Late fall 2019 water availability data viz (IWAAs concept map)

This animation highlights the USGS Integrated Water Availability Assessments (IWAAs) Program’s evolving capacity to estimate water availability at a national scale by visualizing daily estimates of natural water storage (water present on the landscape such as standing water, snowpack, soil water, and shallow groundwater) for approximately 110,000 regions across the conterminous United States.

The data shown in this visualization were sourced from the National IWAAs concept map, which is currently offline for revisions and enhancements. In late fall 2019, the IWAAs concept map visualized unusually wet conditions in the Northern Plains and Upper Midwest, unusually dry conditions in California that coincided with widespread wildfires, and wet conditions in the Southwest resulting from the remnants of Tropical Storm Raymond.
