PRPA has an Agreement dated August 10, 1978 for Reuse of Water for Energy Generation with the City of Fort Collins ( "Fort Collins ") and Water Supply and Storage Company ( "WSSC "). PRPA, Fort Collins, and WSSC also obtain approval of a plan for augmentation including reuse of water in case no. W- 9322 -78. This water right was decreed in case no. W- 9322 -78 as developed water, not tributary to the South Platte River. The Court found that 4,200 acre -feet, or more per year will be available from Fort Collins to the PRPA to be used primarily for cooling purposes in connection with its Rawhide Energy Station. Pursuant to the decree in case no. W- 9322-78 if PRPA does not require the water for its own purposes, it or Fort Collins or other water users designated by it may utilize the water for any other beneficial purposes including augmentation. In addition, PRPA has entered into an Agreement with the North Poudre Irrigation Company ( "North Poudre") dated November 15, 1979 which grants PRPA the right to store surplus water (which is surplus water beyond the needs of the Rawhide Energy Station) in the Fossil Creek Reservoir and lease such water to others who can use such water from Fossil Creek Reservoir through direct delivery. At this time, the Applicant is expecting that a PRPA lease will not be required for 2012. However, should the Boyd & Freeman augmentation station not be installed as assumed, then Aggregate may seek a lease from the PRPA. Information regarding additional leases must be provided to the SEO prior to the use of the water. 2012 projected yield may vary from previous estimated of the net yield due to the computed return flow obligations based on the previous year's actual water deliveries. Smith & Emmons Ditch Aggregate owns 1.5 of 8 total outstanding shares in the Smith & Emmons Ditch Company. The 1.5 Smith & Emmons Ditch shares were historically used to irrigate 68 acres of pasture grass. Using a Blaney - Criddle analysis the potential crop consumptive use for the 68 acres was determined to be 108.7 acre -feet. Assuming a 10% ditch loss and 55% farm efficiency the dry year consumptive use was determined to be 91.65 acre -feet. The applicant may only utilize the 1.5 shares of Smith & Emmons Ditch at such time as all required measurement and bypass structures have been installed and approved by the water commissioner. Applicant does not expect this to occur during the duration of this SWSP. Leggett -Owens Reservoir Donald J. Sherwood owns 19.6 shares of the Leggett -Owens Ditch and Reservoir Company, which Aggregate may use for augmentation pursuant to the mining lease agreement. During an average year the 19.6 shares represents 60 acre -feet of water and can be released when needed. The consumptive use credit available from the 19.6 shares is estimated at 33 acre -feet, based on a 55% efficiency.
