by Jackson Hole. Media

The Wyoming Department of Environmental Quality/Water Quality Division (WDEQ/WQD) is soliciting credible surface water quality data and other information to consider for inclusion in the 2020 Integrated 305(b) and 303(d) Report (Integrated Report). The Integrated Report is prepared on a biennial basis, summarizes the water quality condition of surface waters of the State, and includes the 303(d) List of waters requiring Total Maximum Daily Loads (TMDLs). Credible data include scientifically valid chemical, physical and biological data collected under an accepted sampling and analysis plan, using appropriate quality assurance and quality control. All surface water quality data may, therefore, not be suitable for inclusion in the Integrated Report. It is preferred that all data be submitted in electronic format so they can be readily compiled and analyzed as necessary.

In the most recent version of Wyoming’s Methods for Determining Surface Water Quality Condition (December 21, 2017), the deadline for submission of data was changed from July 15 to April 15 of odd-numbered years. Data and information may be submitted to WDEQ at any time, however, to be considered for inclusion in the 2020 Integrated Report, submissions must be received by 5 PM (MST) on April 15, 2019. Please submit data and information to Ron Steg, WDEQ-WQD, 510 Meadowview Drive, Lander, WY 82520 or Questions can be directed to Ron Steg at 307-335-6980 or
