DENR Requests Water Quality Data for 2020 Integrated Report


PIERRE, S.D. – The South Dakota Department of Environment and Natural Resources (DENR) requests water quality data 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). A TMDL calculates the amount of pollution a waterbody can receive and still meet water quality standards along with supporting assigned beneficial uses. Once TMDLs are determined, local, state, and federal activities can be directed toward improving the quality of the waterbody.


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, to include date, duration and water quality results, is also requested. Data submitted will be shared on DENR’s WQMAP: Water Quality Monitoring Access Portal and 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.


DENR’s 2018 Integrated Report is available online at http://denr.sd.gov/documents/18irfinal.pdf.


Persons or organizations having electronic water quality data should contact Paul Lorenzen at 1-800-438-3367 or email Shannon.Minerich@state.sd.us or Paul.Lorenzen@state.sd.us by September 2, 2019.
