Arizona lake levels: common questions
Are Arizona lakes low right now?
1 of the 3 Arizona lakes with enough history to compare is in the bottom quarter of its own October record. That seasonal comparison matters more than the raw level: reservoirs are drawn down on a schedule, so a lake several feet below full pool in October may still be entirely normal for the date.
Which Arizona lake has changed most this week?
Horseshoe Reservoir has risen the most, +4.79 ft over seven days, and Lake Powell has fallen the most at -0.01 ft.
How often do Arizona lake levels update?
Each gauge publishes on its own schedule. Most report at least daily, some hourly. This page is rebuilt every day from the U.S. Bureau of Reclamation and the U.S. Geological Survey, and the number on an individual lake's page refreshes again in your browser when the agency posts a newer reading. Readings are provisional and can be revised.
