Formed by the Ozark Jeta Taylor Lock & Dam in 1969 on a sweeping bend in the Arkansas River, both the lake and neighboring town got their name from the French â âAux Arcâ (pronounced Ozark) meaning the Big Bend. The surrounding public land is designated a State Wildlife Management Area. Containing about 10,600 acres of water Ozark Lake provides exceptional recreational adventure and outdoor fun within its 173-mile shoreline. Multi-species fishing is good year-round. Recreational facilities found nearby include picnic and camping amenities, RV Park, boat ramps, hiking trails, playground equipment, and overlook pavilion.
