Summary

In 2013, the Regional Stream Quality Assessment (RSQA) study was started as part of the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) project. One of the objectives of the RSQA is to characterize the relationships between water-quality stressors and stream ecology and subsequently determine the relative effects of these stressors on aquatic biota within the streams (Garrett and others, 2017; Journey and others, 2015; Coles and others, 2019; Sheibley and others, 2017; May and others, 2020). The study was implemented in five regions across the United States (U.S.); the Midwest (MSQA) in 2013, the Southeast (SESQA) in 2014, the Pacific Northwest (PNSQA) in 2015, the Northeast (NESQA) in 2016, and California (CSQA) [...]

Purpose

As one of the four fundamental Geographic Information System (GIS) datasets used to summarize and compile GIS characteristics for the RSQA, this dataset was created to record the location of the RSQA water-quality sampling locations. These sites were then used to delineate the watersheds used to summarize and compile environmental characteristics for the RSQA (Qi and Nakagaki, 2020). The site characteristics assist with the analysis and interpretation of water-quality and biota data collected for the RSQA study and were also used as input into various ecological models.
