See hydro graph below. The summer instream flow <br />recommendation was reduced to 4.5 cfs (8/1-10/31) based on the water availability analysis. As <br />per the Division 2 Engineer, senior water rights do not present a water availability problem <br />within this reach of stream. <br /> <br />(Water Yr) <br />(1992-93) <br />(1992-97) <br /> <br />OCT <br />14. <br />13. <br /> <br />NOV <br />6.6 <br />7.3 <br /> <br />MEDIAN MONTHLY FLOWS cfs <br />DEC JAN FEB MAR APR MAY JUN <br />5.9 6.3 6.3 7.2 14. 21. 24. <br />5.5 5.5 5.1 6.7 13. 26. 41. <br /> <br />JUL <br />8.5 <br />14. <br /> <br />AUG <br />4.1 <br />13. <br /> <br />SEP <br />4.2 <br />12. <br /> <br />FOURMILE CREEK #2 <br />% of Gage #07096250 <br /> <br /> 14.00 <br /> 12.00 <br /> 10.00 <br />~ 8.00 <br />U 6.00 <br /> 4.00 <br /> 2.00 <br /> 0.00 <br /> ") <br /> <br />-------. <br /> <br /> <br /> <br /> <br />- ---- -- <br /> <br />")") ~ ~ ~~ ~ ~~~")")")")") ~ ~c., c., 0 0 """"~ <br />MONTH <br /> <br />1-1992-93 _ _ _ .1992-97 - -Instream Flow I <br /> <br />. <br /> <br />Div 2 Rec Sum Rpt <br />
