Jennifer Lindahl, P.E. Page 4 of 8 Bromley Lakes SWSP April 3, 2017 information at this time regarding the use of the five shares from 1986 to 2005. After 2005 RMCC started using the five shares in SWSPs. A copy of the Report in case no. 2009CW279, dated June 2010 prepared by Applegate Group (“Applegate”) was submitted to this office with the 2010 SWSP request. The June 2010 Report describes the lands historically irrigated by the 5 Fulton Ditch shares as follows: 4.8 acres of 29 acres at the Arends Farm (Section 14, T1S, R67W), which were irrigated by 5 of 30 shares now owned by RMCC. The dry up area is within the Cell 3/Lot 1 area, which has an approved liner. The average monthly farm headgate deliveries, total return flows and stream depletions extracted from 2010 Report of the 30 shares are summarized in Table 3. As shown in Table 3 (columns 1 through 3) the Arends Farm headgate deliveries average 84.76 acre-feet, total return flow averaged 31.93 acre-feet and net stream depletions averaged 52.82 acre-feet per year. Therefore, for the purpose of this SWSP in order to determine the HCU credits attributable to RMCC’s five shares for the period of 1950 through 1985 you used the depletion pattern and return flow factors from the decree in ca se no. 2009CW279 and adjusted these values by 5/30th or 1/6th of the values for the entire farm (columns 4 through 6 of Table 3).The decree in case no. 2009CW279 relied on the Applegate Report regarding the HCU assumptions for the change of use of the 105 Fulton Ditch shares. Although the Report determined the annual o n farm depletions for the 105 Fulton Ditch shares as 194.8 acre-feet, according to paragraph 8.4.4 of the decree in case no. 2009CW279 the historical net depletions of the shares averaged 1.83 acre-feet per share (191.9 acre-feet). Therefore, the values in Table 3, columns 4 through 6 were multiplied by 98.5 percent (191.9/194.8) to account for the reduction in the historical net depletions of the shares in case no. 2009CW279. In addition these values were again multiplied by 69.7 percent (46/66 years) to account for the 20 years out of 66 years (1950 through 2015) of unknown use of the 5 shares from 1986 through 2005. This resulted in an annual on-farm depletion of 1.20 acre-feet/share, as shown on the attached Table 3. Based upon the decreed return flow factors, the historical farm headgate delivery of the shares averaged 1.94 acre-feet/share and the return flows averaged 0.73 acre-feet/share. The total farm headgate, return flows and net stream depletions associated with the RMCC’s five share used on the Arends Farm are presented on the attached Table 3. Based upon the above HCU analyses, RMCC’s 5 Fulton Ditch shares will yield 6.04 acre-feet in 2017 as summarized below: RMCC’s 5 Fulton Ditch shares depletions (acre-feet) *The April through October factors are applied to the daily farm headgate deliveries and the November through March factors are applied to the prior year annual farm headgate deliveries For the purpose of this SWSP the SEO has accepted the revised HCU analysis based on previous change case no. 2009CW279 and based on the adjustment provided. The City of Brighton will measure and deliver the 5 shares of Fulton Ditch water directly to the river (via Brighton’s Fulton Ditch augmentation stations) or to storage at Kenneth Mitchell Lake, Erger Pond, or 124th Storage Pond. RMCC will measure and report any deliveries of its shares to the river or storage via the Erger Fulton Lateral. RMCC will measure the delivery of any shares to storage and also measure any release from storage to the South Platte River. The City of Brighton will measure and report delivery of all augmentation supplies leased to RMCC.
