National Water Information Network

The U.S. Geological Survey has established a new service, the National Water Data Exchange (Nawdex), which will provide local assistance to governmental agencies and the public in identifying, locating, and acquiring available water data.

Centrally managed by a program office at the USGS National Center in Reston, Virginia, Nawdex now provides local services through a national network of 51 local assistance centers located in 45 states and Puerto Rico. These centers, linked by computer terminals, provide rapid access to information about the availability of more than 1 billion measurements of streamflow, groundwater levels, sediment discharges, and the quality of surface water and groundwater for thousands of stations operated by more than 300 organizations across the country.
