Title: MassGIS 2003 Massachusetts Drainage Sub-basins (Polygons) (March 2003)

Summary: This datalayers contains polygons representing Massachusetts drainage sub-basins (see also the Drainage Sub-basins (Arc) datalayer). 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.

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. The state coastline and boundaries are included in the sub-basin coverages and are differentiated by arc attributes.

Title: MassGIS 2003 Massachusetts Designated Shellfish Growing Areas (Arcs) (October 2000)
Contributors:- Line data
- 2003
- Not owned by MIT (Owned by Harvard)
Summary: The Designated Shellfish Growing Area (DSGA) datalayer was compiled by the Department of Fisheries, Wildlife and Environmental Law Enforcement's (DFWELE) Division of Marine Fisheries (DMF). Three hundred and three growing areas in Massachusetts have been designated by DMF's Shellfish Project. The data are stored in two feature layers: Designated Shellfish Growing Areas (Arcs) and Designated Shellfish Growing Areas (Polygons). A designated shellfish growing area is an area of potential shellfish habitat, and all three hundred and three DSGA's make up the territorial waters (tidal zone out to the territorial line) of the Commonwealth. Growing areas are managed with respect to shellfish harvest for direct human consumption, and comprise at least one or more classification areas. The classification areas are the management units, and range from being approved to prohibited (six different classification types in all) with respect to shellfish harvest. For example, one growing area may be composed of four classification areas, all of which are managed separately (have a classification type the same or different from the rest in the growing area). This coverage reflects classification areas as of July 1, 2000. The dataset was originally issued in October 2000.

Title: MassGIS 2000 Fish Traps (Weirs) (August 1999)
Contributors:- Point data
- 1999
- Not owned by MIT (Owned by Harvard)
Summary: The Fish Traps (weirs) datalayer contains the point locations of fish trap permit holders' traps. These permit holders are licensed by the town in which the traps reside as well as by the MA Division of Marine Fisheries (DMF). Not all locations are active, and attributes in the PAT file reflect which trap was active each year from 1990 through 1998 based on catch reports submitted monthly by the permit holders.

Title: MassGIS 2000 Massachusetts Lobster Harvest Zone Statistics, 1997 (Polygons)
Contributors:- Polygon data
- 1999
- Not owned by MIT (Owned by Harvard)
Summary: This datalayer shows statistics for lobsters harvested (by pounds) from 25 distinct statistical reporting areas covering a large portion of the Gulf of Maine and south, including the territorial waters of the Commonwealth of Massachusetts. Fourteen of the areas compose territorial waters, while the other 11 match those of the National Marine Fisheries Service areas for offshore bodies of water bordering the Commonwealth's territorial areas, including George's Bank. These areas are used mainly on maps for fishermen to report their landings (including lobster harvest), as well as for producing plots in various Massachusetts Division of Marine Fisheries (DMF) annual publications showing landings per area. The data distributed by MassGIS includes statistics for lobster harvest zones only; 1997 is the only year data is currently available.

Title: MassGIS 2003 Massachusetts Major Watersheds (Arcs) (June 2000)
Contributors:- Line data

- Geological Survey (U.S.). Water Resources Division.
- Massachusetts Water Resources Authority.
Summary: This datalayer contains lines representing Massachusetts watershed boundaries (see also the Watersheds (Polygons) datalayer). MassGIS has produced a statewide digital datalayer of the 32 major watersheds covering Massachusetts as defined by the USGS Water Resources Division and the MA Water Resources Commission. The datalayer is called Watersheds. Unlike the Major Drainage Basins layer, the watersheds in this layer extend beyond the state boundary to include the full extent of either the full watershed or a full USGS sub-basin.
