i Mr. Jared Dains, P.E. Page 4 of 9 May 7, 2015 As specified in case no. 1996CW658, all deliveries of GIC water incur a return flow obligation to the stream system made up of a surface and subsurface component. The surface component of the return flow obligation of GIC direct flow water will be calculated by multiplying deliveries by 0.237 (23.7%). The surface component of the return flow obligation associated with the Applicant's use of Fossil Creek Reservoir water will be calculated by multiplying those deliveries by 0.201 (20.1%). The subsurface component of the return flow obligation will be calculated by multiplying the average annual delivery of GIC water, shown above, by the monthly subsurface return flow factors given in Appendix A-2 of the decree entered in case no. 1996CW658 (see Table 4). As shown in Table 4, the estimated subsurface return flow obligations for GIC direct flow deliveries and Fossil Creek reservoir deliveries total 6.88 acre-feet and 0.01 acre-feet, respectively, for this plan period. The quantity of GIC water remaining after the Applicant has satisfied its return flow obligations is equivalent to the historical consumptive use attributable to the shares. For the purposes of this SWSP, you have used a projected yield of 20.31 acre-feet of GIC direct flow water per share and 1.19 acre-feet of Fossil Creek Reservoir deliveries per share. These amounts are consistent with projected deliveries per share for Year One as described in paragraph 28 of the decree entered in case no. 2003CW348. Projected deliveries for Year One were calculated in accordance with paragraph 20.3.3 of the decree entered in case no. 2003CW99, and are based on 2002-2006 recorded deliveries. The use of the Year One projected deliveries is acceptable for this plan period and appears reasonable based on current conditions. As shown in the attached Table 5, total credit for the Applicant's 3.0 GIC shares is projected to be 49.34 acre-feet for the irrigation season (not including subsurface return flow obligations, which are incorporated as part of the augmentation requirement in Table 5). Should actual GIC deliveries be less than projected deliveries, the Applicant is obligated to obtain additional or alternate replacement supplies to replace all depletions at the Greeley Pit. Based on the actual annual deliveries reported for 2011- 2014, the 10-year farm headgate delivery will not exceed 186.43 acre-feet per share, or 559.29 acre- feet for all 3.0 shares, so long as deliveries do not exceed the annual limitation of 25.26 acre-feet per share, or 75.78 acre-feet for all 3.0 shares, decreed in case no. 1996CW658. The Applicant's GIC shares will be delivered to the Cache la Poudre River at the23rd Avenue and Fourth Street Return Station (WDID 0302318). Those replacements will be made directly adjacent to the Greeley Pit. Due to the close proximity of the return station to the Greeley Pit, no transit losses will be assessed for the delivery of the GIC shares. The replacement deliveries will be made above the Ogilvy Ditch, which is typically the first calling water right below the Greeley Pit point of depletion during the period of April to October. Bucklen Equipment Company Lease The Applicant has entered into an agreement with Bucklen Equipment Co., Inc. for the lease of excess augmentation credits from the Bucklen Pit SWSP (WDID 0302538) during the months of April through October 2015. A copy of the lease is attached. The excess augmentation credits will be generated from six (6) GIC shares owned by the Bucklen Equipment Co., Inc. After use in Bucklen Pit SWSP, the shares are projected to produce a total of 60.7 acre-feet of excess credits during the 2015 irrigation season. Hiner anticipates using a total of 23.0 acre-feet of excess credits in this SWSP, as shown in the table below.

The Bucklen GIC shares will be delivered to the Cache La Poudre River at the 23rd Avenue and Fourth Street Return Station.
