OBJECTIVE : Determine the relative importance of tributaries 

 as existing or potential sources of recruitment for trout 

 populations of the middle Clark Fork River (between the 

 Blackfoot and Flathead Rivers). 



DURATION ; July 1984 - July 1986 



CURRENT STATUS ; Fishery surveys are being conducted on all 

 perennial tributaries (approximately 25 streams) to determine 

 their potential importance for providing recruitment of 

 rainbow, brown cutthroat and bull trout to the mains tem of 

 the Clark Fork River. Photographic stations have been 

 established on several streams to record habitat changes 

 with different flow volumes. 



FUTURE ACTIVITIES ; Instream flow requirements for migrant 

 and resident fish will be determined. Factors which may be 

 negatively affecting the fishery (barriers which may hinder 

 or block migrant fish passage, water quality problems, 

 etc.) will be assessed. A management plan will be formulated 

 to maintain and improve the fishery values of tributary 

 streams. A progress report on these activities will be
