NOTICE:  All docks have been pulled due to low reservoir levels.  The Marshall Cove and Red Lodge boat ramps are closed.  The North Shore boat ramp is posted with extreme low water levels and difficult launching may occur.  Please take appropriate precautions.

Pets must be on a leash at all times.

Head to Cooney State Park's reservoir 40 minutes south of Billings to boat, play in the water, camp, and fish. This is the most popular recreation area serving south central Montana, and it's always a busy place in the summer!

The park features good walleye and rainbow trout fishing, abundant boating opportunities, and five campgrounds with 82 campsites and three group use areas available daily around the lake. Nineteen campsites with electricity are available.

The park offers three boat ramps with docks and a fish cleaning station at Red Lodge Arm.

Park size: 309 acres. Elevation: 4,252 feet.
