The 2022 Integrated Report (IR) assesses the quality of the surface waters in the state and identifies waterbodies that are not meeting water quality standards. These standards support the designated beneficial uses that protect water quality for drinking water, recreation, aquatic life, and agriculture. Waterbodies that do not meet one or more of their beneficial uses are classified as impaired in the IR and placed on the Clean Water Act 303(d) list.
The Call for Data for the 2022 Integrated Report was open from March 9, 2020, to April 8, 2021. DWQ thanks those who submitted data for the 2022 IR.
The public comment period for the 303(d) Draft Assessment Methods for the 2022 Integrated Report (IR) was held in January-February, 2021. DWQ has responded to comments and published the final 2022 303(d) Assessment Methods.
