Fishing Grounds of the Gulf of Maine.
Barnum Head Grounds.These lie SSE. from Damariscove Island and are about 1 mile long by 400 yards wide. Depths are from 40 to 70 fathoms over broken ground of sharp rocks on the shoals, with mud on the deeper parts. This ground is fished by hand lines, gill nets, and trawls mainly by boats and small craft.
Cod, haddock, and pollock are found here in the spring and fall months: hake in the muddy parts in summer. It is a summer hand-line ground for cod and pollock also.
Marks: Bring the peak of Heron Island on Damariscove and the "Whistler" on Seguin, 7 miles from Damariscove Island (this gives 21-fathom soundings) or Big White Island's inner part just touching on Barnum Head; Morse Mountain (in Kennebec) touching on eastern part of Seguin to make a sawtooth.
