Rock Cod Ledge.  This ledge lies NE. of Seal Island 1 mile.  It has a depth of 3 1/2 fathoms on the shoalest part, deepening gradually on all sides for a considerable distance.  The bottom is of sharp rocks and is broken in places.  Rock cod area present in fair numbers in spring and fall, and this is a mackerel and herring ground in their seasons.  Haddock are abundant in the fall close in to the rocks of Seal Island in 6 to 15 fathoms.  This is not a hake ground, although there are a few cusk to be had here on the deeper parts and an occasional small halibut is taken in the kelp on the shoal in June and July.  It is a good lobster ground.

Gravel Bottom and Southeast Ground.  These lie S. of Seal Island. forming an extensive piece of fairly level ground extensive piece of fairly level ground.  The western that bears a little E. of S. and the eastern part about ESE. from the island.  It is about 5 or 10 miles in diameter.  While this is really but one piece of ground, the eastern part is called the Southeast Ground and the western part, from the nature of its bottom.

The Gravel Bottom.  The eastern portion is muddy and has 40 to 60 fathoms.  The western has 35 to 40 fathoms.  It is a good cod ground in winter and spring.  Haddock are present from November to March, inclusive; hake in summer.  Fishing is done mainly by trawling by sloops and vessels.

Laisdells Ground.  This is a small, rocky spot outside the Brandy Ledges.  It is about 1/4 acre in extent and has a sharp rocky bottom with 20 fathoms of water over it.  It is the best cod and haddock ground in Isle au Haute Bay.  This is chiefly a small boat ground and is also a lobster ground.

Saddleback Reef.  This reef lies S. from Saddle-back Ledge, 3/4 mile distant.  It is about 2/3 mile long N and S by 1/4 mile wide.  Depths are from 15 to 35 fathoms over a broken and rocky bottom.  Cod are taken here by hand line in May and June; haddock and cod by trawling in fall and winter (November to January 1).  It is a good lobster ground and chiefly a small-boat ground.

Otter Island Reef; Snipper Shin; Western Reef.  These are names applied to different sections of an irregular, broken piece of rocky ground about halfway between Vinalhaven and Seal Island.  Otter Island Reef is the eastern section, lying 4 miles W. by S. by 1/4 S. from the western head of Isle au Haute.  Depths here are from 10 to 25 fathoms over a rocky bottom.  The trawl, formerly not much used here, is now in general use.  This is a cod and haddock ground at seasons when these fish are in shoal water, but it is best for cod in winter and spring and for haddock in the fall, from November 1 to January 1.

Old Ripper.  This lies S. from the Western Ground (Western Reef) and 10 miles WSW. from Criehaven or Ragged Island.  Apparently this is a part of the Western Ground.  On the deep-water mud bottom between these (Ripper and Western Reef) is good hake fishing in summer, and cusk are abundant from May to the time when the dogfish strike the ground, usually about July 5 to 10.
