Cooney Reservoir, located in south-central Montana, offers diverse paddling opportunities on its 1,000-acre surface. The reservoir, created in 1937 by damming Red Lodge Creek, sits at an elevation of 4,250 feet and is surrounded by Cooney State Park.

Access is convenient via three boat ramps with docks spread around the lake. The main access road is well-signed, running west from Hwy 212 south of Joliet for about 8 miles to reach the dam. From there, roads lead to different park units and launch points.

Summer is the prime paddling season, with water temperatures warming to comfortable swimming levels. The reservoir can get busy, particularly on weekends, with various watercraft sharing the space. Paddlers should be prepared to navigate around motorboats, water skiers, and jet skis.

The reservoir's 1,078-acre expanse offers ample exploration opportunities. The shoreline provides scenic views of the distant Beartooth Mountain Range, enhancing the paddling experience.

Wildlife viewing is a highlight, with over 100 bird species documented in the park. Depending on the season, paddlers may spot American kestrels, sandhill cranes, bald eagles, and even pelicans.

Facilities for paddlers include multiple campgrounds around the lake, with Marshall Cove offering showers and drinking water. Day-use amenities include picnic areas and a fish cleaning station at Red Lodge Arm.

Paddlers should be aware that water levels fluctuate significantly throughout the year, peaking in spring due to mountain runoff. The reservoir serves irrigation purposes, which can affect water levels and potentially paddling conditions.

Non-resident paddlers must pay a $5 day-use fee to access the park. While no specific paddling regulations are mentioned, all boaters should follow standard water safety practices and be aware of potential crowding during peak summer months.
