Hydrologic Units for the Boston Harbor Digital Coastal Habitat Atlas
This dataset shows the management units for the Boston Harbor Digital Coastal Habitat Atlas. The Boston Harbor watershed was divided into management units to help users to identify relevant data in their municipality or sub-watershed. The planning units were delineated on both the land side and in the nearshore environment using the MassGIS Sub-basins data layer. All sub-basins with tidal frontage within the Boston Harbor Digital Habitat Atlas study area were selected. Water-side hydrologic units were created to denote large management units with similar hydrologic input.
