Morelos Dam was built across the Colorado River in 1950, under a 1944 treaty between the United States and Mexico. It stands about a mile below the point where the California border meets the river, between Los Algodones in Baja California and Yuma County, Arizona. The eastern half of the dam lies in United States territory, but Mexico is responsible for all of its maintenance. The dam allows Mexico to divert its allotted share of the Colorado to croplands in the Mexicali Valley, and it is the final dam on the river. It is operated by the International Boundary and Water Commission. On 23 March 2014 a gate was opened to begin an eight-week release intended to restore desert riparian habitat downstream.
