March 2023 streamflow

Detailed Description

A tile map of the US showing streamgages by flow levels through the month of March 2023. 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. During the month of March, storms brought wetter than normal conditions for much of the U.S. Concurrently, large parts of California, the Southwest and the Mississippi River Basin saw heightened precipitation, while much of the Northwest and Northern Plaines remain dry.
