Colorado Springs Utilities Pilot Project Proposal November 16, 2018 Page 7 the practice of rotationally fallowing substantial agricultural lands (currently estimated at up to 700 acres annually to supply 1,000 acre-feet of water and 3,500 acres annually to supply 5,000 acre-feet of water) that have been historically irrigated to allow for the leasing of the historical consumptive use water for temporary municipal use by CS-U. See Super Ditch Resolution. The CS-U Pilot Project will demonstrate cooperation among three different canal companies, a different typ e of water demand (CS-U drought recovery), participating farmers, and the Super Ditch. See Super Ditch Resolution; Catlin Resolution; Fort Lyon Letter of Intent; High Line Letter of Intent . The cooperation amongst these groups will be facilitated through Super Ditch’s management of operations. Id. The State, the participants, and other interested parties will have the opportunity to evaluate the feasibility of delivering leased water to temporary municipal users on a large scale using lease water fro m multiple ditch companies and their shareholders with more flexibility to fallow irrigated land through operation of the CS-U Pilot Project. Id. The CS-U Pilot Project will provide data from which the CWCB and State Engineer can further evaluate the efficacy of using a streamlined approach for determining historical consumptive use, return flows, the potential for material injury to other water rights, and conditions to prevent injury on a large scale. Unlike the Catlin Pilot Project, the CS-U Pilot P roject will involve lease water from shareholders in three different canal companies and provide maximum flexibility to irrigators to determine which acres will be fallowed. Applicant’s consultants will conduct an historical use analysis using the Leasing Fallowing Tool that has been developed for the CWCB. It will also utilize the assumptions, presumptive factors and methodologies set forth in Section II.G of the Criteria and Guidelines (or successor), which were conservatively developed to streamline and standardize the historical use analysis so as to prevent injury to vested water rights, conditional water rights, or contract rights to water. Id. Through this, along with the imposition of protective terms and conditions, the CS- U Pilot Project will d emonstrate how to operate, administer and account for the practice of fallowing irrigated agricultural land under multiple ditch companies for leasing water for temporary municipal use without causing material injury to other vested water rights, decreed conditional water rights, or contract rights to water. Id. The CS-U Pilot Project would not involve the fallowing of the same land for more than three years in a ten-year period because the contract between Super Ditch and CS-U only allows CS -U to lease water in three out of ten years. The CS-U Pilot Project will involve the fallowing of lands irrigated under three different ditches and demonstrate cooperation and operation among Super Ditch, the canal companies, and individual shareholders. The CS-U Pilo t Project would not involve any transfer or facilitation of transfer of water across the continental divide by direct diversion, exchange, or otherwise, nor does it involve the transfer or facilitation of transfer of w ater out of the Rio Grande Basin by direct diversion, exchange or otherwise. See Map (Exhibit G). The source of water is water native to the Arkansas River; all historical irrigation with this water has occurred in the Lower Arkansas River Valley in Pueblo, Otero, Prowers, and Bent Cou nties under the Catlin, Fort Lyon, and High Line canals; and the proposed temporary municipal use will occur within CS-U’s water service areas located wholly within El Paso County. Section II.C of the Criteria and Guidelines allows the CWCB to approve a pilot project involving more
