Targeted watershed boundary for the Connecticut National Estuarine Research Reserve (CT NERR). This watershed boundary file is intended to provide a spatial unit to represent the watersheds that most directly affect the ecosystems and communities within the CT NERR, and facilitates various watershed characterizations and analyses.

The watersheds represented by this file were extracted from the 12-digit Hydrologic Units contained in the Watershed Boundary Dataset (WBD). The first step was to identify the 10-digit HUCs that most closely represented a consistent and continuous extent for watersheds flowing across and into to the existing upland and coastal/offshore reserve boundary. All 12-digit HUCs that were contained in the selected 10-digit HUCs were then selected and additional 12-digit subwatersheds were added to the selection to ensure that all subwatersheds contributing to the reserve boundary were included.
