List of valleys of the Lower Colorado River Valley

This is a list of valleys within the Lower Colorado River Valley corridor, from the Hoover Dam (Lake Mead) region, south to the Mexico border.

Six valleys are contained within neighboring bajadas and mountain ranges, on the Colorado River proper; other tributary valleys flow during desert rain episodes, and are otherwise dry washes. Only higher elevation associated mountains may have longer sustained pools of water in dry wash riverbeds.
