Saguaro Lake is the fourth reservoir on the Salt River, formed by the Stewart Mountain Dam in the U.S. state of Arizona. The lake is off State Route 87, about halfway between Phoenix and the ghost town of Sunflower. The dammed end of the lake is at 33°33′56″N 111°32′10″W / 33.5656°N 111.5361°W, at an elevation of 1,506 feet (459 m).
This lake is within the Tonto National Forest; the facilities are managed by that authority.
A large fish kill was documented in the lake in 2017-2019 and in 2022, due to golden algae.
