Abstract

In 2000, the U.S. Environmental Protection Agency began the process of developing regional nutrient criteria for streams and rivers. In response to concerns about nutrients in streams and rivers by the U.S. Environmental Protection Agency and others, the U.S. Geological Survey National Water-Quality Assessment Program (NAWQA) began studying the effects of nutrient enrichment on agricultural stream ecosystems to aid in the understanding of how nutrients affect the biota in agricultural streams. Streams in three study areas were sampled from 2006 through 2008. These three study areas were in three NAWQA study units: Ozark Plateau (OZRK), Upper Mississippi River Basin (UMIS), and Upper Snake River Basin (USNK). Data collected included nutrients (nitrogen and phosphorous) and other chemical constituents in the water column, biological samples [chlorophyll, algal assemblages, invertebrate assemblages, and fish assemblages (at a limited number of sites)], stream habitat, riparian land cover, and basin characteristics. This report describes and presents the data collected from these study areas.
