Lake Bennett is a state-park lake in the Ozark foothills northeast of Greenbrier, Arkansas. The forty-acre lake is named for Hugh H. Bennett, the first director of the U.S. Soil Conservation Service (USCS). The Civilian Conservation Corps and the Works Progress Administration constructed the lake as part of the first USCS erosion control demonstration project in the United States. The lake is stocked with largemouth bass, catfish, crappie, and bluegill.
The lake sits inside the boundary of Woolly Hollow State Park. There is a beach on the north shore of the lake, as well as a dock with paddle-boats for rent, a children's playground, several shelters, and many picnic tables.
