6.0 AUGMENTATION REPLACEMENT SOURCES <br />The 2009 Lower Latham SWSP provides augmentation water from the following sources: 1) <br />consumptive use credits from 24.5 shares in the LLDC; 2) consumptive use credits from 13.5 shares <br />in the Union Ditch Company; 3) consumptive use credits from 15.19 shares in the Greeley Irrigation <br />Company; and 4) fully consumable water available from the City of Longmont (Longmont) pursuant <br />to an exchange agreement. A description of each of these sources and the replacement credit is <br />provided within the 2009 SWSP, which is included in Appendix C. The water rights which are <br />subject to this loan application are expected to be included within the LLRC SWSP or plan for <br />augmentation beginning in 2011. <br />The exchange of water agreement with Longmont allows LLRC to exchange Colorado-Big <br />Thompson (C-BT) water to Longmont in exchange for fully consumable water. The 2009 ageement <br />recently expired. LLRC is currently pursuing an annual renewal to the Longmont exchange <br />agreement and is concurrently pursuing a long-term agreement. Unless a long-term agreement can <br />be obtained, this augmentation replacement supply will not be available in a permanent plan for <br />augmentation and therefore, the alternate replacement sources LLRC is seeking funding from CWCB <br />for will be needed. <br />7.0 POTENTIAL ALTERNATIVES <br />7.1 Water Ri�hts <br />LLRC has considered several potential alternatives to achieve the stated goals including multiple <br />replacement water sources for use within the plan for augmentation and the potential for no <br />additional sources. Based on our analysis, it has been concluded that additional replacement sources <br />are necessary in order to provide sufficient replacement water during extended drought periods. <br />LLDC shares have been determined to be an excellent replacement source because they have senior <br />water rights that sustain a high yield during both average and drought years. In addition, <br />implementation of the shares into the LLRC plan for augmentation is easily achieved from an <br />operational standpoint. The location of the point of the diversion and river delivery structures <br />provides augmentation deliveries in the location necessary for the plan for augmentation. Also, the <br />close working relationship between the LLRC and LLDC provides assurance that the necessary <br />-5- <br />
