The outlet works considered are a <br />thirty-six inch (3611.) and forty-two inch (4211.) <br />reinforced concrete pipe. The size is optional <br />based on the owners future demands and preference. <br />Either the 3611. or 4211. outlet will provide the <br />expected downstream needs for the next 40 years. <br />Both sizes also meet the minimum drawdown rate <br />required by the state Engineer. The pipe will be <br />bedded on concrete and will have seepage collars <br />at approximately twenty to thirty foot (20 '-30') <br />intervals. The inlet will be a simple headwall <br />arrangement, and the outlet end will include an <br />energy dissipater and a Parshall flume to measure <br />flows. The wetwell will be cast-in-place concrete <br />with a control gate similar to the existing <br />arrangement. A more sophisticated outlet works is <br />not considered necessary for a dam this size with <br />the storage capacity available. <br />Spillway. The emergency spillway will be located <br />near the right a~utment of the dam as shown on <br /> <br />V-8 <br />
