64 active shares in the Box Elder Ditch that operate under three priorities, originally <br /> decreed in Civil Action 320 (Case No. CA320) in the District Court, Larimer County, <br /> State of Colorado, on April 11, 1882. All three water rights are fairly senior and allow <br /> diversions under priority Nos. 15, 23, and 30. <br /> Table 11 -Box Elder Ditch <br /> Priority Adjudication Appropriation Decreed Flow Rate <br /> No. Date Date (cfs) <br /> 15 October 4, 1882 March 1, 1866 32.5 <br /> 23 October 4, 1882 May 25, 1867 8.33 <br /> 30 October 4, 1882 July 1, 1868 11.93 <br /> Historical Service Area <br /> Historically, the Box Elder Ditch serviced approximately 2,20011 acres below the Cache <br /> Ia Poudre River from its headgate. The Box Elder Ditch headgate is located slightly <br /> upstream of the Fossil Creek Reservoir Inlet Ditch headgate and services lands south of <br /> the Cache la Poudre River and upstream of the confluence of the Cache Ia Poudre <br /> River and Fossil Creek. The Box Elder Ditch crosses under the Cache Ia Poudre River <br /> and historically served the Three Bells property northwest of the Kyger Reservoir. <br /> Water Availability <br /> The Box Elder Ditch has historically diverted from April to October, according to records <br /> provided by the State. Prior change of use cases have decreed a diversion season of <br /> April 1 through October 31, which is consistent with historical operations. <br /> Delivery and Consumptive Use <br /> Pro-rata river headgate diversion between the years 1950 and 2012 averaged <br /> approximately 98.9 acre-feet per share. Appling a ditch loss of 15 percent, pro-rata <br /> farm headgate deliveries are 84.1 acre-feet per share. Assuming a farm efficiency of 50 <br /> percent, the consumptive use credit is estimated to be 42.0 acre-feet per share. <br /> However, compared to the average yield per share from decreed change of use cases, <br /> it appears this value is low. The average consumptive use from previous change cases <br /> is 47.8 acre-feet per share. For recently decreed change of use cases, the average <br /> consumptive use credit is closer to 45 acre-feet per share and this is the value used in <br /> this report. <br /> 11 Data from Decree in Case No. 94CW015, signed November 29, 1995, Applicant was the Swift Gravel <br /> Company. <br />
