OBJECTIVE ; Quantify the year-round instream flow require- 

 ments for game fish in the upper Clark Fork River and prepare 

 an application to the Board of Natural Resources to reserve 

 these flows. 



DURATION: January 1984--completion of instream flow reserva- 

 tion 



CURRENT STATUS : Recreation, fish, wildlife and wetted 

 perimeter information has been collected on the upper Clark 

 Fork and its tributaries. Inflection points (minimum flows) 

 have been calculated for several stream reaches utilizing 

 wetted perimeter/stream discharge curves. 



Extensive fish population monitoring has been conducted 

 on all major tributary streams in the upper Clark Fork Basin. 

 As assessment of water quality needs for trout populations in 

 the mains tem has been prepared. 



During the extremely low flows of the summer of 1985,
