The park is a desert oasis surrounded by rolling sagebrush hills and out croppings of basalt. The park offers visitors a chance to escape summer heat under shelter of cottonwood, black locust ringed by acres of green grass
- A boat ramp provides access to the lake, which is noted for walleye, sturgeon and other fish. Waterskiing, jetskiing, swimming and boating are popular here. The park has its own pond -- stocked with rainbow trout -- and provides year-round habitat for waterfowl.
Bring the kids, enjoy a day on the water, fish in the pond or play volleyball in the sand court. Hat Rock offers the opportunity to get out and enjoy nature with spacious, well-maintained grounds that offer lots of room for your family or large group to get together for outdoor recreation fun.
Except for the west boat ramp, this park will close for the season October 31 and is scheduled to reopen in spring (the exact date will be determined by the weather; check here for updates). During the winter, there are no restroom facilities open at the park.
