Status: In Progress


Location

The Black Rock Slough Wetlands Project is located within the Idaho Department of Fish and Game (IDFG) Coeur d’Alene River Wildlife Management Area. Black Rock Slough is near Killarney Lake and south of the Coeur d’Alene River.

Background

Black Rock Slough is hydrologically connected to and significantly affected by Coeur d’Alene River water levels and the downstream management of the Post Falls Dam on the Spokane River. The river’s floodwaters deposit sediments contaminated by historic mine wastes that limit recreational use and degrade wetland productivity important to water fowl.

Plans

IDFG will install three water control structures in Black Rock Slough to manage water flow. The structures will hold sediment-laden river water out of the slough and reduce recontamination risk. Black Rock Slough will have a more natural hydrology and natural summer draw down of water levels. The structures will allow retention of shallow water during the fall waterfowl migration.

Benefits

The project will restore wetlands to a healthy natural state, prevent recontamination from other sources, and benefit diverse waterfowl species and other wildlife using the Black Rock Slough wetlands habitat.
