<br />Transmountain Diversion Project. A summary of potential environmental impacts <br />associated with development of these projects is as follows: <br /> <br />~ <br /> <br />..... <br />\,.,.) <br />c.., <br />Q".) <br /> <br />The Taylor Park Project would consist of exporting 42,000 af of water <br />from the existing Taylor Park Reservoir while maintaining a minimum <br />instream flow downstream of Taylor Park Dam ranging from 75 to 150 cfs <br />. , <br />and also maintaining a minimum pool in Taylor Park Reservoir of elevation <br />8,268 (23,400 af). The streamflow below the dam under this plan would be <br />reduced from what is experienced at present and what has been predicted <br />under the No Action scenario. This will have an adverse impact on <br />rafting on the Taylor River. Although the impact of the new flow regime <br />on the Taylor River fishery has not been studied in detail, it is <br />believed that the flow regime is adequate to maintain the present fishery <br />populat i on. The' Taylor Park Reservoi r actually experi ences 1 ess <br />fluctuation under this proposed operation which would be, beneficial to <br />recre,at i on use and perhaps the exi st i ng 1 ake fi shery. B1 ue Mesa <br />Reservoir, on the other hand, operates at slightly lower levels which may <br />possibly adversely affect recreation and the fishery at that location. <br /> <br />It should be noted that variations of the Taylor Park Project which <br />increase exports from the basin were also evaluated during the study from <br />the standpoint of technical feasibility and cost. However, environmental <br />impacts were addressed for the 42,000 af yield concept only. <br /> <br />The Needle Point No. 3 pumped-storage project utilizes the existing <br />Morrow Point Reservoir as its lower reservoir and would include the <br />construction of an upper reservoir on the north canyon rim with a tunnel <br />connecting the two reservoirs. The power house would be located <br />underground, This project would result in daily fluctuations of about 10 <br />feet in Morrow Point Reservoir. This would adversely affect both <br />recreation use of the reservoir and aesthetics. Fishing is not a <br />significant activity at this reservoir at present and impacts to the <br />fishery are considered to be minor. <br /> <br />S-10 <br />
