Post-Pilot Project Return Flow Obligations Using the above-described URFs for the Participating Farms, post-fallowing lagged return flow obligations for operations are estimated to total 805.2 acre-feet over the following 5 years, with nearly half of the lagged return flow obligations occurring in the first year (see Appendix I, Table I- 1). Assuming 3 years of pilot project operations under average year conditions, total Post-Pilot Project Return Flow Obligations are estimated at approximately 1,193.3 acre-feet for less than 5 years following the last month of operations (see Appendix 1, Table 1-2). Post-Pilot Project Return Flow Obligations will be met via release of water from the sources available to Colorado Springs. E. Source of Water to Replace Historical Return Flow Obligations During the term of the Colorado Springs/Super Ditch Pilot Project, all return flow obligations (consisting of both tailwater and lagged deep percolation return flows)occurring during the irrigation season which result from diversions during the same irrigation season will be met using portions of the farm headgate deliveries of the water available from the fallowing of historically irrigated lands. All excess lagged stream depletion credits may be exchanged into Pueblo Reservoir, or step exchanged, either for all approved uses by Colorado Springs and/or for later use to replace the remaining pilot project lagged deep percolation return flow obligations. In addition,Colorado Springs has various sources of water that will be available to meet lagged deep percolation return flow obligations owed during and after the conclusion of the Pilot Project's operations. Colorado Springs proposes to use any fully consumable water available to Colorado Springs Utilities to replace such lagged deep percolation return flow obligations, including, but not limited to, those listed in Appendix H. To the extent possible, Colorado Springs intends to replace the lagged deep percolation return flows with other fully consumable sources available to it in Lake Meredith, at the confluence of Fountain Creek, or in Pueblo Reservoir, and to fully consume the deep percolation return flow credits exchanged to Pueblo Reservoir by exchanging this water into its municipal system under the decree entered in Case No. 05CW96. Pursuant to the Letter Agreement between the Super Ditch and Colorado Springs, the Super Ditch and Colorado Springs will maintain a projection that shows the monthly replacement obligations owed to the Arkansas River and accounting which demonstrates that the river is kept whole. As demonstrated below, Colorado Springs has more- than-sufficient water available to it from transmountain sources and changed irrigation water rights (i.e., the Colorado Canal) to meet these obligations. As shown in Appendix H, Colorado Springs owns shares in a number of ditch and reservoir companies with water rights on or tributary to the Arkansas River. Where necessary, these ditch and reservoir company shares have undergone water court proceedings to changes the use of those water rights,whereby the historical consumptive use associated with those shares has been quantified. These sources are listed in Table 9 below: Martin and Wood Water Consultants,Inc.
