Placid Lake State Park is a public recreation area located 28 miles (45 km) northeast of Missoula, Montana.

[1] Placid Lake was named after the Adirondack Mountains' Lake Placid by Hiram Blanchard, a New Yorker who moved to the area in 1892 to form the Clearwater Land and Livestock Company.

[5] A dam was completed below the lake's Owl Creek outlet in 1972,[6] and the park was created in 1977.

[3] Park facilities include a swimming area, campsites, and boat launch.

[1][7] The park offers an opportunity to view rednecked grebes, ospreys, common loons, and other species of waterfowl.
