TITLE OF STUDY ; Western Montana Fishery Investigation, Inven- 

 tories and Surveys of the Upper Clark Fork River (above Drummofid) 



CONTACT ( S ) ; Dennis Workman - Montana Department of Fish, Wild- 

 life and Parks, Missoula - 721-5808

OBJECTIVE ; Evaluate the condition, distribution and abundance 

 of trout in the upper Clark Fork drainage. 



DURATION ; 1969 - Indefinite 



CURRENT STATUS ; Trout population estimates have been conducted 

 on the upper Clark Fork River at the following locations; 



pH Shack (near Warm Springs) 1969 - present 



Sager Lane (near Dempsey) 1981 - 1982 



Williams-Tavener (below Deer Lodge) 1969 - present 



Phosphate (below the Little Blackfoot 1978 - present 

 River 



Brown trout movement (numbered T-tag) and recruitment studies 

 have also been conducted near these stations. 



Trout populations have been estimated for several years 

 on the following tributaries: Warm Springs Creek, Gold Creek, 

 Flint Creek and the Little Blackfoot River. Fishery 

 surveys have also been routinely conducted on Racetrack Creek, 

 Lost Creek and Dempsey Creek to help determine their importance 

 as sources of recruitment to the upper river. Trout populations 

 in several other tributaries of the study area have also been 

 recently monitored as part of the instream flow reservation stud- 

 ies. 



FUTURE ACTIVITIES ; During the 1987 field season, electrof ishing 

 surveys will be conducted from Warm Springs Ponds to the Milltown 

 Reservoir. This extensive survey will provide an excellent de- 

 scription of the composition and distribution of fish populations 

 and their relationship to habitat conditions.
