Lake That Predated Salton Sea Came and Went as the Colorado River Changed Course

Before the Colorado River was tamed by dams and dikes it was a free flowing, flooding river that often changed course, sometimes dramatically. Though it typically flowed south to the Gulf of California, in years of powerful floods it would flow into the Salton Sea Basin, and fill it up to form what we call Lake Cahuilla.

Since about 612 B.C. Lake Cahuilla has filled up seven times, the last time in 1733.

Researchers Solve a Colorado River Mystery
