The lake is off State Route 87, about halfway between Phoenix, Arizona and the ghost town, Sunflower. The dammed end of the lake is at 33°33 56 N 111°32 10 W / 33.5656°N 111.5361°W / 33.5656; -111.5361, at an elevation of 1,506 feet (459 m). This lake is also part of the Tonto National Forest, as such the facilities located here are managed by that authority. The Desert Bell is a tour boat that goes out often in spring, less in summer. The lake is stocked with fish.
