mend this species for the larger streams and lakes showing warm, 

 clear w^hite water with abundant shoals of clean gravel or rocks. 



The principal small-mouthed bass waters are the Genesee river 

 from Belmont to Rochester, Honeoye creek from Honeoye Falls 

 to Rush and Conesus lake. 



Large=Mouthed Bass, Bluegill Sunfish, and Catfish Waters. — 

 These three species will be found chiefly in warm streams and 

 lakes showing the following conditions: Brown or white water; 

 very sluggish or totally stagnant; a bottom of mud, silt or sand ; 

 and an abundance of vegetation, particularly water lilies, cattails 

 and other emergent types. 



The principal waters suitable for these three species are Silver 

 and Honeoye lakes; Black creek with Horseshoe lake, Godfrey's 

 and Bj^ron ponds (Map 1) ; Round and Long ])onds (Map 2) ; 

 Black creek, Flannagan's pond and Rockville reservoir (Map 4). 



P5ke=Perch Waters. — Pike-perch a])])arently thrive in a great 

 variety of situations and have been more or less successfully intro- 

 duced into different types of lakes and streams. In the Genesee 

 watershed they are found in Conesus lake in depths up to 40 feet 

 on both sand and gravel bottom, where vegetation is dense and 

 where it is absent ; in Silver lake, having brownish water, sand 

 bottom and abundant vegetation, in shallow water and in depths 

 up to 30 feet ; in the Genesee river below Mt. Morris in shallow 

 water on sand, mud and gravel bottom where vegetation is sparse 

 or absent ; associated with small-mouthed bass in the Genesoe 

 river and Conesus lake and wdth large-mouthed bass in Silver lake. 



Until something more definite is known about their habitat pref- 

 erences, it is probably best to limit them to the waters mentioned 

 above. 



Two New Lakes. — In the ])ro))osed damming of the Genesee 

 river at Mt. Morris and its tributary, the Ganeadea creek at 

 Ganeadea, two new lakes are to be formed which Avill increase 

 materially the area available for fishing. 



The first lake will extend some sixteen miles up the valley from 

 the proposed dam at Mt. Morris to the lower falls of the Genesee 

 river in Letchworth Park. It will vary in width from one-fourth 

 to one mile and will have a maximum depth of about 192 feet. 



The water level will fluctuate widely during the year, due partly 

 to the drawing of water for industrial i^urposes. This will tend 

 to eliminate all shoal water at certain seasons and should these 

 periods come in late fall and during the spring months as antici- 

 l)atecl, the natural spawning of fishes will be seriously interfered 

 with. The principal source of stock fish will have to come from 

 annual plantings of hatchery fish. There may be some natural 

 stocking wdth small-mouthed bass, due to a dow^nstream movement 

 from the Genesee river above Portageville, but the presence n 

 impassable falls just above the lake will prevent the upward 

 migration of all species from lake to river.
