Fishing Grounds of the Gulf of Maine
Deckers Shoal, Middle Shoal, Pollock Rip and Allens Shoal These are small rocky patches lying to eastward of Monhegan Island and northerly from the Outer Shoal. They have depths from 6 to 30 fathoms over a sharp, rocky, and broken bottom. Middle Shoal is 2 miles from the island. Pollock Rip 1 1/2 miles. Allens Shoal 1 1/4 miles, having 5 1/2 fathoms and breaking in rough weather; and Deckers Shoal 1 mile. Depths vary here from 6 to 30 fathoms over a bottom generally sharp and rocky.
The principal fishing here is hand-lining for cod in the spring during the herring season and in the fall in "squid time". A few pollock are taken here also.
A number of small patches lie westerly from the Outer Shoal and close to Monhegan Island. These are the Cusk Ground with a depth of 20 to 35 fathoms; Gull Rock Ledge (breaks in rough weather) 3 1/2 fathoms; Lobster Point Ground, 15 to 30 fathoms; Inner Spring Ground, 15 to 30 fathoms; Outer Spring Ground 25 to 30 fathoms.
All these are fished for cod nearly all the year, for haddock in December and January, and for pollock in early spring and late fall. The Spring Grounds are near the harbor and so are fished before the others. All are lobster grounds. Small boats and vessels operate here.
