Shoreline Management Areas in Kootenai County include areas adjacent to rivers, lakes and streams. The county regulates activities in these areas before, during and after construction to help water quality and aquatic habitat from property erosion and nutrient loading. The county's goal is to promote the continued health of our lakes and rivers while respecting the rights of property owners. Read below for an overview of Shoreline Management Areas.
Kootenai County's Shoreline Management Area is 25 feet landward in slope distance from the ordinary high water mark of all recognized lakes, the Coeur d'Alene River and the Spokane River.
