Sub-basin Boundaries (Polygons)

Entry ID: MassGIS_GISDATA.SUBBASINS_POLY

[ Update this Record ]

Summary

Abstract: MassGIS has produced a statewide digital datalayer of the approximately 2300 sub-basins as defined and used by the USGS Water Resources Division and the Mass Water Resources Commission and as modified by Executive Office of Environmental Affairs (EOEA) agencies. These sub-basins were aggregated together to make the 28 basins of the Major Basins Datalayer. Cape Cod and the Islands do not have much lateral 'surface' drainage because the soils are so porous. The sub-basin line shown for Cape Cod is the approximate groundwater divide between Cape Cod Bay, Vineyard Sound, and the Atlantic Ocean, taken from sub-surface groundwater contours. In ArcSDE are two layers: SUBBASINS_ARC and SUBBASINS_POLY.
