Results 



Summary metrics of all McNeil core samples by total stream sample, including 

 survival at emergence calculations for WSCT and bull trout are located in Table 14. 

 Summary results (all streams) of two metrics of central tendency (Fredle index and 

 geometric mean), ranked in ascending order by Fredle index are presented in Figure 56. 

 Summary results (all stream) for two percent metrics of "fine" sediment (<0.84mm and 

 <6.35mm), ranked in ascending order by the sample mean (<0.84mm), are located in 

 Figure 57. 



Existing bull trout spawning sites had significantly lower percent fines 

 (P=0.0004), significantly higher geometric means (P=0.0004) and Fredle indices 

 (P=0.0001) than the spring creeks (Table 15). We also tested individual spring creeks 

 against the combined bull trout spawning locations. Rock Creek and Kleinschmidt were 

 significantly different fi-om the bull trout spawning sites when tested against the three 

 variables (Table 1 5), whereas Nevada Spring Creek did not have a significantly different
