Drainage divides, Massachusetts; Deerfield and Millers River basins

Drainage boundaries for selected subbasins in Franklin and northwestern Worcester Counties, Massachusetts, are delineated on 16 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and for mouths of major rivers. Drainage basins are shown for the outlets of lakes or ponds and for streams where the drainage area is greater than 3 square miles. Successive sites along watercourses are indicated where the intervening area is at least 6 square miles on tributary streams or 10 square miles along the Millers and Deerfield Rivers, or 20 square miles along the Connecticut River.
