The National Water Quality Network (NWQN) for Rivers and Streams includes 110 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program, National Water-Quality Assessment (NAWQA) Project. The NWQN includes 20 large river coastal sites, 41 large river inland sites, 30 wadeable stream reference sites, 10 wadeable stream urban sites, and 9 wadeable stream agricultural sites. In addition to the 110 NWQN sites, 3 large inland river monitoring sites from the USGS Cooperative Water Program are also included in this annual water-quality reporting Web site to be consistent with previous USGS studies of nutrient transport in the Mississippi-Atchafalaya River Basin....

The National Water Quality Network (NWQN) for Rivers and Streams includes 110 surface-water river and stream sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program. This data release provides streamflow, nutrient, and sediment data collected and analyzed by NWQN for sites used to represent contributions to the Gulf of Mexico from 1968-2021. This dataset includes daily, monthly, and annual summaries of streamflow conditions, discrete water-quality concentrations, annual water-quality loads, and information on water-quality trends. Data from this release will be presented on the USGS ScienceBase platform.

This dataset is the basis for the U.S. Geological Survey Scientific Investigations Report "An evaluation of methods for computing annual water quality loads", which utilized available data from Heidelberg University and the U.S. Geological Survey to evaluate the accuracy of various methods for computing annual water-quality loads. This dataset contains two files used in the report: "QW_FLOW.csv", which contains the water-quality sample and streamflow data used to develop water-quality load estimates, and "QW_LOAD.csv", which contains observed and estimated annual loads.
