<br />2.3.2.3 Outlet Works - The outlet works would be the same as <br />Alternative A except longer, The conduit would be sized to <br />accommodate a 200 kw (7200 MJ) hydroelectric plant In the future. <br /> <br />2.3.2.4 Material Sources Approximately 432,000 cubic yards <br />C323,400m3) of material would be needed to construct a larger dam at <br />Taylor Draw. This represents a 60% volume Increase over Alternative A <br />because Reinforced Earth(r) cannot be used for the downstream face. <br />The majority of borrow material would come from the reservoir basin. <br />There, are two borrow areas located outside of the reservoir basin. <br />Figure 2 - 3 shows the location of the borrow areas, Roughly 5 acres <br />(2.0 ha) of Borrow Area E and 20 acres (8.0 ha) of rlprap source would <br />be disturbed. Fill within the White River may be required to complete <br />the access roads but would be removed prior to Inundation. Concrete <br />aggregate would be trucked In from Jensen, Utah. <br /> <br />2.3.3 Reservoir Operation <br /> <br />2.3.3.1 Alternative B would operate the same as Alternative A except <br />a larger quantity of water would be stored for future release, <br />regulation, and use, The reservoir, during normal spring runoff, <br />could fill In 5 to 6 days. The outlet works would be operated to <br />regulate the flow over the spillway to maintain a minimum of 1000 cfs <br />(28m3/s) for hydraulic purposes, During the winter when normal flows <br />are less than 1000 cfs (28m3/s) the outlet works would pass the flow <br />of the river to elIminate the problem Ice Jams. Additional water <br />rights would need to be secured to completely fill the reservoir. <br /> <br />2.3.3.2 The comparable firm annual yield for this alternative would <br />be 36,700 AF (45x106m3) and would utilize 25,450 AF C31X106m3) of <br />storage. With the same conditions assumed for Alternative A, the <br />water budget for this alternative would be: <br /> <br />20 <br />
