Some of the lakes the U.S. Army Corp of Engineers manages include Lake Sonoma in Geyserville, California, Lewisville Lake in Lewisville, Texas, and Monroe Lake in Bloomington, Indiana. Lake Sonoma is in California's wine country. All facilities are managed by the Corp of Engineers, including two campgrounds, one with parking space for boats and a boat ramp. Multipurpose trails rim the lake and picnic areas are strategically placed. Playgrounds are available at Warm Springs, Yorty Creek and Liberty Glen.
Lewisville Lake, located just north of Dallas, covers 29,592 acres and is surrounded by more than 20 parks. The Corp of Engineers manages boat ramps, including the Big Sandy Ramp Westlake and Doe Branch Access, as well as campgrounds at Hickory Creek. Private parties run the Pier 121 Marina, the Tribute Golf Course and various RV and tent campgrounds.
Monroe Lake sits in southern Indiana, in what is deemed the "Limestone Capital of the World." Once part of the inland sea that covered the midsection of the continent, the area was once mined for salt. The creek used to get the salt to market was Salt Creek, which today is Monroe Lake. The U.S. Army Corp of Engineers manages the trails, playgrounds and admission to the dam overlook and the Tailwater section. The marina and lodgings are managed by private parties.
