The National Stream Survey (NSS), conducted in the spring of 1985 and 1986, is one component of the U.S. Environmental Protection Agency's National Surface Water Survey. This effort is in support of the National Acid Precipitation Assessment Program. The NSS was a synoptic, spring survey of 500 streams in regions of the Southeastern and Mid-Atlantic United States expected to contain larger numbers of low alkalinity streams. The NSS is based on a probability sample from an explicitly defined population of surface waters. In the NSS, 500 streams were sampled, representing a regional population of 64,700 stream reaches. The NSS database includes stream and watershed physical characteristics, in situ measurements, and water chemistry data. Accompanying the database is a comprehensive user's guide that provides an overview of the NSS design, database structure, and transfer media.
