Come enjoy Fishing at our Lake Cascade. Lake Cascade is fifty-four miles north of Boise, Idaho via State Route 55, this body of water is the result of a dam on the North Fork of the Payette River, and stretches between the Idaho towns of Cascade and Donnelly. The 4,450 acre Lake Cascade State Park can be found just west of Cascade. Fisherman catch Coho salmon, rainbow trout, perch and smallmouth bass, year-round including through the ice in the winter months. Camping, boating, fishing, biking, hiking.
