Fish wiers have been established on the Jocko River and 

 Mission Creek to assess spawning runs of trout from the main 

 river. Annual progress reports for 1983, 1984 and 1985 are 

 available from the CSKT's office in Pablo. 



FUTURE ACTIVITIES ; Preliminary findings indicate a lack of 

 successful spawning by trout species in the lower Flathead 

 river. Field studies as outlined above will continue. 

 Instreeim flow determinations will be conducted on the 

 mainstem during the autumn of 1985, utilizing the Instream 

 Flow Incremental Methodology. Progress reports will be 

 prepared for work conducted during 1986. By 1987, an array 

 of fishery management options will be prepared to mitigate 

 the impacts of present hydroelectric operations (demonstrat- 

 ing under each option how fish populations and hydroelectric 

 generation capabilities would be modified) .
