<br />. <br /> <br />. <br /> <br />USFWS - Palisade/Grand Junction Stream Flow Analyses - DRAFT <br />May 12,1995 <br />'Page 18 <br /> <br />released it creates a storm type hydrograph. The peak runoff of the hydrograph measured <br />at the 27.5' Mile Rd gage is flatter than that measured at the Palisade gage because of <br />channel routing, effects and temporary bank storage. This results in Palisade gage flows <br />being greater or nearly equal to the 27.5 Mile gage flows which includes the local inflow. <br />When the two gages have the same recorded flows the calculated local inflows go to zero. <br /> <br />Figure 9, shows the relationship in 1994 of the gaged stream flows, Grand Valley <br />irrigation diversions, and calculated local inflows. Local inflows can be seen to decrease <br />when Grand Valley Canal irrigation diversions are ceased on November 7, but return after <br />the river flows stabilize. According to Mr. Klapwyck, Government Highline Canal <br />diversions for'the first 10 days of November were returned to the river. This is probably <br />the reason why a decrease in the local diversion was not observed when the Government <br />HighIine was shut down on the 11th. <br /> <br />Local Irrigation Company Impacts <br />on Gaged Flows in the Critical Reach <br /> <br />,... <br /> <br />~ <br />~2S00 <br />" <br />~ <br /> <br />----_..-----------~---------------------------_._----------_.--------------------- <br /> <br />.~ <br />Cl <br />.E.... <br />O! <br />" <br />j '" <br />-c:l <br />a <br /> <br />loe&lln1loW Is ~ 8Sthe clifference <br />__._________________________._____~e~~~~m~~~-.--------------.------------ <br /> <br />'" <br />s:"'" <br />o <br />lI:; <br />-c:l <br />" <br />~"" <br />o <br /> <br /> <br />~- - ~'~ <br />--.....:-::- <br /> <br />) 4 6 j ~ ~ ~ n ~ ~ u n ~.n ~ ~ n 21 23 ~ a. z " n ~ ~ ~ <br />November 1994 <br /> <br />1---- 27.5Mi1eRdGage II LocalIrr.Div, - Palise.deGage <br /> <br />Figure 9 <br />
