Washington lake levels: common questions

Are Washington lakes low right now?

8 of the 18 Washington lakes with enough history to compare are in the bottom quarter of their own September 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 September may still be entirely normal for the date.

Which Washington lake has changed most this week?

Lake Shannon has risen the most, +5.25 ft over seven days, and Keechelus Lake has fallen the most at -34.59 ft.

How often do Washington 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.
