OBJECTIVE : Quantify the status of the trout fishery in the middle 

 portion of the Clark Fork River (from the confluence of the Black- 

 foot River to the Flathead River) relative to present and pro- 

 jected water quality, habitat and instream flow conditions. 



DURATION; 



1983 - 1987 



CURRENT STATUS ; Trout population estimates have been conducted 

 at sections below Milltown, above the Bitterroot River and near 

 Superior. Brown trout spawning site surveys have been conducted 

 in the autumn. Trout movement data has been generated using 

 jaw tagging at the Superior section. 



FUTURE ACTIVITIES ; Fish population estimates will continue to 

 be collected at all sections. Wetted perimeter transects will 

 be established at several locations along the river to allow 

 determination of instream flow requirements for game fish. Ad- 

 ditional spawning and trout movement surveys will be conducted.
