A tile map of the US showing streamgages by flow levels through the month of September. 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 slow levels to the historic daily record for each streamgage.

A cartogram map of the US with proportional area charts for each state showing the proportion of streamgages by flow levels, categorized using percentile bins. Streamflow level percentiles are calculated using the historic daily record for each gage, and binned to reflect whether flow conditions are wetter or drier than the historical record.
