| Relation | Central Utah Project; Western Waters Digital Library; would have been located in the lake fork river drainage basin they included 1 pigeon water dam and reservoir together with an enclosed pipeline conveyance system 2 clay basin dam and reservoir and 3 rehabilitation of the farnsworth canal the fourth project mcguire draw dam and reservoir would have been located in the uinta river drainage basin these four authorized projects were evaluated for their engineering biological and economic feasibility the feasibility evaluation indicated that the pigeon water site was not economically viable because of the small volume of storage available the high cost of the structure and the unreasonably high cost per acre foot of water because of these limitations alternatives to pigeon water dam and reservoir were considered and evaluated the enlargement of the existing big sand wash reservoir was determined to be the most economically feasible and environmentally acceptable alternative that would provide the same benefits purposes and needs as the pigeon water site cham ch2m HILL horrocks 1994 the feasibility evaluation indicated that the clay basin site was not feasible because of deep active landslides this significant geologic hazard was identified by the USBR during earlier studies in 1974 and was confirmed in 1991 during feasibility investigations cham ch2m HILL 1994 enlargement of the existing big sand wash reservoir was also identified as the best alternative that would fulfill the same purposes and needs as the clay basin site cham ch2m hillhorrocks HILL Horrocks 1995 the feasibility evaluation indicated that me the rehabilitation of farnsworth canal was not feasible because of an unacceptable loss of wetlands that would have occurred CUWCD 1996b several pipelines and other project facilities are included in the action alternatives as more feasible features to replace the rehabilitation of the farnsworth canal these facilities would contribute more broadly to the authorized objectives of increased efficiency enhanced beneficial uses and greater greaterwater water conservation examples of these alternative project features include stabilizing high mountain lakes establishing reestablishing re natural flow regimes in drainages downstream of stabilized high mountain lakes providing in stream flows for fish between moon lake reservoir and the new big sand wash feeder diversion structure providing fish passage at the new big sand wash feeder diversion structure and developing storing and efficiently conveying irrigation and mai mal water for basin use through new pipelines and expanded water storage capacity the feasibility evaluation also indicated that the construction of mcguire draw dam and reservoir was not feasible CUWCD 1997 the dam and reservoir site for this project was found to be unacceptable because of unsuitable geologic conditions the enlargement of the existing big sand wash reservoir and construction of a new pipeline to convey mai m&i water to roosevelt city and irrigation water to the state road area fulfills the same purposes and needs as mcguire draw dam and would benefit numerous residents within the uinta river watershed although the four projects specifically included in the authorizing legislation were determined to not be feasible for various reasons there are several feasible alternatives that can be built in the same area that do meet the congressional mandate to increase water efficiencies to enhance beneficial use of water and to achieve greater water conservation these alternatives are described in detail in chapter 2 of this final EA the proposed expansion of big sand wash reservoir by 12000 ac ft would provide the opportunity to meet these project purposes and needs using the enlarged off stream storage space 121 1 21 |
