National Water Information System Web Data for the Nation
This USGS site provides access to water resources data collected at approximately 1.5 million sites in all 50 states, the District of Columbia, and Puerto Rico. The site features real-time and historical data retrievable by geographic area for surface water, groundwater, and water quality conditions such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds. The site also includes an extensive inventory of information about data collection sites at stream reaches, wells, test holes, springs, tunnels, drains, lakes, reservoirs, ponds, excavations, and water-use facilities. About 300 components make up the descriptive elements of the inventory and information may be viewed in summary lists, detailed tables, or a file suitable for input to other programs. Tutorials are provided to help users access the various types of data on the site.
