Subwatershed Studies

There are a total of ten subwatersheds within the Pennichuck Watershed as identified in the 1998 Pennichuck Water Works Watershed Management Plan. One primary recommendation from the Watershed Management Plan was to perform a detailed review of each of the subwatersheds to identify best management practices that could be applied to minimize pollutant loadings from existing impervious surfaces, and to prevent pollutant impacts from future development. The studies completed to date are archived below.
