Further investigation may show that the <br />USGS is smoothing the data to coincided with adjacent daily flows. This type of activity <br />may mask some of the affects of the up stream diversions which may be another cause of <br />the daily variability in the calculated local inflows. <br /> <br />III.3 27.5 Road Gage Daily Flow Variation <br /> <br />Figure 4 presents the maximum and minimum daily flow rates reported at the 27.5 Road <br />gage and the differences between the maximum and minimum daily flow rates. <br /> <br />Daily Flow Variation <br />at 27.5 Road Gage <br /> <br />,,,. <br /> <br />W~ <br /> <br />'" <br />~ <br />o <br />S::.oo .-- ---- <br />" <br />:2 <br />"" <br />a <br />l;j -, . - <br />::i! <br />"" <br />" <br />gp <br />0... <br /> <br /> <br />1 <br /> <br />--_.------ ._---,..,-,---- ."------j;f-..---.., ---_.",---_.,,------ _...- ..~ <br /> <br /> <br /> <br />..._- --... ~'j---- <br />~:I.,: <br />1 H ~ . <br /> <br />. ,__ ___.".__.____.. __J_ "___,, <br />, <br /> <br />u.. <br /> <br />~U~ <br /><l!l <br />" <br />~ <br /> <br />~ <br /><.:!l <br />~~oo ..:>... <br /> <br />.- <br />., <br />-J.... <br /> <br />c <br />o <br />3600.":: <br />" <br />.~ <br />"";> <br />~ <br />a.&OO .2 <br />~ <br />>. <br />""'ii <br />Q <br /> <br />- <br /> <br />... <br /> <br />o I^"'l't1ISqotllO<<ilff...91 ....,9ae..9.Dcl9a/'l"_9~9a ....,'iI~9~0C0'JIl..'ilall"'9 lJul9...."'...l5cv94O<o~J1_~P.~i41 0 <br /> <br />Monl11 <br /> <br />[- ~umD.ilyJ1o.... ---- umimumDWyFlo...

It's interesting to note that in November of each year there occur days <br />when the flow variation within a day approximates 1,000 cfs which we in part attribute <br />to operation of the Grand Valley Project (see Section Diversion Dam Operations versus <br />
