Water Quality | New England SPARROW

The U.S. Geological Survey (USGS), in cooperation with NEIWPCC and the U.S. Environmental Protection Agency (USEPA), has developed a water quality model called SPARROW (SPAtially Referenced Regressions On Watershed Attributes) to assist in regional total maximum daily load (TMDL) and nutrient criteria activities in New England.

NE SPARROW model data are now available to view and download via the link below:

Funding for this interface, as well as the SPARROW CD, was provided by the Cooperative Institute for Coastal and Estuarine Environmental Technology (CICEET), a partnership of the National Oceanic and Atmospheric Administration and the University of New Hampshire.
