National Water Census
National estimates of water budget components for local watersheds, water withdrawal data for counties, tools to calculate statistics of daily streamflow records, modeled daily streamflow at ungaged stations, and access to records of aquatic biology observations.
This data visualization shows how three major components of the water budget, precipitation, evapotranspiration, and runoff, vary across the conterminous US.
