Water Quality Plans & Reports in DEQ's Coeur d'Alene Region

The Coeur d'Alene Region is unique in many ways. First, it shares a border with two states (Montana and Washington), Canada, and three Indian tribes. Since water flows with no regard for humanmade boundaries, staff from multiple agencies and countries frequently collaborate on water quality issues. Second, the region's three large and many smaller lakes are the basis for much of the region's economy. Simultaneously using and protecting these lakes creates both opportunities and challenges. Third, the region overlies Idaho's only "sensitive resource aquifer": the Rathdrum Prairie Aquifer, which provides the sole source of drinking water to nearly 500,000 residents in Idaho and Washington.
