Alamo River

The Alamo River flows west and north from the Mexicali Valley across the Imperial Valley . The 52-mile-long river drains into the Salton Sea.

The New River, Alamo River, and Salton Sea of the 21st century started in autumn 1904, when the Colorado River, swollen by seasonal rainfall and snow-melt, flowed through a series of three human-engineered openings in the recently constructed levee bank of the Alamo Canal. The resulting flood poured down the canal and breached an Imperial Valley dike. The sudden influx of water and the lack of any drainage from the basin resulted in the formation of the Salton Sea; the rivers had re-created a great inland sea in an area that it had frequently inundated before, the Salton Sink.
