Greeley Pit SWSP April 6, 2020 Plan ID 2965 Page 5 of 10 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 6.25 GIC shares is projected to be 102.80 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 2011-2015, the 10-year farm headgate delivery will not exceed 186.43 acre-feet per share, or 1165.19 acre-feet for all 6.25 shares, so long as deliveries do not exceed the annual limitation of 25.26 acre-feet per share, or 157.87 acre-feet for all 6.25 shares, decreed in case no. 1996CW658. Any SWSP renewal request should propose adequate terms and conditions to assure that an expansion of use of the Applicant's shares will not result if the Applicant reaches their annual volumetric limit and ceases diverting water or decides not to take delivery of their shares. The Applicant's GIC shares will be delivered to the Cache la Poudre River at the 23rd 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. City of Aurora Lease The Applicant has entered into an agreement with the City of Aurora ("Aurora") for 28.9 acre-feet of fully reusable municipal wastewater return flows that will be used to make replacements during the period of November 1, 2020 through March 31, 2021. The lease may be extended for additional one-year periods. It is anticipated that a lease extension will be obtained for 31.6 acre-feet of water for the period of November 1, 2021 through March 31, 2022. This SWSP will only be extended for the period of April 1, 2021 through March 31, 2022 if a copy of the executed lease is provided to this office on or before March 31, 2021. The releases will be made from the Metro Waste Water Reclamation Facility (WDID 0200700) located in Denver on the South Platte River approximately 66 miles upstream from the Cache la Poudre confluence. Therefore a 16.5% (0.25% per mile) river transit loss will be assessed on all deliveries, unless otherwise determined by the Water Commissioner for District 2. During the months of November through March, it is possible for a call to be placed at the Evans Number 2 Ditch headgate for Milton Reservoir, or a call at the Western Ditch, or the Union Ditch to fill Lower Latham Reservoir, any of which could potentially sweep the river. It is the Applicant's responsibility to track the daily call and make arrangements as necessary to ensure this water is bypassed or otherwise delivered to the Cache la Poudre and South Platte River confluence. The District 3 Water Commissioner has confirmed there is no call in the winter for the stretch of the Cache la Poudre River between the
