Map 5. Lake Como covering about 52 acres is well adapted 

 to rainbow trout but now contains both rainbow and brook trout 

 in addition to a mixed population of bass, sunfish, perch, etc. The 

 maximum depth is about 20 feet and when examined July 19, 

 showed a bottom temperature of 64 and a surface temperature of 

 76 with a maximum air temperature on this clay of 77 Fahr. 

 Both the inlet and outlet contain brook trout. The latter in addi- 

 tion has been stocked with browns and rainbows. 



Map 6. The Potters falls reservoir is the only public pond in 

 this area suitable for trout, It is formed by a dam in Sixmile 

 creek approximately 60 feet high just east of the city of Ithaca and 

 covers an area of about 192 acres. At the present time the maxi- 

 mum depth is about 47 feet and the average depth about 20 feet. 

 The bottom is covered with mud, sand and gravel, the first pre- 

 dominating. On July 11 at 5 P. M. the following temperatures 

 were recorded : Air, 87 ; water at the surface, 80 ; water at a depth 

 of 38 feet, 58° Fahr. In the past Sixmile creek has been stocked 

 with rainbow trout which have migrated downstream, principally 

 during the second year, into the reservoir where a good many 

 have apparently matured. This is proved by the capture during 

 the past two or three seasons of adults in spawning condition in 

 various sections of Sixmile up to the first dam at Brookton. 



The recently constructed settling basin about one-fourth of a 

 mile above the reservoir will hereafter act as a barrier to move- 

 ment further upstream. However, between the basin and the res- 

 ervoir, the stream is rapid with gravel and rubble bottom and will, 

 it is believed, supply a sufficient spawning area for trout. The 

 settling basin itself is a pond of several acres and may also prove to 

 be a stopping place for rainbows. Since the stream and reservoir 

 are apparently rich in food, they can stand a very heavy annual 

 plant, 



Warm Water Ponds and Lakes 



There are approximately 6,447 acres of warm water ponds and 

 lakes. The ratio of small-mouthed bass to large-mouthed bass areas 

 is a little less than one to two. The largest bass areas are to be 

 found in the lower regions, Maps 2, 3A, 4A and 4B. There are no 

 warm ponds in Maps 1, 6 and 7.. 



Eleven of the ponds or lakes contain 160 acres or more. Only 

 two of these, namely, Cross and Cazenovia lakes, show conditions 

 favorable to small-mouthed bass. The others are shallow, warm, 

 often with brown water, mud bottom and with large areas covered 

 with vegetation both submerged and emergent types, constituting 

 ideal conditions for large-mouthed bass, bluegills and bullheads. 



Cross lake is the largest of the group and shows diverse condi- 

 tions. All types of bottom are present, the vegetation is luxuriant 

 and the food richness is high. It has always been an exceedingly 

 productive body of water and a popular one for fishermen. The 

 principal food varieties are the large and small-mouthed bass,
