Assuming a ditch loss of 15 percent and farm efficiency of 50 percent, approximately <br />4.25 acre-feet of consumptive use credit might be expected from these shares. These <br />values are used in this report. <br />Alternative No. 3 - Whitney Irrigating Ditch Company <br />Background <br />The Whitney Ditch Irrigating Company is a small mutual ditch company that operates <br />near the Town of Windsor under two priorities originally decreed in Case No. CA320. <br />Both priorities are fairly senior; the most senior right being Priority No. 7, which provides <br />the majority of the water in Whitney Ditch. There are atotal of 320 active shares in the <br />Whitney Ditch. <br />Table 9 - Whitney Ditch Information <br />PriorityAdjudicationAppropriationDecreed Flow Rate <br />No.DateDate(cfs) <br />7 April 11, 1882September 1, 186248.23 <br />48April 11, 1882September 10, 187112.95 <br />Historical Service Area <br />The Whitney Ditch diverts water from the north side of the Cache la Poudre River near <br />th <br />the NW corner of the SE ¼ of Section 19, T6N, R67W, in the 6P.M. in Water District <br />3. From its point of diversion, the Whitney Ditch has historically serviced around 4,000 <br />acres located along the north side of the Cache la Poudre River to the northwest edge <br />of Greeley. <br />Water Availability <br />The Whitney Ditch has historically diverted from April through September with reduced <br />diversions in October. In 1995, the Whitney Ditch diverted water as early as March. <br />Prior change of use cases have decreed the water available from April through October. <br />Delivery and Consumptive Use <br />Pro-rata river headgate diversion records between the years 1950 and 1998 averaged <br />33.4 acre-feet per share. Assuming a ditch loss of 15 percent, pro-rata farm headgate <br />deliveries were 28.4 acre-feet per share. Assuming a farm efficiency of 50 percent, the <br />consumptive use credit is estimated to be 14.0 acre-feet per share. These estimates <br />are consistent with the prior change cases and are the values used in this report. <br /> <br />
