, date, and key hydrologic calibration information, along with a Comment section — double asterisks indicate technical discussions from DANR. Some measurements date back to the 1970s or 1980s, providing a long-term series of water-level changes. An interactive elevation chart within the table illustrates how the lake's water level has changed over the years and decades. Users can hover over each point on the graph to see specific elevation and date details, helping them identify drought periods, flood years, steady increases or decreases in water level, and seasonal patterns. This visual aid helps put long-term hydrologic trends into perspective, especially when analyzing data spanning several decades. Clicking on a specific body of water, such as Fish Lake in Aurora County, loads the historical dataset for that area, allowing users to view detailed elevation changes. It also includes pop-up markers that display coordinates and the official lake name when a user clicks on the lake location.
The app also features a full-screen Lake Elevation by Year page, designed for those who prefer an uncluttered, maximized view of the time-series line chart. This view removes noise, making year-over-year changes easier to analyze. Looking at that table reveals the historical depth of DANR’s monitoring program. Data has been systematically collected over many years for lake measurements, offering valuable context for long-term watershed responses, climate trends, and lake stability. As lake elevations fluctuate due to precipitation, evaporation, drought cycles, runoff rates, and seasonal changes, these records are crucial for water management, hydrologic modeling, and environmental science.
The app also includes an informational section, such as the Historic Lake Level Data in South Dakota, which provides details on how lake levels are measured and read. DANR notes that most lakes are monitored twice a year in spring and fall. All measurements are referenced to the National Geodetic Vertical Datum of 1929 (NGVD29), ensuring consistency across lakes and over time. However, not all seasonal measurements correspond to a lake's nominal high or low water levels; they are initial elevations taken on specific days. The information panel also explains the Ordinary High-Water Mark, Ordinary Low-Water Mark, and Lake Outlet Elevation, established by the State Water Commission. These benchmarks are used to determine public use boundaries, lake management rules, and water rights. South Dakota: Waterways are considered public highways, and access is available within fifty feet on each side of a waterway from the edge of the bank. The informational sign notes that different rules govern some lakes with high-water marks set before 1985. In some cases, adjoining landowners may retain certain rights to use the water under this statute. The panel directs users to the Water Rights Program for questions about water marks, lake outlets, or property rights.
A final disclaimer notes that, although DANR is "making and publishing these measurements in good faith, it cannot guarantee the absolute accuracy" of all its historical records. Because some measurements were taken several decades ago, variations in equipment, seasonal differences, and recording practices may affect the interpretation of the data.
Overall, the Measured Lake Elevations Map offers an excellent mix of historical data, new visualization tools, and a regulatory perspective. By allowing users to easily review long-term water level records, compare trends across multiple lakes, and analyze hydrological behavior across the state, the system encourages data-driven water management and public understanding of lake dynamics. It also supports research, climate assessment, watershed evaluation, and helps communities, landowners, and policymakers make informed decisions. South Dakota One Call’s application demonstrates South Dakota's commitment to openness, transparency, and responsible environmental stewardship. For those interested in exploring this resource further, follow this link to the South Dakota DANR Data and Mapping Portal to find the Measured Lake Elevations application, which provides access to decades of hydrological history.

The Observation Wells Application, available through the South Dakota Department of Agriculture and Natural Resources (DANR) Data and Mapping Portal, offers a comprehensive and interactive platform for exploring groundwater conditions across the state. Designed for both professionals and the public, it provides real-time access to decades of groundwater measurement data collected from observation wells throughout South Dakota. When users open the app, they see a detailed satellite basemap with colorful markers. Each marker represents a specific observation well and is color-coded to indicate the monitoring route it belongs to, such as the Black Hills, Brookings, Pierre, Watertown routes, or other specialized monitoring areas. These routes help identify regional sampling networks and show how well distribution aligns with South Dakota’s hydrologic and geologic features.
The left side of the application features the central search panel. Here, users can refine their well search using parameters such as date, observation well number, section, township, range, county, or aquifer. The date filter allows users to review well with readings recorded before or after a specific date. At the same time, the text-based fields support land survey-style searches common in groundwater and cadastral mapping. Users can also combine multiple search conditions using “And” or “Or” logic, enabling detailed queries for specific environmental studies or reporting needs. A map-based search option adds another layer of functionality: by specifying a distance radius and enabling map-click mode, users can quickly identify wells within a selected distance of any point on the map. This feature is handy for evaluating wells near lakes, agricultural fields, development areas, or groundwater-dependent ecosystems.
