Fishing Grounds of the Gulf of Maine
Cove of Jeffreys Ledge A small cove makes for a short distance into the western side of Jeffreys Ledge at about 20 miles from Boon Island in a SE. by S. ½ S. direction. The bottom in the cove is broken and muddy, with depths of about 60 fathoms. Thence, the ground slopes away to the mouth, where the edges about the entrance are rocky and have 70 and 75 fathom depths.
These rocky areas are cusk grounds in January, February, and March, during which months the cove itself usually furnishes good haddock fishing. Outside these depths the water deepens westward over a muddy bottom, where are from 80 to 90 and even 100 fathoms of water. Fishing here is mainly by trawl and gill nets.
A small shoal in the western part of the Cove of Jeffreys, having 50 fathoms over a bottom of blue clay and rocks and rising from the 60 and 70 fathom soundings about it, is about 1 ½ miles long by about 3/4 mile wide. This shoal is SSE. from Boon Island 15 miles. It is a winter ground for cod and haddock. Lying about SE. by S. ½ 5. from the Isle of Shoals 20 miles, 13 miles S. by W. from the whistling buoy on Jeffreys, and 43 miles S. by W. from Cape Elizabeth is a broken piece of bottom having from 75 to 85 fathoms of water over it, which is a haddock ground from January to April and a cusk and hake ground all the year.
