<br /> <br />canal minus all measured amounts of water leaving canal gives total system <br />loss. <br /> <br />(::::> <br /> <br />'.,,1 <br /> <br />c:.:> Lines 7 throu'fh 16 - As on the Yuma Main WLDS, this WLDS can be completed by <br />C~ making entries only in the AF Diverted column. given an already-set-up Lotus <br />~ 1-2-3 spreadsheet. For monthly reporting. the data required for entry appear <br />on the USGS monthly provisionals or the YFO FAX report. The AF diverted <br />column shows two positions for Reservation and Valley Division delivery <br />points. The top position for each delivery point is the Indian Unit component <br />of the delivery; the lower position is the Deeded (Bard) component. For <br />monthly computations, entries for each componen~ for the Reservation Main, <br />Titsink, Yaqui. Pontiac. and Walapai Canals are computed by multiplying the <br />total delivery for each named canal, by the ratio of the number of acres <br />served by the canal in the unit under consideration (Indian or Deeded) to the <br />combined adreage of the units irrigated by this same canal. These ratios for <br />the Indian Unit and the Bard Unit. respectively. are 0.2645 and 0.7355 for the <br />ReservatiOn Main Canal; 0.6336 and 0.3664 for the Titsink Canal; 0.0851 and <br />0.9149 for the Yaqui Canal; 1.0 and 0 for the Pontiac and the Walapai Canals. <br /> <br />As an example. the Indian Unit served by the Reservation Main Canal (RMC) is <br />about 2074 acres and the Deeded Unit acreage served by this canal is about <br />5767 acres. Combined. they total about 7841 acres. To get the acre-feet <br />diverted by the Indian Unit for the RMC. the total in acre-feet diverted for <br />both units for the canal is multiplied by 0.2645 (2074 divided by 7841). For <br />the Deeded Unit, ~he total acr~-feet diverted for both units for the canal is <br />multiplied by 0.7355 (5767 divided by 7841). <br /> <br />For the yearly report YFO furnishes an annual summary in their hydrographic <br />tabulations which give the actual deliveries to the Indian and Bard Units. <br />For the Reservation Main Canal. a value for the spill at the Cocopah Wasteway <br />is included on the annual summary. a value not reported by the USGS nor given <br />on the monthly FAX from YFO. This spilled water is assigned to the Indian and <br />Bard Units in proportion to the delivery each takes from the AAC at the head <br />of the RMC. This assignment is made from Form No. YPO-116a as follows: <br /> <br />For the Indian Unit - (((6+8)/(6+7+8+9))1l2)+(6+8) <br /> <br />For the Bard Unit (((7+9)/(6+7+8+9))ll2)+(7+9) <br /> <br />The numbers ,in the preceding formulas indicate the appropriate monthly value <br />in the columns with these numbers on Form No. YPO-116a. <br /> <br />10 <br />
