Kurtz SWSP April 15, 2013 exchange for releases from any or all of the reservoirs or any or all of the direct flow sources. The decreed information for these junior water rights is shown in the following table: ote: Total direct diversion from all sources not to exceed 11 cfs. Storage rates are 90 cfs for Rural Ditch and Page 3 Godding Ditch, 10 cfs for Godding Hollow and 100 cfs for Last Chance Ditch. Water was diverted through the Rural Ditch for storage in 112 Reservoir and the Dakolios Reservoir over the extended free river period that started in September 2009 and continued through the beginning of June 2010. According to the decree in case no. 2001 CW274, water stored in the reservoirs or used directly at the point of diversion may be used for replacement of depletions at the mining sites owned or leased by VCI. The Kurtz Pit site has been identified as one of the mining sites where the junior water rights decreed in case no. 2001 CW274 may be used as a source of replacement water. You indicated that as of November 1, 2012 the water stored in the reservoirs totaled 1,745 acre - feet consisting of a combination of Rural Ditch water and junior water decreed in case no. 2001 CW274. The attached Tables 3A and 3B show the reservoirs operations over the next two years. The average ground water contribution and direct and indirect precipitation for the two pits has been included in the study. The Applicant intends to exchange the junior water for some of the Rural Ditch water that had previously been stored in the 112 Reservoir. Thus, the replacements for depletions at Kurtz Pit will be satisfied by delivery of junior water decreed in case no. 2001CW274 and previously stored in the 112, Dakolios, and Von Ohlen Reservoirs. Delivery of augmentation water to the Saint Vrain Creek is subject to transit losses as determined by the water commissioner and the division engineer. Although not proposed to be used in this plan, additional replacements for depletions if necessary could be made by releases of a portion of four shares in the Rural Ditch Company water that is stored in the 112 and Dakolios Reservoirs. The Rural Ditch Company four shares were historically used to irrigate 158.9 acres on the 112- parcel site and these shares were used in the previous plans. Consumptive use credits from the 4 shares of the Rural Ditch that are not used to replace depletions during the irrigation season will be stored in the 112 Reservoir and subsequently released to replace non - irrigation season depletions. An application for a change of water right (to allow the applicant's Rural Ditch shares to be used in addition to irrigation for augmentation, replacement, exchange, commercial, industrial, recreational, piscatorial, wildlife propagation and storage) and approval of a plan for augmentation was filed with the Water Court in Case No. 2003CW306. The historical consumptive use of the four shares of the Rural Ditch water averages 265.50 acre -feet per year. Excess consumptive use credits from the four shares of Rural Ditch stored in the 112 Reservoir will also be
