8.3.4 Taylor Park Project A yield analysis of the Taylor Park Project was carried out using various assumptions regarding water rights, instream flow requirements in the Taylor River below Taylor Park Dam, and minimum allowabie water tevels for Taylor Park Reservoir. Regarding the water right assumption, an export from TayTor Park Reservoir could possibly be supported by existing rights such as the Uncompahgre Valley Water Users Associat9on's (UYWUA) 7aylor Park storage decree with replacement water purchased from Blue Mesa Reservoir; by transfer of the Upper Gunnison River Water Conservancy District's (UGWCD) conditional storage decrees; by transfer of some other existing conditional storage decrees; or by a new storage decree. Implementation of any purchase agreement for water from Blue Mesa Reservoir would be subject to the terms of the assignment of the Blue Mesa Reservoir storage and direct-flow water rights from the Colorado River Water Conservation District (CRWCD) to the United States. Use of Blue Mesa water in export projects is conditioned upon prior consent of the parties to that agreement. There may also be other legal or institutional constraints regarding purchase of Blue Mesa water; this study has not analyzed such constraints. Important considerations in assessing the yield of a new water right include the effect of privately held instream flow decrees on the Taylor River below Taylor Park Dam, and the potential for full administration of the Aspinall Unit power rights by the State Engineer's office. Tfie privately held decrees for up to 445 cfs year-around have the potential to severely limit the yield of junior upstream appropriations or changes of use by senior upstream rights, regardless of whether replacement storage is constructed elsewhere in the basin. Scenario 13 assessed the storable flow yield of a new right for transbasin diversion assumi�g this privately held instream decree is maintained and exercised. [b
