The reservoir was constructed by the U.S. Army Corps of Engineers as a multi-purpose (flood control, water supply and recreational) project. It was completed in June of 1981. The reservoir has approximately 98 miles of shoreline. The average depth of the reservoir is 19 feet.


The lower half of the lake has steep, rocky shorelines. Approximately half of the timber in the reservoir basin was left standing. Much of the timber that was clear-cut below existing city lakes was stacked into piles and rows to serve as fish attractors. These fish attractors are anchored in areas where water depths range from 6 to 18 feet. The standing timber and fish attractors are marked with buoys for easy location.

This beautiful Flint Hills park offers 1,100 campsites (including cabins), five shelter houses, two swimming beaches, a modern marina, and a large amphitheater with an indoor-outdoor stage. Squirrels, rabbits, songbirds, and other wildlife can be seen in the park, and the wildlife area boasts good populations of game species such as wild turkey, prairie chicken, quail, geese, and deer. Bald eagles also nest on the area.

The U.S. Army Corps of Engineers has granted responsibility to the Kansas Department of Wildlife and Parks to manage the fisheries and wildlife resources of the area. The wildlife resources are leased by the Corps of Engineers and managed by the Kansas Department of Wildlife and Parks. For your convenience you can RENT-A-CAMP.
