Fishing Grounds of the Gulf of Maine
Southwest Ledges These make an area of roughly circular form with a diameter of some 6 miles, and whose center lies about 4 miles SW. from the Southwest Head. Depths on the ledges vary from 9 to 22 fathoms, with soundings of 30 fathoms or more about them.
The ledges and their vicinity are spawning grounds for herring, and netting is carried on here in June, July, and August.
