D. Measure 4: Delivery of water to the 15-Mile Reach in the Grand Valley <br /> pursuant to the Upper Colorado River Recovery Program. Refer to <br /> section IV.b.iv of the Implementation Outline. <br /> 1. This is an existing mechanism by which water is delivered from <br /> upstream reservoirs for the benefit of the endangered fish species <br /> in the Grand Valley on a temporary basis. The water deliveries are <br /> protected through the subject stream segments downstream <br /> through the 15-Mile Reach of the Colorado River. The SG <br /> recognizes that negotiations are currently proceeding in a separate <br /> forum to develop alternative sources of supply for the water users <br /> portion (10,825 acre feet) of water delivered to the endangered fish. <br /> The water users' portion averages approximately_% of the total <br /> amount of water delivered to the fish, and _% of the water <br /> delivered to the fish from sources above Kremmling. The SG <br /> recognizes that within the next ten[??] years, approximately_% of <br /> the water users' obligation likely will cease to be delivered from <br /> points above Kremmling, and instead will be made from sources of <br /> water downstream of the subject BLM stream reaches. Significant <br /> releases of water to the endangered fish can be expected to <br /> continue to be made from Green Mountain Reservoir pursuant to <br /> the Recovery Program and the operation of the Green Mountain <br /> Reservoir Rule Curve established in the Orchard Mesa Check <br /> Decree, Case No. 91CW247, Water Division 5. No milestones are <br /> necessary to implement this existing long-term protection measure. <br /> II. Mechanisms for Addressing Changed Circumstances in Long-Term Protection <br /> Measures <br /> A. Examples of Changed Circumstances that Trigger Action of the SG. <br /> 1. Measure 1: Examples of a material change in circumstances <br /> include, but are not limited to, the CWCB's appropriation of an 1SF <br /> that is not consistent with the SG's recommendation to the CWCB, <br /> a significant new water right appropriation upstream of or within the <br /> subject stream reaches that is senior to the CWCB's anticipated <br /> ISF(s), the CWCB's determination to abandon its instream flow <br /> water right or to allow the inundation of part of the instream flow <br /> right; an administrative or judicial reduction of the instream flow <br /> right; or the implementation of an increase in the amount of the <br /> instream flow right, either by appropriation or by donation. <br /> Page 3 of 4 <br />
