Painted Rock Dam

Painted Rock Dam is an embankment dam across the Gila River that creates a large reservoir for water management. The structure helps control seasonal flooding and supports irrigation for farming areas downstream.

The dam was built between 1957 and 1960 by the United States Army Corps of Engineers. The project was part of water management development efforts in the lower Gila River region.

Ancient petroglyphs near the dam site demonstrate the presence of indigenous settlements before Western expansion into the territory.

The dam and reservoir area are accessible from public roads and offer fishing and recreation opportunities. Visit during cooler months when temperatures are more comfortable for outdoor activities.

Construction of the dam resulted in flooding of lands belonging to the Tohono O'odham Gila Bend Reservation. This significantly affected the tribe's traditional farming areas and water access.
