Cascade is the county seat for Valley County, a scenic rural county located in west central Idaho. Established in 1917, it was named after the Long Valley of the North Fork of the Payette River, which extends over 30 miles from Payette Lake at McCall south to Cascade and on to Round Valley. The population of Valley County was 9,862 at the 2010 census.

The economy of the Lake Cascade Recreation Area has been recognized as a superb location for recreation, sports and simply “getting away from it all.” Employment opportunities in the area are therefore varied and run the gamut from ranching, logging and National Forest positions to many choices in health care, recreation and visitor services, retail and other small business opportunities.
