BIG TIMBER 



During the biennium the 

 management of the Big Timber 

 station has been changed over to 

 meet the requirements of fish- 

 ing in the area. With the co- 

 operation of the sportsmen, 

 what was formerly a concent- 

 rated brown trout rearing pro- 

 gram has been changed to rear- 

 ing rainbow trout for put-and- 

 take and for lake plantings 

 within the area. Brown trout 

 are still being raised, but on a restricted basis realizing from actual 

 samples and information derived from investigational programs that 

 the brown trout is very well established and at the present time 

 is in no need of assistance from an artificial program. The results 

 of this procedure will be analyzed annually. 



During the biennium the personnel have incubated and raised 

 golden trout which were secured from lake stock near West Yellow- 

 stone and are now all being held as brood stock at the Hamilton 

 hatchery where water is deemed most suitable for the propagation 

 of this species. These fish, when finally in production, will be 

 utilized in high elevation lakes where this species is well suited for 

 reproduction and survival. 



The Big Timber station incubates the eggs and rears the small 

 trout for transfer to the Bluewater station at Fromberg where they 

 are reared to legal size. The management of the Fromberg and Big 

 Timber stations is closely integrated. 



During the biennium the living quarters for the assistant fore- 

 man were completely repaired and put in top condition.
