for brown troul but Ihc bilter is so warm that it is not believed 

 any great number of trout could survive. The Fredonia reservoir 

 on tributary 7, however, contains adult rainbows and the stream 

 itself above appears large enougli for natural spawning. 



ChduUuKjud Creek ^System: Except for tributary 9 and an oc- 

 casional spring-run altogether too small for fishing, there is no 

 place suitable for brook trout. However, brown trout have been 

 taken in several parts of the main stream and large rainbows have 

 been reported in early spring. The only possible barrier to the up- 

 ward migration of rainbows from Lake Erie is a falls of about 21/2 

 feet situated in the lower section. It is believed that rainbows may 

 successfully pass this falls and hence an attempt to establish a run 

 has been suggested. Tributary 19, Clarks brook, is small but 

 nevertheless large enough- to provide some brook trout fishing and 

 since it is the only stream in the watershed in wdiich brook trout 

 may be expected to survive, this si)ecies has been assigned. Should 

 local fishermen however i)refer to reserve this as a nursery stream 

 for browns no serious objection should be made. 



Twentymile Creek System: This system is much like the Chau- 

 tauqua having Avater too Avarm for brook trout except an occas- 

 sional spring fed tributary much too small for fishing. Brown and 

 rainbow trout, however, occur at several points and there is a pos- 

 sil)ility of establishing a comparatively large run from Lake Erie. 

 The only fall is a low one about 18 inches high situated in the 

 lower section which could readily be ])assed by rainbows during 

 the period of high water in A])ril and ^lay. 



Bass Waters: St)'eanis: Large or small mouthed bass have been 

 I'ccommended for all unpolluted streams over about 30 feet wide in 

 which natural spawning is apparently inadequate. We have elimin- 

 ated the lower sections of streams which may be entered by bass 

 l)reeders from Lake Erie because, if entirely suitable, they should 

 be fully ])opulated with young from lake breeders. If they are not 

 so ])oi)ulated, it is reasonable to presume that they are not suitable 

 in which case, stocking would be unsuccessful. Two noteworthy ex- 

 ami)les are Buffalo and Cattaraugus creeks. At one time the latter 

 as far u))stream as Gowanda, must have been an enormous natural 

 hatchery for Lake Erie bass. This is borne out by the statements 

 of the older inhabitants of the region. The present polluted con- 

 dition, though it may not wholly ])revent bass from entering, must 

 o])('i"at(' advei-sely ui)on eggs and young. 



Streams under 'M) feet in Avidlli, ii' they contain bass at all, 

 usually are oxer populated Avith undersized fish, the result of 

 natui-al s))awning. M is e\ident that nothing would be gained by 

 stocking them. 



Small-mouthed bass have been reeommended for streams with 

 some current and lia\ing freipienf gravel shoals; lai-ge-mouthed, 

 I'oi- the more sluggish streams with mud bottom and an abundance 

 ot" \-egetation part ieidai'ly water lilies and cattails.
