Mormon Flat Dam

Mormon Flat Dam is an arch dam in Arizona measuring 116 meters long, built across the Salt River to generate electricity. The facility operates with two generator systems working together to meet the region's varying power needs throughout the day.

The Salt River Project built this dam between 1923 and 1925 to meet growing water and power demands for agriculture in the Salt River Valley. The project was part of a larger effort to develop Arizona's infrastructure during the early 1900s.

The Federal Energy Regulatory Commission maintains documents about Mormon Flat Dam through photographs, drawings, and maps for educational purposes.

Visitors can explore the dam area, though access to certain sections may be restricted for safety and operational reasons. Bring sun protection and water when visiting, as the surrounding landscape offers little shade during hot months.

The dam is notable for creating Canyon Lake, a reservoir that enables recreation and water sports in an otherwise arid landscape. This lake has become a popular destination for locals and visitors who enjoy fishing, boating, or simply walking along the shoreline.
