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.
