Description
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 an elevation of 1,506 feet (459 m). A large fish kill was documented in the lake in 2017-2019, and 2022,due to golden algae from the poor management of the Salt river chain by the AZGFD.
