| Relation | Central Utah Project; Western Waters Digital Library; consultation AND coordination continued response see the response to comment no 111 134. 134 comment operational impacts are not adequately addressed there is only a cur sory review of the true environmental effects of the diamond fork power system operation it is misleading to talk about the initial opera tion effects when the project is purportedly justified on its maximum operation capability the passing reference to daily drawdowns draw downs mini mizes the dramatic aesthetic ecologic and safety impacts of the draw downs that can be expected at monks hollow reservoir and fifth water res ervoir there is no identification of studies done which justify a mini mization mication miza tion of this drawdown there are no illustrations of the impacts of the drawdown there is no mention of user acceptance of this drawdown without user acceptance recreational benefits may be overstated there is no description of the effect of this drawdown on the ecology of the area and finally there is no discussion of the operational problems of this drawdown during the winter season when ice forms on the surface of the reservoirs response syar and sixth water reservoirs would be relatively small reservoirs which would not store water for consumptive use downstream maximum drawdowns draw downs would occur on a daily basis under the recommended sixth water flow through alternative described in this FES syar reservoir would fluctuate about 26 feet daily and sixth water reservoir would fluctuate about 4 feet daily monks hollow reservoir would provide storage through the winter months and regulate releases to downstream users throughout the entire year fluctuations in monks hollow reservoir would be about 50 feet on a seasonal basis the seasonal drawdown would occur during the summer irrigation season of may through september no recreational use is planned for syar or sixth water reservoirs the reservoir fluctuations described on page 46 of the DES were intended to show the effects from minimum and maximum operating conditions for the fifth water pumped storage alternative the annual net benefits given in table 19 for that alternative are based on a plant factor of 17 per cent which represents an average operating condition the maximum operating condition is equivalent to a plant factor of approximately 30 percent daily fluctuations under the fifth water pumped storage alternative would range from 8 to 16 feet for fifth water reservoir daily fluctua tions eions in monks hollow reservoir would range from 14 to 25 feet the effects of reservoir operation on the ecology of the area are included in chapter IV of the FES see also comment no 107 during public information and scoping meetings a strong desire was expressed by the public to include recreation facilities for fifth water and monks hollow reservoirs this desire was expressed even after the 297 |
