New Online Tool Tracks Water Quality in the Nation's Rivers and Streams

Science Center Objects

A new online graphical data tool that provides annual summaries of nutrient and sediment concentrations and loads and streamflow information is now available from the U.S. Geological Survey (USGS).

Water-quality tracking tool maps

Maps showing the use of the new water-quality tracking tool to track water-quality conditions at 106 river and stream sites throughout the Nation.

The tool can be used to accomplish the following:

  • Compare recent water-quality conditions to long-term conditions (1993–2013) at more than 100 river and stream sites across the Nation
  • Download water-quality datasets (streamflow, concentrations, and loads)
  • Evaluate nutrient loading to coastal areas and large tributaries throughout the Mississippi River Basin

The release of annual nutrient loading information provides water-resource managers with timely information to track how loadings and concentrations are changing with time in response to Federal, State, and local nutrient reduction actions.

Graphical summaries are available for 106 river and stream sites monitored as part of the USGS's National Water-Quality Assessment (NAWQA) Program, the National Stream-Quality Accounting Network (NASQAN), the Cooperative Water Program, and the National Water-Quality Monitoring Council National Monitoring Network (NMN), all of which are now part of the USGS National Water-Quality Network for Rivers and Streams.

This research was funded by the USGS Ecosystems Mission Area’s Environmental Health Program (Contaminant Biology and Toxic Substances Hydrology) and the USGS NAWQA Program provided the funds to develop the online tool.
