March 2025 Streamflow

Streamflow tiles show flow levels through the month of March 2025. Wet conditions dominated much of the West Coast and Northeast, while near normal conditions persisted for much of the Central U.S. For each state, an area chart shows the proportion of streamgages in wet, normal, or dry conditions. Streamflow conditions are quantified using percentiles comparing the past month’s flow levels to the historic record for each streamgage.
