Water Quality Integrated Report

Every two years the Nevada Division of Environmental Protection is required by the Clean Water Act (CWA) to conduct a comprehensive analysis of water quality data associated with Nevada's surface waters to determine whether state surface water quality standards are being met and designated uses are being supported. Nevada’s Water Quality Integrated Report is prepared in accordance with the requirements of Sections 303(d)/305(b)/314 of the Clean Water Act and is intended for use by the public, other entities, and NDEP for water quality management planning purposes.   Due to time needed to gather, verify, and compile data into appropriate databases, the assessment period for the Integrated Report always lags about two years behind the present.

Nevada 2020-2022 Water Quality Integrated Report and associated information:

The 2020 and 2022 assessment periods were again combined into one report, the 2020-2022 Water Quality Integrated Report covering the data collected over a seven-year period, between October 1, 2013 and September 30, 2020.

The FINAL 2020-2022 Water Quality Integrated Report was modified based on feedback from the public, EPA and further review of the report and data.  BWQP included all pertinent information (solicitation of data, public comments with NDEP responses, etc.) into the Nevada 2020-2022 Water Quality Integrated Report document as attachments to keep all the information in one package with the hope of making the Integrated Report process more accessible to the public.