When a search is performed, the map updates to highlight wells matching the criteria, and the bottom panel automatically switches to the Results tab. This panel displays a table of key well information, including the observation well ID, USGS ID, township-range-section data, aquifer type, casing elevation, total well depth, casing length, and seasonal monitoring assignment. From this results panel, users can directly access hydrographs, download data records, or open the whole well-specific information window. Clicking a well on the map opens a detailed pop-up with complete metadata, including the well’s alternate name, drilling details, surveyed coordinates, aquifer classification, regulatory comments, and elevation measurements referenced to the top of casing. Some wells include links to lithologic logs, which describe geologic materials encountered during drilling and are vital for understanding hydrogeologic behavior.
The hydrograph tool, available through the pop-up or the Hydrograph tab, is one of the most valuable analytical features of the system. Hydrographs display long-term groundwater level measurements for the chosen well, often spanning decades. Each plotted point represents a water level measurement taken during a site visit. These hydrographs show subtle, long-term changes in groundwater elevation caused by climate variability, seasonal recharge, droughts, floods, agricultural withdrawals, and regional aquifer characteristics. Users can hover over points to see precise measurement values and dates, providing detailed insight into groundwater fluctuations. The Hydrograph tab also presents the same data in a table, listing reading dates, elevations, latitude, longitude, and whether the reading was manually collected. This allows for easy examination of data trends and comparison of measurements across different years.
The Well Data tab expands the available information by providing detailed historical records for each observation well. These records assist researchers in monitoring groundwater behavior, evaluating aquifer health, understanding spatial differences among well clusters, and analyzing the impact of land use or regional climate patterns on groundwater conditions. The data also plays a vital role in water rights documentation, environmental permitting, hydrologic modeling, and long-term resource management. The availability of downloadable data promotes its use in external analysis tools such as GIS platforms, statistical software, or groundwater modeling applications.
On the right side of the application, users will find several map tools that enhance navigation and map-based analysis. Zoom-To tools allow quick switching between map views, while measurement tools help calculate area, distance, and coordinates in units such as acres, miles, or degrees. These tools are invaluable for field mapping, spatial planning, and verifying proximity to features such as rivers, lakes, sections, or county boundaries. The ability to click anywhere on the map to retrieve latitude and longitude further aids in precise location referencing and real-world site investigation.
Together, these components build an intuitive, scientifically sound system that connect users to South Dakota’s groundwater monitoring network. By offering open access to historical and current groundwater data, the Observation Wells Application improves public transparency, aids environmental research, and enhances water management and planning decisions. Whether used by hydrologists studying aquifer behavior, landowners monitoring nearby wells, policymakers assessing long-term water availability, or students learning about groundwater science, the application serves as a vital tool for understanding the complexities of South Dakota’s groundwater resources and the long-term patterns that influence them.

The South Dakota Department of Agriculture and Natural Resources (DANR) Data and Mapping Portal serves as a single access point for datasets, interactive GIS applications, and regulatory information from DANR. The Permitted Solid Waste Facilities Dashboard is one of the most informative and user-friendly resources on this portal. Its purpose is to enable users to explore where, what type, and how solid waste facilities permitted across South Dakota operate. It functions as a published, data-driven, interactive, shapefile-based statewide map that allows users to visually and quantitatively explore how different types of waste are managed, how facilities are distributed geographically across counties and cities, and how waste-related infrastructure is mapped across the state.
Upon loading the dashboard, users are immediately shown a map of South Dakota that is strangely detailed and full of colored dots. Each point on this map indicates a solid waste facility permitted to receive waste. The colors of these points are not chosen randomly; instead, they represent the types of waste the facility collects. The system features a variety of different facility types, including coal ash disposal sites, construction debris locations, kiln dust facilities, yard waste collection areas, medical waste processors, regional landfills, petroleum-contaminated soil handlers, restricted-use sites, waste tire systems, transfer stations, and multi-use operators. Facility types are color-coded, so immediately, you can see the different functions of the facilities, making it very easy and intuitive for even non-GIS users to understand.
In addition to visualization, the dashboard includes embedded tools for exploration and analysis. Users can buffer, search for places, and switch the basemap to a style of their choice. It features detailed satellite images, street maps, terrain maps, or a simple bright background with roads and landmarks—all in one application. These visualization tools are handy for studying terrain near a facility, evaluating nearby infrastructure, and analyzing land-use patterns in an area.
