<br /><::: <br /> <br />only the latter method since then. This method. however. gives data from <br />which canal' losses cannot be computed. For computations from January 1. 1988. <br />to the pres~nt. flows for the wasteway"furnished by Imperial Irrigation <br />District CIID) have been used for both monthly and yearly accounting instead <br />of the USGS data. Assessments of canal losses using these data appear to give <br />a better accounting of water use than making no calculation of canal losses. <br /> <br />..'...... <br />'......,/ <br /> <br />c.:) <br />C:;:J <br />-.1 <br />~\ <br /> <br />The IID data are available on the monthly FAX report through YFO or fro. Janie <br />Jo Smith at Hoover Dam. These data originate on IID's "logsheet" at Imperial <br />Oam and should be obtainable electronically through YFO when IID makes the <br />short-tiMe-increment data available' to Reclamation with the software and <br />hardware with which Reclamation has supplied them. Monthly and yearly <br />accounting both use the same data in this case. The Yuma USGS office has been <br />informed of the inadequacy of the measurements at the Yuma Main Canal Wasteway <br />but has offered no plan for action. Further contact is needed with the USGS <br />to work out remedial action. <br /> <br />Line 3 - Water wasted (water not used for a diversion nor a scheduled return <br />to the river) could be noted here. The entry on this line would allow. in <br />conjunction with Lines 2 and 4. a separation to be made among scheduled spills <br />(returns to ~iver). diversions for beneficial use. and wa~er was~ed. Were <br />water to be wasted. a line would have to be added to the WLDS showing which <br />diver~er wasted ~he water and where it was wasted, so that the was~e flow and <br />the seepage loss could be charged to the diverter. This is exemplified by the <br />entries for ~he Yuma ~ain Canal Wasteway, the "divert ern being, in this case, <br />Reclama"tion. <br /> <br />A =eview of ~he record during the las"t 10 years shows this line not to have <br />been used. It has been brought along in the present format to maintain format <br />consi$tency until a definitive decree accounting methodology has been se~led <br />upon. No data are presently being received for entry here. <br /> <br />Line 4 - All diversions for beneficial use from the canal. <br />same as that on Line 31 in the A.F. Oiverted column (total <br />minus the flow through the Yuma Main Canal Wasteway. <br /> <br />This value is the <br />acre-feet diverted) <br /> <br />Line S - Total System Loss is the seepage from the canal. and is obtained by <br />subtracting the sum of Lines 2. 3. and 4 from the value in the last coluan to <br />the right in Line 1. The first five lines of the WLDS serve only to subtract <br />all quantifiable amounts leaving the canal from the total amount entering at <br />Siphon Drop., <br /> <br />5 <br />
