U.S. Geological Survey - Environmental Health
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).
The tool can be used to accomplish the following:
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.
The USGS NAWQA Program provided the funds to develop the online tool.
