Kootenai and Moyie Rivers Watershed Advisory Group (WAG)

WAGs are groups of interested citizens that 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.

The Kootenai Valley Resource Initiative members served as the WAG for development of this TMDL. The Assessment of Water Quality in Kootenai River and Moyie River Subbasins (TMDL) was developed by DEQ, EPA, and the Kootenai Tribe of Idaho in 2006. The document was submitted to public comment and approved by EPA in January 2007. Subsequent documentation on likely causes of impairment was issued in 2009.
