About Lake Mohave
Lake Mohave's water level is 638.87 feet above sea level as of Oct 15, 2026, 8.13 feet below full pool (647 feet), with 1.64 million acre-feet in storage (91% of capacity). That is 1.25 feet higher than a week earlier and 1.35 feet higher than a year earlier.
Davis Dam backs up Lake Mohave along the Colorado River below Hoover, reaching about 67 miles upstream to the base of Hoover's powerplant. Reclamation uses it to re-regulate Hoover's releases so downstream users and the treaty delivery to Mexico receive steady flows. The lake lies within the Lake Mead National Recreation Area.
Total capacity is 1.81M af, over the past five years storage has ranged from 1.44M af to 1.80M af.
Lake Mohave 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.
