SD DENR Requests Water Quality Data for 2020 Integrated Report

The South Dakota Department of Environment and Natural Resources (DENR) requests water quality data by September 2, 2019 as part of its process to complete a biennial assessment of South Dakota’s lakes and streams.

The 2020 Integrated Report must be completed and submitted to the U.S. Environmental Protection Agency by April 1, 2020. The report provides an assessment of the quality of South Dakota’s surface water resources and identifies the impaired waters that require a total maximum daily load (TMDL). Once TMDLs are determined, local, State, and Federal activities can be directed toward improving the quality of identified waterbodies.

To develop a comprehensive list, DENR is soliciting water quality data to help determine the quality of South Dakota’s waters. Chemical, physical, and biological data will be considered. Beach closure information, including dates, duration and water quality results, is also requested. Data submitted will be shared on DENR’s Water Quality Monitoring Access Portal (WQMAP), which is available for public viewing. Organizations that submit water quality data must operate under an approved Quality Assurance Project Plan or participate in DENR’s quality control requirements and provide documentation upon request.
