Operational guidelines for assistance centers of the National Water Data Exchange

The National Water Data Exchange (NAWDES) is a nationwide program managed by the U.S. Geological Survey to assist users of water data and water-related data in identifying, locating, and acquiring needed data. NAWDEX services are available through a program office located in the Geological Survey 's National Center in Reston, Va., and a network of assistance centers established in 45 States and in Puerto Rico to provide local and convenient access to NAWDEX facilities. This manual presents operational guidelines for the operation of these assistance centers to accomplish the expeditious flow of data from holder to user. These guidelines will be occasionally modified and supplemented to accommodate new concepts and techniques that may be needed. (USGS)
