U.S. River Conditions, October to December 2024 thumbnail image. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.

The three Integrated Water Availability Assessment products are designed to be interdependent: 

Water limitation across the lower 48 United States, shown as the average from 2010 to 2020 for each watershed (HUC12). Water limitation levels were based on the surface water supply and use index, which expresses the imbalance between surface water-supply and consumptive use.

This is a thumbnail for an animation showing the changing conditions relative to the historic record of USGS streamgages from October 1, 2023 - September 30, 2024. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles).
