Description: The Oregon Department of Environmental Quality uses water quality standards to assess whether the quality of Oregon's rivers and lakes is adequate for fish and other aquatic life, recreation, drinking, agriculture, industry and other uses. DEQ also uses the standards as regulatory tools to prevent pollution of the state's waters. The Clean Water Act requires states to adopt water quality standards designating beneficial uses of the state's waters and setting criteria designed to protect those uses. States submit their standards to the federal Environmental Protection Agency for approval. This feature contains a spatial representation of Oregon's Water Quality Standards.The fish and spawning use designations included in this layer are intended to be as accurate as possible, however some errors may exist. In addition, the Oregon Environmental Quality Commission has approved and DEQ has submitted to the Environmental Protection Agency updates to the fish and aquatic life use designations. As of April 2025, EPA has not taken action on these updates. If approved, these updates will change the fish use designation and applicable temperature criteria for some AUs. In the case of any discrepancy, the applicable temperature criteria and geographic extent described in rule at OAR-340-041 shall take precedence over the layers in the GIS data.
