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.

Water Data for the Nation (WDFN) is the home for USGS’s modernization of public delivery of water data.

This site is the home for modernized access to USGS water data in machine-readable formats via REST APIs, a common type of web service programs use to search and download data. These services provide USGS water data, ranging from continuous measurements of streamflow to information about individual USGS sites and more.

Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. The Water Data Blog posts highlight water data developments, data, and applications.

These data and application are provided as part of USGS research on contaminants in surface waters across the United States and supported by the USGS Water Mission Area Proxies Project and the USGS Ecosystem Mission Area Environmental Health Program (Toxic Substances Hydrology).

The Fairfax Water Quality Dashboard provides access to water quality data from 6 intensive monitoring stations and 15 trend monitoring stations in Fairfax County.

The Hampton Roads Water Quality Dashboard displays data from 12 water-quality monitoring stations across the cities of Chesapeake, Hampton, Newport News, Norfolk, Portsmouth, and Virginia Beach. This application provides access to current conditions at each monitoring station and visualize timeseries plots for continuously monitored parameters collected at each monitoring stations.

This application is intended to help emergency, environmental, and public health managers at the federal, state, and local levels in West Virginia evaluate, plan for, and respond to potential drought conditions in at-risk communities. It uses estimated public water supply withdrawal rates to symbolize modeled drought conditions once every hour using National Water Model streamflow estimates.

This interactive narrative summarizes a new U.S. Geological Survey report wherein monitoring data collected between 2007 and 2018 are used to provide insights into the changing water quality of urban streams in Fairfax County and the potential role of water-quality management practices.

The Potomac Wastewater Mapper is intended to help identify streams with elevated wastewater conditions or predicted ecological risk posed by municipal effluent-derived wastewater mixtures that may require further attention by resource managers, either through targeted contaminant monitoring and sampling or wastewater treatment plant upgrades to improve contaminant removal.

Groundwater levels in layered aquifer systems like the Virginia Eastern Shore are often monitored using wells in multiple aquifers at the same location. Colors in the simplified cross-section illustration below correspond to the circles representing wells on the map. The list of monitoring-well layers can be used to control the map display of wells for individual aquifers.
