Tracking Water Quality of the Nation’s Rivers and Streams
A new online graphical data tool that provides annual summaries of nutrient and sediment concentrations and loads and streamflow information is now available.
The tool can be used to:
– compare recent water-quality conditions to long-term conditions (1993-2013) at each site,
– download water-quality datasets (streamflow, concentrations, and loads), and
– evaluate nutrient loading to coastal areas and large tributaries throughout the Mississippi River Basin.
The release of annual loading information provides water resource managers with timely information to track how loadings and concentrations are changing over time in response to nutrient reduction actions.
Graphical summaries are available for 106 river and stream sites monitored as part of the U.S. Geological Survey’s National Water-Quality Network for Streams and Rivers, which includes sites in the National Water-Quality Assessment Program (NAWQA), National Stream-Quality Accounting Network (NASQAN), the Cooperative Water Program, and the National Water-Quality Monitoring Council National Monitoring Network (NMN).
Pesticide data will be included in future updates.
