Iowa lake levels: common questions
Are Iowa lakes low right now?
0 of the 10 Iowa 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 Iowa lake has changed most this week?
Coralville Lake has risen the most, +1.00 ft over seven days, and Lake Red Rock has fallen the most at -3.34 ft.
How often do Iowa 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. Army Corps of Engineers 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.