At the top of the website, there is a dashboard with robust filters that let you quickly narrow down facilities by city or county. Selecting a town limits the map to facilities within that city, while choosing a county does the same for all facilities in that county. This dynamic filtering feature allows local government officials, environmentalists, and community members to see what types of waste-management facilities are currently operating in their state. It also helps identify potential regional gaps, concentrations of similar facilities, or areas that may need additional resources.
The dashboard includes a category panel on the right side of the map, allowing you to select the types of facilities shown carefully. Users can toggle categories on and off to view only the facilities they are interested in. For instance, if you want to see just yard-waste sites or only regional landfills, you can turn off all other categories with a single click. When managing many categories—such as landfills versus restricted-use facilities—and comparing two or more, this panel provides layered views that are both selective and flexible. This makes the dashboard a powerful tool for visual analysis in environmental planning, waste-stream evaluation, and educational purposes.
Click on any point on the map to display an information box with a brief profile of the facility. This profile typically includes the facility type and waste category, the operating organization, contact name, mailing address, point-of-contact details, and specific sub-classifications relevant to that facility. Seventy-three facility entries also include notes or comments that provide context or operational information. At the top of the information window, a “Zoom To” feature allows users to easily zoom in and center on a selected facility for more detailed location information. This feature can be especially useful in rural areas or when comparing nearby facilities.
Information is provided for each facility, including who operates it, its category, and who can be contacted for official information. For example, if someone chooses a secure facility, they can learn the facility's operator, the county involved, and the names of several key employees. A coal ash facility might list the associated power company, and a yard-waste site may display operators by city. Multi-service sites show combined types (e.g., transfer station/petroleum-contaminated soil handling site), highlighting the full range of their capabilities.
Together, these features create a clear, user-friendly system for navigating the statewide network of approved WMPs. By providing access to both regulatory and operational information, the dashboard enhances the industry's environmental leadership by making it easier for residents, policymakers, researchers, and others interested in understanding how waste is managed in South Dakota. With visual and facility-specific details in one place, the app supports decision-making, environmental compliance, and public awareness. Society is a member-led organization, and the SD Wastewater Information System is a crucial digital resource aligned with South Dakota’s focus on fulfilling environmental health responsibilities and proper waste disposal. Citizens can search the dashboard in the South Dakota DANR Data and Mapping Portal, in the Waste Management Program section, to find all permitted solid waste facilities that are mapped and logged.

The map was developed as a GIS application to directly link individuals to legislation regarding illegal dumping and promote citizen awareness of how they can do their part in keeping the environment clean. This online tool offers residents, businesses, and community leaders access to a spatial depiction of recycling center activity via an interactive map interface that lets users search for nearby centers that accept recyclables in categories such as metals, plastics, paper, electronics, and cars. By incorporating Esri’s web mapping capabilities, the platform converts complex environmental data into an intuitive, user-friendly interface that supports both community engagement and sustainable development objectives.
When users open the dashboard, they can see a map of South Dakota, but instead of the usual red dots, green recycling icons appear. The sites are permitted to accumulate, decompose, or recycle recyclable and reusable materials under the state’s environmental regulations. The interface is simple, yet intuitive; users can zoom, pan, and click on a facility icon to view site-specific information. This visual shows the locations of recycling facilities across the state, in urban, rural, and industrial areas.
There are two tools on the left side of the app—Layers and Search. With the Layers feature, users can view State and Local Roads on the map, along with imagery or topographic layers to improve visualization and spatial understanding. Users can also refine their search by entering the Facility Name, City, County, or Accepted Material Type in the Search panel. This is especially useful for residents and communities seeking local recycling centers or agencies to which they can donate their waste materials. By simply entering search criteria, users can easily generate a list of nearby suitable waste treatment facilities, making it convenient and accessible.
For instance, selecting Brookings County automatically zooms the map to locations in and around Brookings. Among other features, this helps to prevent users from inadvertently leaving the area they are interested in. The interactive table below the map automatically refreshes with the name, address, and city for each facility, along with the materials they accept. The table can even be dynamically extended, sorted, or collapsed to complement your workspace and give you more room to focus on the information that matters. This function improves data clarity and comparison between different facilities.
