Cooney State Park

Cooney State Park is a 309-acre area built around a water reservoir situated at 4,252 feet elevation in Carbon County. The site has three boat ramps and five distinct camping zones designed for different types of visitors.

Cooney Dam was built in 1937 to create a water supply for regional irrigation needs. The surrounding area was established as a state park in 1970 to open it for public recreation.

The reservoir serves as a gathering place where local anglers and water sports enthusiasts spend their leisure time, keeping alive traditions of outdoor recreation in this part of Montana. The boat ramps and camping areas show how the community has shaped the place for relaxation and connection.

The park offers 82 campsites with varying levels of equipment and amenities, with some featuring electrical hookups for RVs. Visitors should check which areas match their needs and ask about road and facility conditions before planning a visit.

The water is known for its healthy fish populations, especially walleye and trout, which draw anglers from across the region. During colder months, the frozen surface becomes a destination for ice fishing enthusiasts who venture onto the ice with their rods.
