About Lake Havasu
Lake Havasu's water level is 448.78 feet above sea level as of Oct 15, 2026, 1.22 feet below full pool (450 feet), with 546,279 acre-feet in storage (88% of capacity). That is unchanged from a week earlier and 1.04 feet higher than a year earlier.
Parker Dam impounds Lake Havasu on the lower Colorado, the forebay for two of the Southwest's largest diversions: Metropolitan Water District's Colorado River Aqueduct to coastal Southern California and the Central Arizona Project pumping toward Phoenix and Tucson. Roughly three-quarters of Parker Dam's height sits below the original riverbed, which is why it is often called the deepest dam in the world.
Total capacity is 619,400 af, over the past five years storage has ranged from 498,457 af to 605,080 af.
Lake Havasu is one of the 21 major reservoirs this site totals each day, and one of several it tracks in the Colorado (Lower) basin. For the combined picture, western reservoir levels carries the storage of all 21 on one chart, which is the number to watch when the question is about the West as a whole rather than about this project.
Those figures describe the reservoir at full pool, not today. The chart at the top of this page tracks storage in acre-feet and the elevation table tracks the water surface in feet, so read storage against total capacity for how full the reservoir is, and the elevation against the full pool elevation and maximum depth for the size of the water column behind the dam. The two do not move together one for one: a reservoir narrows as it deepens, so one holding half its capacity still stands more than half as deep.
