FISHES OF THE CONNECTICUT LAKES. 9 



nearer the point of entrance of Main Inlet, the more gradual the slope, 

 due to the deposit of silt in freshet time. The depth in the immedi- 

 ate vicinity of the entrance is 4 to G feet, and a large part of this 

 region ranges from 40 to 50 feet in depth. Around the shores of this 

 lake there was no shallow littoral bench or shelf such as existed in the 

 other lakes and ponds visited, but a fairly uniform descent to the 

 deeper waters. 



The offshore body of water is generally pretty deep. The deepest 

 place found by numerous soundings was 140 feet, about three-fourths 

 of a mile southeastward from Metallak Point and less than one-fourth 

 mile northeastward of G-reens Point, which is a little east of south of 

 Metallak Point, near the entrance to South Bay. About halfway 

 from Abbott Point to Stony Point there is a dej)th of 70 feet, toward 

 the latter point shoaling to 50, then increasing to TO feet again about 

 one-fourth of a mile off the point. Off Abbott Point it rapidly 

 deepens to 35 feet, and about halfway between this point and Metallak 

 Point there is a depth of 70 feet. 



South Bay has deep water over most of its area and generally close 

 to shore. The greatest depth is 130 feet, almost midway between the 

 shores and directly west of Stony Point, and 120 feet is found farther 

 down the bay, and 100 feet over half a mile from the entrance. The 

 greater depths are found nearer the west than the east shore. The 

 depth of West Bay decreases from about 88 feet off Metallak Point 

 to 79 or 80 feet about three-fourths of a mile farther west, thence 

 rapidly shoals to the outlet.* 



The fishes found near the lake in the small affluents are considered 

 here as a part of the lake fauna. The following is a list of the 

 species collected by us in these places and in the lake : 



Longnose sucker {Catostoinus v(tlostomus). 



Common sucker (Catostomiis coiuinersonii). 



Chub (ScmotiJus buUaris). 



Keclfin {Notropis coriuitiis). 



I.onguose dace {Rhinichthys cataracta;). 



Blacknose dace (Rhinichthys atronasus). 



Chub-minnow (Couesius plumbeus). 



Eel (Anguilla chrisypa). 



Brown trout (Sal mo fario). 



Trout (SalreJinus fontinalis). 



Blob (Cottus gracilis). 



Burbot (Lota maculosa). 



Of these, chubs and chub-minnows appeared to be the most abun- 

 dant ; small blobs were common ; cusk and eels doubtless numerous 

 enough; suckers of two kinds plentiful; redfins not numerous, and 

 neither of the two kinds of dace very abundant. It could not be de-

 given in Mr. Doolittle's section of this rei)ort.
