Wyoming lake levels: common questions
Are Wyoming lakes low right now?
7 of the 18 Wyoming lakes with enough history to compare are in the bottom quarter of their 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 Wyoming lake has changed most this week?
Meeks Cabin Reservoir has risen the most, +7.13 ft over seven days, and Buffalo Bill Reservoir has fallen the most at -2.30 ft.
How often do Wyoming 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 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.
