15.2 fish/1000' (Figure 14). Densities of native bull trout (> 6.0") increased from 4.3 to 



6.1 fish/1000' (Figure 14). The 2002 point estimate for brown trout (> 6.0") remained 



stafic at 20.1 compared with 19.1 fish/ 1000' in 2000 (Figure 14). 



In 2002, we observed two

Scotty Brown Bridge Section 



The 2002 percent trout 

 composition for the total catch in 

 the Scotty Brown Bridge section 

 was 38.7% rainbow trout (n=276), 

 31.5% brown trout (n=225), 

 23.0% WSCT (n=164), 6.7 % bull 

 trout (n=48) and 0. 1 % brook trout 

 (n=l). Total trout (fish >6.0") 

 densities decreased -8% from 98 

 to 90 fish/1000' between 2000 

 and 2002. 



Densities of smaller 

 rainbow trout (4.0 - 10.9") 

 decreased from 25.1 to 12.7 

 fish/ 1000' between 2000 and 

 2002. Rainbow trout in the 

 intermediate (11.0 - 13.9") class 

 also decreased from 8.2 to 6.2 

 fish/1000'. Densities of large 

 rainbow trout however (fish 

 >14.0") increased from 9.2 to 24.5 

 fish/1000' (Figure 16). 



The point estimate for 

 brown trout (>6.0") was stafic 

 with 24.1 fish/ 1000' in 2000 

 compared with 23.8/1000' in 

 2003 (Figure 15). 



Estimated bull trout 

 densities (fish >6.0") decreased 

 from 7.7 to 5.1 fish/1000' 

 between 2000 and 2002. WSCT 

 densifies (fish >6.0") also 

 decreased from 23.0 to 20.3 

 fish/ 1000' between 2000 and 

 2002 (Figure 15).
