Replacements Lower Poudre River Page 6 2012 Projected yields may vary from previous estimates of net yields due to the computed return flow obligations based on the previous year's actual water deliveries Whitney Ditch Five of the shares of Whitney Ditch were historically used to irrigate 65 acres at W. W. Farm consisting of 65% corn, 30% alfalfa and 5% beans. Using a Blaney - Criddle analysis the potential crop consumptive use for the 65 acres was determined to be 96.8 acre -feet. Assuming a 10% ditch Toss and 55% farm efficiency the dry year consumptive use was determined to be 64.3 acre -feet. Six of the shares of Whitney Ditch were historically used to irrigate 57.1 acres of pasture grass at Orr Farm #1. Using a Blaney - Criddle analysis the potential crop consumptive use for the 57.1 acres was determined to be 96.8 acre -feet. Assuming a 15% ditch Toss and 60% farm efficiency the dry year consumptive use was determined to be 84.64 acre -feet. 2.5 shares of the Whitney Ditch were historically used for the irrigation of 24 acres at Orr Farm #2. A total of 40 shares of the Whitney Ditch were recently changed in case no. 2002CW390 that was approved by the water court on September 26, 2007. As in case no. 2002CW390, this plan will estimate ditch loss to be 15 percent, a maximum farm irrigation efficiency of 60% will be used, and a return flow split of 50/50 between surface and subsurface return flows will be used. The total net consumptive use available for the dry-up of this 24 -acre property is 37.3 acre -feet. For 2012, the applicant will utilize all of the 13.5 Whitney Ditch shares.
