Photos: Senator Wash and Squaw Lake, February 2021

This page features photos of Senator Wash Reservoir and Squaw Lake along the Lower Colorado River.

Located just above Imperial Dam on the California/Arizona border, both Senator Wash and Squaw Lake are off-river water storage reservoirs designed to regulate the flow of Colorado River water as it passes through the dam and toward the All-American Canal. Both reservoirs have designated recreation areas that include several camping zones and day-use areas that are best known for their boating access and wildlife viewing.

Senator Wash and Squaw Lake are a part of the Imperial Dam Storage Complex, which consists of additional storage reservoirs and diversion canals such as the All-American Canal and the Gila Canal that deliver water to California, Arizona and Mexico.

A federal process is underway to rename Squaw Lake.
