 LJ Spavntlng locations 



Lower reach WSCT spawned primarily in the North Fork of the Blackfoot River 

 and two tributaries to the North Fork (Dry Fork and Cabin Creek) (n = 6), but also 

 utilized Wales Creek (n = 3) and Arrastra Creek (n = 2). Arrastra Creek, the only 

 tributary between rm 67.8 and 88.8. captured 64% of middle reach WSCT (n = 7) 

 tributary use. WSCT telemetered in the middle reach also utilized upper Willow Creek (n 

 = 2), the North Fork (n = 1) and Sauerkraut Creek (n = 1). WSCT captured in the upper 

 reach migrated to 

 Arrastra Creek (n = 1), -xl^ 



Copper Creek (n = 1), the 

 Landers Fork (n = 1) and 

 Hogum Creek (n = 1), 

 but he majority (n = 3) 

 spawned in upper Willow 

 Creek, of which two were 

 repeat spawners (5 

 spawning events total). 



All telemetered 

 bull trout migrated, with 

 nine of 10 ascending 

 spawning streams and 

 one non-spavming fish 

 ascending a spring creek 

 tributary near Lincoln. 

 Total pre-spawning 



movements for bull trout 

 spavming in Copper 

 Creek averaged 42 rm 

 (range 27.9-66.8) 



between capture and 

 spawning sites, compared 

 with 43.9 rm (range 25.5- 

 100.9) for bull trout 

 spawning in the North 

 Fork. One bull trout 

 swam up-river from 

 Nevada Creek to Lincoln 

 before returning down- 

 river to ascend the North 

 Fork, a total distance of 

 101 miles. Bull trout 

 from all three reaches 

 spawned in Copper 



Creek, while North Fork bull trout migrated from the lower and middle reaches of the 

 Blackfoot River. The only non-spawning bull trout moved from its capture location near 

 Lincoln Gulch into Keep Cool Creek on April 26, 2003, presumably for refuge from high
