Oquossoc Lake is about 5)/^ miles in a direct line in its long axis from the east to 

 west end. The Greenvale and Outlet Coves are the longest two, each about i J^ miles, 

 making the extreme length of the lake approximately a little over 8 miles. Its greatest 

 width directly north from just east of South Cove is nearly 2 miles, and the narrowest 

 place at right angles to the east and west axis is about four-fifths of a mile, northward 

 from Long Point to just west of Mingo Springs; that is, about i^ miles from the west end 

 of the lake. The Maine Water Storage Commission gives its average high-water eleva- 

 tion above the sea as 1,577.2 feet and its area as 9.76 square miles. The greatest depth, 

 145 feet, is in the upper end, about three-fourths of a mile northward and westward 

 from Greenvale Cove or directly north by compass from Haines Point, the western limit 

 of Greenvale Cove. Greenvale Cove is 60 to 94 feet deep near its entrance, shoaling 

 gradually to the head of the cove. South Bog Cove carries 14 to 30 feet in its deepest 

 water. The mid lake carries from 50 to over 100 feet as far west, at least, as a line 

 northward from South Bog Islands. Thence it shoals irregularly northwestward to the 

 outlet. 



The storage is controlled by a crib dam of the open-weir type, over which the water 

 seldom, if ever, flows. The right-hand half of the dam is occupied by the usual log 

 sluicing gates, housed over. The elevation of the sill is 60.65 f^^t above the sill of the 

 dam at the foot of Mooselucmaguntic Lake, giving the outlet, Rangeley stream, a con- 

 siderable current in its 2.6 miles course to the lake below. The stored water of this 

 lake, some 2,584,328,000 cubic feet, is usually the last to be drawn upon, and hence 

 high level is usually maintained through the summer tourist season. 



The principal tributary waters are as follows: Northeast of Rangeley Village is 

 Gull Pond, having an area of 0.75 square mile and being about iX miles long by five- 

 eighths of a mile wide, which discharges its water into Haleys Pond through a stream 

 about three-fourths of a mile in length. Haleys Pond is approximately three-fourths 

 by one-half of a mile in its greatest diameter and has a depth of 7 to 17 feet, the deepest 

 water being at the upper end. It is separated from Oquossoc Lake by a dam and short 

 stream only, which empty into Rangeley Cove. The northern affluents are: Round 

 Pond, about one-half by less than one-fourth of a mile, connected by a short stream 

 with Dodge Pond, which is i^ miles long by a little over one-fourth of a mile wide 

 and empties int'o Hunter Cove through Dodge, or Collins Brook, something over i mile 

 in length. The deepest water of Dodge Pond is at the outlet end, where it is 40 feet, 

 but it carries a depth of 35 feet to near the upper end. About one-fourth of a mile from 

 Dodge Pond another stream from Quimby Pond joins Dodge Brook. Quimby Pond, 

 with an area of 0.27 square mile, is about three-fourths by one-half of a mile in 

 extreme diameters and its outlet about i}4 miles in length. There are several other 

 brooks from diminutive ponds or none on the north shore, but they are of no conse- 

 quence so far as this report is concerned. Flowing into the extreme end of Greenvale 

 Cove is Niles Brook from the eastward and Long Pond Brook, conveying the waters of 

 Long Pond and its tributary brooks. Long Pond is about i^ miles long and three- 

 fourths of a mile in its southern diameter. The distance from Long Pond to the lake 

 by the outlet is about ij^ miles. There are several brooks tributary to Long Pond, 

 one of which comes from a small pond something over 2)4 miles to the south west ward, 

 and Long Pond is not over one-half of a mile in a direct line from the headwaters of a 

 branch of Sandy River, a tributary of the Kennebec. Several minor brooks empty
