Saguaro Lake was created on the Salt River by the completion of the
Stewart Mountain Dam in 1930. The dam, managed by the Salt River Project, is 212 feet high and 583 feet long, and has a 13,000-kilowatt hydroelectric generator. It was the last dam to be built on the Salt River. Named for the majestic Saguaro Cactus and situated about 40 miles northeast of Phoenix in the Tonto National Forest, Saguaro Lake is the fourth and final reservoir on the Salt River. It is approximately ten miles long, has over twenty-two miles of shoreline, and can hold nearly seventy thousand acre-feet of water.
