The Colorado River Delta once spanned nearly 2 million acres and stretched from the northern tip of the Gulf of California in Mexico to Southern California’s Salton Sea. Today it’s one-tenth that size, yet still an important estuary, wildlife habitat and farming region even though Colorado River flows rarely reach the sea.

This 24-page guide provides an overview of the history of the Colorado River Delta, its geographic scope, environmental significance, role within the Colorado River Basin, and issues related to its restoration – including the pulse flow in Minute 319 (the supplemental agreement to the 1944 U.S.-Mexican Water Treaty).
