Spillway Campground

The Spillway Campground is a small campground with 3 campsites along Anderson Ranch Reservoir. The reservoir is a popular destination for fishing, boating, waterskiing and riding personal watercraft. There is excellent fishing in the reservoir for smallmouth bass and kokanee. Also try your luck at fly fishing just below the dam for a trout! Rafting access is at Reclamation Village, just south of the campground.