Clicking any green icon opens a pop-up window with specific information for that site, including the facility name, location, phone number, and materials they accept. Among other examples, the Brookings City Landfill accepts yard and tree waste, white goods, and tires; Cook’s Wastepaper and Recycling processes aluminum cans, corrugated cardboard, and mixed paper. The Goodwill of the Great Plains transfer station accepts electronic waste (including computers, monitors, printers, and scanners). At the same time, Wes’s Auto Salvage is open for business, accepting vehicles or vehicle parts for processing into metal. Each record has a “Zoom to” option that automatically centers the map on the selected facility, facilitating navigation and closer spatial examination.
The map also has an interactive ‘results’ section that displays all facility details in the same view or allows users to hide results and see a cleaner map layout. The tool integrates contact details and an accepted materials list for each facility, and aims to inform householders, recycling companies, and disposal authorities. This option is advantageous for estimating the geographic distribution of recycling and for tracking collections to monitor diversion or recovery trends at the state level.
On a larger level, the map shows just where recycling facilities are located throughout South Dakota and highlights trends in our management of environmental resources. Facilities are concentrated in the largest cities—Rapid City, Brookings, and Sioux Falls—suggesting that urban and semi-urban areas serve as “material recovery” hubs. Population appears to be a factor, but also an aspect of infrastructure (i.e., the location of transportation routes and the organization of garbage collection). And the less common distributed locations in western and rural areas also suggest a potential need to expand recycling access and improve waste management networks in less-populated counties.
From a planning and policy perspective, the Recycling Facilities Map can serve as a decision-making tool for environmental agencies and local governments. It provides valuable spatial information that can be used to identify areas with limited coverage, plan new collection sites, or evaluate the effectiveness of current recycling programs. Additionally, it supports South Dakota’s broader efforts to meet environmental and sustainability goals by enabling data-driven decisions and encouraging greater public participation in recycling.
Through mobilizing geospatial representation and open-access data, the Recycling Facilities Map demonstrates how GIS can further promote local sustainability and environmental health. It provides users with a tool to locate nearby recycling centers and visualize waste management infrastructure across the state through graphical analysis. This map aligns with DANR’s mission to promote a cleaner and more sustainable South Dakota by making real-time, destination-specific information accessible to communities, researchers, and decision-makers.
In summary, the Recycling Facilities Map is a modern, user-friendly solution for exchanging environmental data on waste resources. Bridging the gap between data availability and public utility, the platform enables consumers to make informed, eco-friendly choices about where and how to recycle. By combining spatial analysis, real-world data, and interactive design, this platform once again demonstrates the potential of GIS technology to promote environmental stewardship, inform policymakers, and inspire community action toward a cleaner, more sustainable planet.

The Regulated Air Quality Facilities Map is an interactive, GIS-based map application available through the South Dakota Department of Agriculture and Natural Resources (DANR) Data and Mapping Portal. It allows users to view all permitted air quality facilities across the state. This web-based application, developed by the South Dakota Department of Environment and Natural Resources (DENR), enables users to review air emission sources statewide, verify permitted operations, and observe environmental impacts at local to regional levels. Its design promotes environmental transparency, regulatory oversight, and public accountability by combining geospatial data with official compliance documentation.
When you open the application, it greets you with a split-screen view. On the right side of the screen is an interactive map that lets users view current and historical facility locations at varying zoom levels. On the left is the legend and layer controls that allow users to choose which data appears on the map and how it is styled. Using color-coded symbols, air quality permits are classified and distinguished by type. Yellow dots indicate Title V-permitted facilities, which emit more than 100 tons of regulated air pollutants per year and fall into specific source categories. Green dots represent Minor Operating Permits, applicable to operations with smaller emissions. Orange dots are area sources, typically smaller operations that may collectively affect local air quality. This clear representation of data makes it easy to see which facilities are emitting and the levels of those emissions.
The base map is powered by high-resolution satellite imagery from Esri, HERE, and Garmin, providing a clear geographic view of every facility. Users can zoom, pan, and move the map to explore different cities, industrial areas, or environmental locations. They can easily find specific facilities by name, ID number, or address using a search bar, enabling quick, accurate access to spatial and regulatory data. At the bottom of the map, an interactive table shows detailed information about each facility: Facility ID, Name, Address, and City. This table is linked to the map: clicking a record highlights its corresponding point on the map; similarly, clicking a point on the map scrolls to that entry in the table.
