V. Vegetation of Silver Lake and Conesus Lake 



By W. C. MUENSCHER, 



Assistant Professor of Botany, Cornell University 

 The writer and Mr. P. R. Burkholder visited Silver lake in the 

 latter part of August and Conesus lake in early September, 1926, 

 for the purpose of making- a study of the plant life of these lakes 

 as a i)art of the biological survey of the Genesee river system. 

 The time available, about two weeks, was altogether too short to 

 investigate all the ])roblems of plant life that might have a bearing 

 upon the fish i)opulation of these lakes. During the time that was 

 spent at these lakes data were obtained respecting (1) the dis- 

 tribution of the larger aquatic plants in both lakes, (2) the distri- 

 bution of the bottom fauna and flora in both lakes, (3) the quan- 

 tity and vertical distribution of the plankton in Silver lake, 

 (4) the transparency of the water of Silver lake. 



Silver Lake. — Silver lake, in Wyoming county, lies in a shallow 

 valley witli very gradual slopes. The surrounding hills rise only 

 a few hundred feet above the lake, which is 1,'V)G feet above sea 

 level. The lake is about three miles long and about three-fourths 

 of a mile wide in the widest place. Its shores are mostly stony 

 or gravelly, except that at the north and south ends, where swamps 

 occur, the shore and bottom are muddy. The lake is fed by 

 S|)rings. A small inlet and the outlet of Silver lake both occur 

 at the nortli end. 



The lake is shallow and the fiat bottom is mostly about 25-35 

 feet deej). Tiu' deepest bottom found in the lake (Fig. 9) was 

 37 feet. The transparency of the water in Silver lake is low as 

 compared with Conesns hike and may be termed "brown water."
