Protecting Public Health and the Environment.

Spokane River Watershed Advisory Group (WAG)

WAGs provide local public input and guidance to DEQ during the development of water quality improvement plans or TMDLs for water bodies that fail to meet water quality standards. TMDLs are designed to reduce the levels of pollutants, such as bacteria and sediment, in impaired water bodies.

Content on this page is provided for informational purposes while the Spokane River WAG and DEQ work to develop a TMDL to address cadmium, lead, and zinc contamination within the watershed. Through this cooperative effort and continued public involvement, DEQ's goal is to develop a comprehensive plan aimed at restoring all beneficial uses within the watershed.

Next Scheduled Meeting Date

To be determined


The Idaho portion of the Spokane River flows westerly approximately 10 miles from the outlet of Coeur d’Alene Lake to the Idaho/Washington border in northern Idaho. The Idaho portion of the Spokane River is wholly located in Kootenai County and flows through the communities of Coeur d'Alene, Huetter, and Post Falls.

DEQ has identified that past Spokane River water concentrations of cadmium, lead, and zinc exceed Idaho water quality standards criteria.
