those recharged amounts reach the stream. Conceptual schematic drawings for the Camp Ranch Recharge Facility are shown in Figures 3 and 4. The Mapes Well No. 1 may possibly be utilized as a retiming augmentation well. The well can be equipped so that it can pump through a pipeline that will discharge to the Huerfano River at times when the recharge facility is not able to provide the necessary accretions to the Huerfano River. Those well depletions as lagged to the stream will then later be replaced by use of the consumptive use credits from the Camp Ranch Water Rights. This process uses the Mapes Well as an augmented structure to retime and allocate the stream accretions from the recharge facility to correspond with the timing of the augmentation plan depletions to the river. Conceptual schematic drawings for the Mapes Augmentation Well are shown in Figures 3 and 4. As previously described, the proposed project includes construction of an off channel lined reservoir of approximately 25 acre -feet near Red Wing for storage of transferable consumptive use credits and delayed return flow obligations from the historically irrigated Camp Ranch property. An appropriative right of exchange will be applied for to allow the historical consumptive use entitlement and delayed return flows at the William Craig Ditch and the Jose Maria Ditch to be diverted by exchange at the Wilson Ditch headgate for storage in the proposed Red Wing Augmentation Pond for later release to replace the augmentation plan depletions and delayed/non - irrigation season return flows. A map of the exchange reach is shown in Figure 5. A preliminary analysis of exchange potential between Camp Ranch and the Wilson Ditch headgate was conducted. This analysis was performed for the eight years for which there are gage records at both the Manzanares Crossing Near Redwing gage (USGS Gauge No. 7111000) and the Badito gage (USGS Gauge No. 7112500). These eight years include two drought years, two flood years and four average flow years. The analysis of exchange potential shows that there is not a dry -up point in the river restricting exchange potential between the Wilson Ditch headgate and William Craig Ditch headgate. In fact, during the irrigation season, the exchange potential in this reach averaged approximately 43 percent of the flow of the river at the Manzanares Crossing Near Red Wing gage. As a result, we believe the Red Wing Augmentation Pond will be able to be filled by exchange with the historical consumptive use credits and delayed flows from the senior Camp Ranch Water Rights. 2.3.2 Water Supply Demands The HCWCD has utilized a Substitute Water Supply Plan and a Regional Rule 14 Replacement Plan for the last five years 2009 -2013 to provide augmentation water to 5 separate entities who were in danger of having their water use curtailed due to out of priority usage. A copy of the most recent approved SWSP and Rule 14 Plan are included in Appendix I. The current entities have demands of approximately 10 acre -feet of 100% consumptively used water are as follows: Huerfano County Road & Bride Malachite Spring CO 61 Water Association Gardner Water & Sanitation Dist. Paradise Acres HOA 1.0 3.0 2.0 3.0 1.0 Please note that the CO 61, Gardner and Paradise Acres groups utilize water wells for their water supply. The amounts shown are the annual depletions from pumping these wells. They are not the entire amount pumped. These demands will continue for the foreseeable future with a likely
