The National Water Data Exchange (NAWDEX) was established by the United States Geological Survey in 1976. NAWDEX serves as a national focal point for cataloging and indexing water data that are available throughout the nation, and it provides the necessary linkages between the collector and user communities. Available water data have been indexed for over 400 organizations. Additionally, information has been gathered on over 700 organizations that are collectors of water data or involved in water-related programs. Aid in indentifying and locating needed water data is provided by a network of assistance centers located in 45 states and Puerto Rico.
