资源简介：
These watershed boundaries were delineated by the Martha's Vineyard Commission (MVC) and the SMAST during the Mass Estuaries studies. Local knowledge and field data along with a computer watershed model were utilized to generate these boundaries. Topological checks were performed to make sure that neighboring boundaries do not overlap. Also, were appropriate, shared boundaries are identical (i.e. where the edge of a sub-watershed overlaps with its major watershed boundary). The Major Watershed boundaries are stored as a separate data layer and can be found within the Dukes County GIS AGOL data collection.
