New England SPARROW (SPAtially Referenced Regressions on Watershed Attributes) are statistical models that provide a regional interpretation of water-quality monitoring data for streams. The models are documented in the report Estimation of Total Nitrogen and Phosphorus in New England Streams Using Statistically Referenced Regression Models, and a brief overview is available on the "About New England SPARROW" page.

The U.S. Geological Survey, in cooperation with the New England Interstate Water Pollution Control Commission (NEIWPCC), has developed this interactive web-based interface for viewing and accessing New England SPARROW data. The model input, as well as results, can be viewed and accessed for over 42,000 stream reaches throughout New England. Base data layers that can be used for geographic reference include streets, waterbodies, streams, digital topographic maps, and digital orthophotographs.
