River Level Dashboard

River stage (gage height) at major U.S. gauges since 2000. Because each gauge has its own local datum, every river is plotted as the change in feet from its first reading, so flood peaks and drought lows line up for comparison. The Mississippi at St. Louis swings most — from record 2022 drought lows to towering flood crests.
