The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

This primer highlights methods used in regional and reach-scale assessments of fluvial erosion hazards (FEH) . Fluvial erosion includes bed erosion, meaning lowering of the bed of a stream, as well as bank erosion, which refers to the retreat of stream banks that occurs as a stream widens or migrates laterally.

The National Water Information System (NWIS) Mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.
