Parker Dam holds Lake Havasu between 445 and 450 feet so the Colorado River Aqueduct and the Central Arizona Project can draw water. The lake stays near full while Mead and Powell hit record lows, and federal analysis expects Havasu and Mohave elevations to hold under all alternatives.

About Havasu
Lake Havasu sits behind Parker Dam on the lower Colorado River, along the Arizona–California border. It is the diversion forebay for the Central Arizona Project and the Metropolitan Water District of Southern California.
Parker Dam was completed in 1938 and is operated by the U.S. Bureau of Reclamation. Most water leaving Havasu enters either the CAP canal eastward into Arizona or the Colorado River Aqueduct westward into California, with the remainder continuing down the Colorado.
Daily storage, elevation, and release values come from the USBR Reclamation Information Sharing Environment (RISE). Lake Havasu does not have federally codified shortage tiers, so AZMap presents a percent-of-capacity readout.
