A few of the Cazenovia tributaries are cold enough for brook 

 trout but with the exception of one, they are too small to be 

 considered as fishing streams and since Cazenovia proper is not a 

 trout stream, we have not indicated a stocking policy for the 

 smallest cold tributaries. The exception to this is Spring brook, 

 7/ which is not only cold but large enough to support some fishing. 

 Brook trout have thus been recommended. 



Almost all of the other tributaries of Buffalo creek suitable for 

 trout are small and comparatively short. There are two however, 

 55^ (Beaver Meadow) and 58,' which afford several miles of fish- 

 ing. In the former, Angel Falls about 30 feet high and located 

 just above Java Village, divides the stream into a colder section 

 above and a warmer one below. The upper part is spring fed and 

 temperatures run well below the critical point for brook trout. 

 On August 9 between 10 :30 and 11 :30 temperatures ran as follows : 

 Station 1, air 80.5, water, 59 ; Station 2, air, 80, water 63.5. In 

 the Avarmer part just below the falls the following temperatures 

 were recorded at 4:30 p. m. on the same day: Air, 84.5, water, 75. 

 Brook trout should be planted above the falls and brown trout 

 always below. 



Beaver Meadow creek is the outstanding brook trout stream in 

 the Buffalo creek system, and is worthy of heavy and continuous 

 stocking. TributarA^ 58 is considerably warmer and although cer- 

 tain pools now contain brook trout, it is believed to be better 

 adapted to browns. Temperatures taken from 12 :45 to 2 :30 p. m. 

 on August 9 ran as follows: Station (1) air, 83, water, 74.5; (2) 

 air, 84, water, 76; (3) air, 84, water, 78.5. 



Eighteenmile Creek System: There are about 7 miles from 

 Boston to source in \vhich both brown and rainbow^ trout were 

 observed. Possibly the uppermost mile might be suitable for brook 

 trout, but it would hardly seem wise to reserve so short a section 

 for this species. The most important tributary is the South 

 Branch, 4. Above New Oregon, it is well adapted to brown trout. 

 Also in accordance with the new policy for rainbows, fingerlings 

 of this species should be spread over the upper 8 miles. Tributary 

 29, however, which is large enough for fishing and much colder 

 than the main stream, should be reserved for brook trout. Among 

 the other tributaries of Eighteenmile creek, 14 showed tempera- 

 tures just under the critical point for brook trout. Since it is too 

 small for fishing and does not flow into a section of the main 

 stream suitable even for brown trout, stocking is not advised. All 

 other cold tributaries entering the main tream above Boston 

 should receive brown trout. They are principally feeders for the 

 mam stream. 



Sister Creek System: Here we found but a few miles in the 

 headwaters and but one tributary, 14, in which brown trout con- 

 ditions seemed to prevail. Ilankinson records tw^o specimens of
