Lake Keomah State Park near Oskaloosa in southern Iowa features 366 acres of beautiful woods and picnic areas along an 84-acre lake. Deep woods and marshy areas provide habitat for a variety of wildlife including bullfrogs and blue heron. In the fall, the lake’s trees and shrubs illuminate the environment with their vibrant colors. The park is named after the counties of Keokuk and Mahaska, and many of its facilities such as shelters and day-use lodge were constructed by the Civilian Conservation Corps (CCC) in the 1930s.
