(1 and 2 ft). Using WSP predicted flows for riffle transects, the flows at 

 these depths range from 6.8 to 17 m^/sec (240 to 600 cfs). Using 75 percent 

 of optimum, a minimum rearing flow recommendation of 5 mVsec (180 cfs) is 

 obtained. 



MONTHLY INSTREAM FLOW REQUIREMENTS 



Recomnended minimum instream flows shown in figure 28 are the flows 

 necessary for the species with the highest requirements for each month. 



While the instream flows presented for each life history stage and each 

 species are 75 percent of the optimum value, a flow was not recommended 

 unless judged to be an adequate flow. Professional experience was utilized 

 as a basis for determining if a flow was adequate.
