four-fifths- of a mile long and half as wide in its broadest diameter, is one-fifth of a mile 

 at its southeast end from the east shore or broad cape south of Bugle Cove. 



The other important island of the lake is Toothakers, previously referred to, the 

 northwest end of which is sHghtly over i mile from Students Island and the southeast 

 end about iX miles from Bemis Station. It is irregularly elliptical in shape, about 

 if miles long by nearly four-fifths of a mile wide in its greatest diameters. 



Pleasant Islands, famous as the location of a sportsmen's camp and unimportant 

 for any other reason, are situated about 3 miles in a direct line up Cupsuptic Lake from 

 Haines Landing. A group of small islands, known as Browns Islands, just above the 

 entrance to Cupsuptic Lake, are nearly 1% miles from Haines Landing. There are 

 other small islands in Mooselucmaguntic Lake, particularly in Wildvvood Camps Cove 

 and the cove just north of it. At a number of places shoals occur, where the depth 

 is only a few feet at high water and which appear as islands at low water. 



The altitude of Mooselucmaguntic at high water is 1,472.4 feet, and its area, includ- 

 ing Cupsuptic Lake, is 28.27 square miles. 



On the east and west portions of the lake the deepest part is found south from the 

 west end of Students Island, where it is 100 feet. The average depth for quite an area 

 is probably about 50 feet. East of Toothakers Island the maximum depth is from 30 

 to 35 feet, and the deepest part of the lake is in Bugle Cove, where a depth of 124 feet 

 is found about 2^ miles northeastward of the northwest end of Students Island. Cup- 

 suptic Lake is very shallow above Pleasant Islands, but below this point the deeper 

 waters carry 50 and 60 feet. 



Upper Dam at the outlet, the height of which during the last 10 years or so has 

 been increased to the level of the land on the south shore of the lake, controls the storage 

 of the lake, giving it at high water 10,002,039,000 cubic feet. The dam is about 200 feet 

 between abutments. A dike extends from each abutment to the higher land beyond; 

 that in the southeast being nearly a mile in length, mostly of artificial construction. 

 The sill of the dam is 18.03 feet above that of Middle Dam at the foot of Wellekenneba- 

 cook. The original bar that formed the dam for the natural lake is about one-half 

 mile above the present dam, and if the gates at the dam are opened a sufficient amount 

 the water in the pool between this bar and the dam is drawn down to a point below the 

 water in the lake. 



The shores are irregular, with points and bays both large and small. The greater 

 part of the shore is covered with driftwood and "dry khi," in some of the low places for 

 one-fourth of a mile. This is particularly true of the portion about Cupsuptic Lake. 

 The greater part of the shore line is wooded, being covered with second-growth timber, 

 both hard and soft. 



There is but little lowland bordering the lake, this being found at the eastern 

 extremity near Bemis Stream and a small area near Upper Dam. There is also lowland 

 on the east around the entrance of Kennebago and Rangeley Streams and at the upper 

 end of Cupsuptic Lake. With the exception of these low places the land gradually 

 rises, the 5-foot contour being from 50 to 100 feet back, on the average, and the lo-foot 

 contour about 150 feet. 



The principal tributaries of Mooselucmaguntic Lake are Cupsuptic and Kennebago 

 Rivers and Rangeley Stream in the northern part of the lake and Bemis Brook at the 

 southern end. There are a number of other small brooks flowing into the lake at 

 various places.
