10. The basin naturally cycles from full to empty as the Colorado River sweeps across its delta.

When the river flows north it fills the basin. This large lake eventually over-tops the delta and creates a channel to the Gulf of California.

This channel then fills with sediments sending the Colorado River back into the basin.

The filled basin has been named Lake Cahuilla. This lake last dried up sometime after 1580.

The poorly designed canal prematurely shifted the river's course north.
