Stewart Mountain Dam

Stewart Mountain Dam is a concrete arch dam that spans across the Salt River, creating Saguaro Lake to the northeast of Phoenix. The structure harnesses water flow to generate electricity for the surrounding region.

The project was built between 1928 and 1930 as part of the Salt River Valley Users' Association power system. It represented a significant step in developing water resources for the growing Phoenix region.

The National Register of Historic Places added the dam in 2017, recognizing its engineering excellence and contribution to regional development.

The visitor area near the lake offers information about the power generation facility and regional history. The best time to visit is in early morning or late afternoon when temperatures are more comfortable.

Construction workers lived in a temporary camp that was later transformed into a guest ranch after the dam was completed. This repurposing shows how project infrastructure shifted to serve recreational use.