There is a pop-up window for each facility point with regulatory data. This includes information such as facility ID, name, address, PLSS coordinates (showing their location), and a string of numbers indicating which federal regulations apply. For example, selecting Gillens Station in White River shows that the area falls under 40 CFR Part 63, Subpart CCCCCC, which relates to gasoline dispensing facilities. Additionally, the pop-up buttons allow users to directly download compliance PDFs, such as the Initial Notification of Compliance Status. These records—all maintained by DANR’s Air Quality Program—include essential operational details, such as emission limits, vapor recovery, spill control, and throughput data. This link between spatial data and official compliance reports highlights the transparency and accountability built into DANR’s digital framework.
One of the most valuable features of this map is its layer control panel on the left. Users can switch between different datasets, such as City Limits, Natural Events Action Plan Control Areas, and Air Quality View layers, to enhance contextual understanding. These layers help visualize spatial relationships among industrial development, environmental sensitivity, and proximity to populations. For example, the NR34 Air Quality View layer combines information from the 1996 Natural Events Action Plan and displays locations affected by dust storms or particulates. This layered visualization allows users to compare facility concentrations with urban areas, natural parks, or discussion zones for atmospheric disturbances.
Aside from its presentation, the Regulated Facilities Map is a decision-support system for environmental management. The interface could allow a regulator to zoom in on clusters of high-emission facilities, check compliance with federal and state air quality regulations, and schedule inspections. Researchers and environmental scientists can download spatial datasets to study long-term trends in emissions, pollutant dispersion, and environmental justice issues. The public could explore the map to see how industrial activity impacts nearby communities and local air quality.
By integrating geospatial technology and regulatory data, the Regulated Air Quality Facilities Map shows how modern GIS can support environmental policy. It converts scientific monitoring data into a clear, interactive format, connecting science with understanding. Through this system, DANR not only meets regulatory reporting requirements but also promotes an open-data culture, allowing citizens, planners, and policymakers to act on South Dakota's air resources.
The portal is part of a broader state effort to use digital mapping to enhance environmental transparency and sustainability. By providing a comprehensive view of emission sources, compliance documents, and contextual land data, the Regulated Air Quality Facilities Map is essential for monitoring environmental health in South Dakota. This enables informed decisions regarding mitigation strategies and responsible management of air resources for future generations.

The South Dakota Surface Water Quality Standards dashboard is a tool for overseeing how laws implementing the federal Clean Water Act operate in the state, sharing, and enforcing them. Specifically, it manages the state’s waterways, including lakes, rivers, and streams, to ensure they are safe for public use, promote overall health and cleanliness, and are supportive and protective of their ecosystems. In 1972, almost all states finalized water quality requirements under the Clean Water Act. In South Dakota, these requirements are included in ARSD 74:51, the Administrative Rules of South Dakota. As shown by this document, the dashboard’s content and display specifics are well-defined. The South Dakota interactive map is appropriately framed, with lakes, streams, and impairment status representing primary layers as the user displays the assessed point. The user can easily zoom in by touch to focus on a particular body or pan across the state to see larger maps. Layer Lakes depicts each distinct water body in the state, providing an idea of water body density; Layer Streams reveals the primary rivers in South Dakota as well as their tributaries, providing a thorough view of the state’s hydrograph; and Impairment Status regions Impairment status is the most essential layer and consists of a color-coded, shaded megaregion showing which water bodies are clean and which are not. Impaired water bodies are colored red; these are water bodies that do not fulfill specifications and require more investigation, mitigation, reclamation, or legislation. This distinction enables policymakers, researchers, and the public to identify areas of concern quickly.
In addition to the interactive map, dashboard users may access key information regarding water quality standards. In other words, these standards outline the activities that can be conducted in various types of water bodies, such as swimming, fishing, or protecting sources of irrigation or drinking water for the public. For example, an effort to maintain a river segment for fishing and fish habitat may need only low levels of nutrients, pathogens, or heavy metals to be present. The criteria are both narrative and numeric, designed to protect or enhance water quality. Amount-based benchmarks target specific measurements, such as levels of nitrogen or phosphorus or amounts of dissolved oxygen. Narrative standards describe more general environmental conditions, like inhibiting algal blooms or preserving fish habitats. Collectively, these standards direct enforcement and offer baselines of data to be monitored.
