About this park

Created in 1967, the 26,000-acre lake is recognized as one of the nation's top ten inland sailing lakes and hosts several races and regattas. The lake is home to an array of wildlife that can be seen throughout the year. Its waters and shores are a resting spot for migratory waterfowl and other birds, and there are six established Watchable Wildlife Sites with viewing towers open to the public around the lake.
