Protecting Public Health and the Environment.

Black Lake 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.

The Black Lake WAG was formed in 2009 to develop and implement a nutrient TMDL to improve water quality in Black Lake. The Black Lake Watershed Assessment and Total Maximum Daily Load was developed in conjunction with EPA and the Coeur d'Alene Tribe, with the goal of producing one TMDL protective of both reservation and state waters. The document was approved by EPA in 2011. The document may be viewed on the Black Lake Subbasin webpage.
