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.
See a current list of Restrictions and Closures on State Parks and other FWP lands that may be affected by floods, fire, drought or major maintenance activities.

AIS can be easily spread from one waterbody to the other. Anglers, boaters, construction workers, pond owners, gardeners, seaplane pilots, field workers - virtually anyone who works or plays in or around water can unknowingly transport these pests on their boats and equipment. It takes only one mistake to potentially infest a new water body.
