Looking to fish?

Cooney has been a state park since October of 1970, and new visitor amenities have been added slowly over time. The 97 ft tall earthen dam on Red Lodge Creek that forms the reservoir was constructed in 1937 as part of a larger irrigation project for nearby farmers and ranchers.

Not only does the park have a gorgeous reservoir, but it has great views of the Beartooth Mountain Range in the background.

Regardless of the season, you’ll find excellent fishing for walleye and rainbow trout. And don’t forget, the Red Lodge Arm has a fish cleaning station!

Planning to bring your boat along? You shouldn’t have any issues finding a place to drop in with three boat docks and ramps surrounding the lake!

During the winter, some people enjoy kite-skiing across the lake! 

Camping is plentiful at Cooney State Park, with five campgrounds and 82 campsites, 19 of which have electricity! While the electricity in the campgrounds is on year-round, be aware the water is shut off during the winter months. 

There are also three day-use group areas available around the lake.

Curious what other visitors have had to say about the park?

"Moon coming out on a beautiful night on Cooney, fireworks northeast, south Red Lodge mountain still snow on the runs, people laughing in the distance having fun, winds died so this sailboat not going anywhere, on the hook south of Red lodge camping area wow it really doesn't get any better than this!"

"Park Ranger and the camp host were both really great with answering all our questions and giving directions to camp and nearest local convenience store! The campground is clean and beautiful, right on the lake, but not much shade so come prepared!"

"Every day of fishing is a good day. Mostly with scenery like this."

"It's an awesome place! Boat ramps, fishing, boating swimming, fires and camping! And you can rent kayaks and paddle boards."


"Just a little piece of heaven."