One of the dashboard's most distinctive features is its basemap gallery, which enables users to switch between different styles, including imagery, topography, and human geography. This really opens the usability of the dashboard. For instance, personnel generating technical reports might select a topographic view to visualize terrain features, or researchers might opt for high-resolution images to examine nearby land-use patterns. The dashboard’s versatility makes it attractive to a wide array of users, including government officials, environmental scientists, academic researchers, advocacy organizations, and the public.
The South Dakota Surface Water Quality Standards Dashboard is available to help manage environmental concerns and resources. It integrates fiscal standards with live data and maps for state agencies to meet federal laws. It contributes to transparency by reporting to the citizens. The fact that the state includes data about impaired water bodies demonstrates an effort at accountability. It provides a sense of where problems may need to be addressed and an impetus for action.
The dashboard is an example of how policy, science, and technology can collaborate to optimize resource utilization. It’s a user-friendly tool that provides a comprehensive overview of South Dakota’s surface water quality in accordance with its obligations under the federal Clean Water Act and state administrative rules. With interactive maps, transparent visualizations of impairment status, and direct links to regulatory standards, users can access the information needed to understand, track, and respond to water quality concerns. In the end, this tool is contributing to a larger effort to protect our water resources, ultimately benefiting the overall ecological health and well-being of South Dakotans today and for generations to come.

The DANR Water Quality Monitoring Access Portal is a vital tool provided by SDDANR to support long-term monitoring, assessment, and protection of South Dakota's surface waters. Designed to improve transparency and public access to scientific data, the portal allows users to query a wide network of monitoring sites across lakes, rivers, and streams in South Dakota. The platform integrates chemical sampling, biological assessments, and waterbody support status information to help state and federal agencies, analysts, researchers, students, and the public understand how well their waters meet water quality standards over time.
When users open the app, they see a detailed satellite aerial basemap of South Dakota, overlaid with bright yellow dots representing surface-water monitoring stations. These stations measure various water quality parameters, including physical and chemical data related to environmental conditions and pollution sources. Each point on the map is interactive. Clicking on a station opens a ‘popup’ showing the network station ID (each site has a unique number), the type of sampling—such as chemical testing, fish tissue analysis, or citizen science observations—the waterbody where the station is located, with examples like Big Sioux River and Big Stone Lake. The popup is linked directly to raw monitoring files, reports on support status, and TMDL (Total Maximum Daily Load) assessment reports. These documents help users understand historical changes in conditions, identify known pollutants of concern, and review management strategies that have been implemented.
A legend panel on the right side of the interface provides descriptions of the symbols shown on the map. The yellow points represent chemical monitoring sites, the light green points indicate fish tissue contamination sites, and the orange points show citizen contributions to the monitoring network. In addition to the graphical point data, streams and lakes are represented by color based on their support status for the intended beneficial uses (recreation, irrigation, aquatic life). Waterbodies are displayed in blue with bubbles when water quality is assessed as “supporting,” and in red if they are not supporting due to impairments found during sampling and assessments. With this color-coded system in place, users can easily understand the relative environmental health of various waterbodies.
Layers – The template works well when you enable or disable any of the 12 layers. These layers include highways, interstates, county lines, hydrologic regions, and lake outlines. Additionally, by toggling layers on and off, users can locate monitoring sites within a larger geographic context, see watershed boundary extents, and understand land use relationships that could affect water quality. Getting to sites is easy with the search bar on the left side of your screen. With three search options, users can find data by station ID, waterbody name, or keyword.
Additionally, the system allows interaction with stream and lake polygons. Selecting a stream or lake on the map displays information about that waterbody, including ID number, assessment unit size, and designated-use support status. These pop-ups also include links to other resources for more detailed information, such as the Water Quality Dashboard, support status reports, and monitoring downloads. This networked data setup enables easy transition between general map views, detailed monitoring results, and statewide assessment reports. As a result, users gain a comprehensive understanding of waterbody performance and environmental trends.
By integrating chemical sampling, field observations, geospatial mapping, and public-access tools, the portal enables data-driven decision-making across multiple aspects. Natural resource researchers utilize the portal to investigate pollutant trends, assess environmental risks, and access the impact of restoration efforts. Local governments use the information to guide land-use planning and protect watersheds.

Developed in Markdown, the map serves as the application's framework, allowing users to view well locations across the state or zoom into local neighborhoods, farms, and townships.
