Replacement Sources Projected 2011 Yields (acre -feet) Comments Smith & Emmons Ditch 0.0 1.5 shares total; not to be used in 2013 Leggett Reservoir 0.0 16.5 shares total; not to be used in 2013 Godding, Dailey & Plumb Ditch 0.0 3 shares total; not to be used in 2013 Left Hand Ditch Company 0.0 4 shares total; not to be used in 2013 City of Longmont Lease 0.0 Annual lease if necessary Jared Dains South Platte Combined Replacement Plan January 9, 2013 Page 9 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 2013. Should a lease from PRPA be required a copy of the lease must be provided to the SEO, division engineer and water commissioner prior to the use of the water. St. Vrain River 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. The applicant may only utilize the 19.6 shares 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.
