2/16/2022 - The Connecticut local subwatersheds were used as the starting point for all of the subwatersheds in the project area. In addition to the Connecticut subwatersheds, The National Hydrography Dataset Plus (NHDPlus) Version 2 was used to delineate watersheds. NHDPlus Version 2 is a national, geospatial, surface-water framework that includes elevation, flow accumulation, and flow-direction grids. To delineate areas of the Pawcatuck River Watershed that do not have detailed subwatersheds, batch points were created in GIS at desired breakpoints and the Arc Hydro platform was used . The two subwatersheds sets (Connecticut local and Arc Hydro generated) were integrated into the final draft subwatersheds.