On the left side of the screen, in the search panel, you'll find various options to filter well records. The Township-Range-Section search is a key feature that sets this site apart—it helps users locate wells using the Public Land Survey System. By utilizing a township and range grid, this system remains an essential reference for land ownership maps, agricultural development plans, and water rights surveys throughout South Dakota. Landowners, oil drillers, researchers, and other government personnel can search for specific points on the map based on township-and-range or section numbers. Users can also search for wells by county, and when they do, the data is limited to wells within that county.
The Ownership box in the search panel offers more detailed information. Here, you can enter a last name or business name; I found wells being drilled for individuals, farms, corporations, or industrial sites. This tool can be helpful for landowners wanting to find well logs for their property, as well as for consultants conducting groundwater assessments or environmental reviews. Below Ditto, the Well Information box allows users to search for wells based on total depth, well type, driller, and date completed. These options enable further analysis by allowing users to find wells within specific time frames, drilled by companies in the county or region, or for particular purposes (e.g., domestic, municipal, irrigation, test, and industrial wells).
The map updates automatically when you enter search criteria. Like Aurora County, the map might show hundreds of wells clustered together. Each well appears as a yellow point, clearly indicating its location. These visual patterns provide valuable insights into groundwater development, agricultural growth, and water supply distribution for homes or industry in South Dakota. Below the network map, a results table automatically refreshes to show all wells that match the user's specified criteria. The table includes key details such as well owner, type, township/range/section, completion date, and total depth. It also features improved web page performance and the ability to download PDF well logs directly. “This allows the dashboard to be more than just an exploratory tool; it is also a storage location for official documentation needed for permitting, compliance, engineering design, hydrogeologic studies, and property assessment.”
A single well summary opens when clicking any point on the map. A pop-up displays the owner’s name, business name, county, township, range, section (location), well type—e.g., gas or oil; latitude/longitude; driller license number; completion date; permit number; and depth. This high-resolution detail provides both the geographical context and technical construction information users need. The pop-up also includes a “Zoom To” button, which re-centers the map directly on the well—allowing a closer view of nearby land use, roads, fields, or subdivisions. In some cases, satellite imagery replaces aerial imagery, offering more insight into the environment around the well.
Filtering the results table with export options by product. Logged-in users can view references to cases and statutes, which can be navigated within the application. The dashboard is very comprehensive for any professional working with extensive well data, including creating reports, preparing for fieldwork programs, conducting academic research, writing case studies, developing groundwater models, and preparing regulatory submissions.

This extensive dataset enables professionals to evaluate contamination risks, monitor the impact of agriculture, and address public health concerns.
County and Aquifer Tables
The dashboard features tables that analyze groundwater data by county and aquifer, along with well data. These tables provide summary statistics, well counts, location details, and a download link for reports.
Measurement and Print Tools
Clearly, this tool is perfect for hydrologists or planners who need to determine aquifer size (by measuring distance across the watershed) or estimate how far a potential contaminant might travel. Additionally, users can export custom maps and tables as high-resolution PDFs or other formats to create professional reports and presentations using the print feature.
Professional Applications
The Network is valuable to many professionals. Hydrologists and geologists rely on the platform for baseline data to model aquifer recharge, track contamination plumes, and understand how water quality changes over time. Agricultural managers use data to monitor nitrate levels and estimate the impact of fertilizer on groundwater. City planners utilize aquifer data to evaluate potential development sites, worried that new projects could threaten nearby water supplies. Public health officials also employ chemical monitoring (such as ultratrace or water analysis for low-metal content) to determine if drinking water sources are contaminated with arsenic, lead, or pesticides. It also assists in regulatory compliance. Environmental consultants may analyze groundwater data for impact assessments, permit applications, or cleanup plans. The decades-long well data record provides solid evidence for legal, environmental, and planning documents.
Conclusion
The Statewide Groundwater Quality Monitoring Network is more than just a mapping program database; it's a comprehensive decision-making tool. It integrates spatial representation, statistical modeling, and historical data into a single platform. It provides statewide coverage while delivering detailed site-specific information through the connection of 144 monitoring wells across 25 aquifers. Its extensive hydrogeological and hydraulic features are designed for professionals who require an in-depth understanding of groundwater behavior. The dashboard allows users to monitor current conditions and trends, supporting the sustainable management of South Dakota’s most valuable natural resources. For those working in various fields, it means groundwater decisions are based on informed, transparent science.
