re-orientation, followed by a decrease in movement as the 

 winter progressed. In contrast, Logan (1961) reported that 

 the movements of rainbow trout in Bridger Creek, Montana, 

 appeared to be slightly greater in December, January and 

 February when the temperatures were low and surface ice was 

 present. Much of the movement reported by Logan was highly 

 localized as indicated by the fact that, during the 10-month 

 study, over half of all tagged trout found in the 900 foot 

 long study section were recovered within 150 feet of their 

 initial place of capture. 



Habitat Selection in Winter 



Needham and Jones (1959) observed that rainbow and brook 

 trout in Sagehen Creek, California, were in close proximity 

 to shelter during winter daylight hours. Shelter consisted 

 of overhanging bushes, projecting snow banks, and a deep 

 sheltered pool protected by exposed roots. Trout were more 

 numerous in shallow water during the night than during the 

 day. 



Cooper (1953), working on brook trout streams in Michigan, 

 reported that in spring, summer and fall trout were found in 

 pools, riffles or near cover within the main stream. These 

 habitats were completely deserted during winter, when the 

 trout were found only in low velocity areas under banks, in 

 piles of stones and rocks or amid heavy accumulations of 

 brush and debris.
