April 2022 Streamflow Conditions

Detailed Description

A cartogram map of the US with proportional area charts for each state showing the proportion of streamgages by flow level. Streamflow levels are shown as percentiles of the historic daily record at each gage, and binned to reflect whether flow conditions are wetter or drier than the historical record. For the month of April, most central and eastern states had high flow conditions for the entire month, while the west stayed comparatively dry.
