December 2023 Streamflow Tile Map

A tile map of the US showing streamgages by flow levels through the month of December 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 December, much of the Northeastern U.S. and Pacific Northwest saw wet conditions for stats such as Connecticut, Rhode Island, Vermont, New Hampshire, Massachusetts, New Jersey, New York, Oregon, and Washington, while states such as Louisiana, Mississippi, and Alabama in the Southern U.S. saw relatively dry conditions.
