Things To Do


Allow the beauty of Lake Keomah State Park to soothe your mind. Find a shady picnic area with a lovely lake view to enjoy a picnic lunch. Take a leisurely afternoon to wander the trails along the shore, swim in the lake or cast a line from boat, pier or jetty.

During the summer the open water, grasslands, deep woods and marshy areas provide habitat for all types of wildlife. Hikers along the park's scenic hiking and nature trails may catch a glimpse of bullfrogs blowing and puffing bass solos, a great blue heron wading the shallows in search of minnows, or a covey of quail rising at the approach of human footsteps. In the fall, the lake is surrounded by a mass of color from a variety of trees and shrubs.

"Keomah" may sound like an Indian name, but it is not. The name is derived from the first syllables of the two counties that helped finance the park over 50 years ago --Keokuk and Mahaska. A portion of the south side of the lake was reserved for private development and many homes dot this side of the lake. The park was dedicated in 1934. Many of its facilities were constructed by the Civilian Conservation Corps (CCC).
