It would be 12 miles long, <br />including about 4 miles of unlined earth sections, 7 miles of earth-lined <br />sections, and 1 mile of concrete bench flume and siphons. <br /> <br />There would be about 15 miles of laterals in the Milk Creek Segment. <br />The largest of these would be the l2-mile-long Iles Lateral, having an <br />initial capacity of 20 second-feet and a terminal capacity of 5 second- <br />feet. <br /> <br />White River Feeder Conduit <br /> <br />The 11.7-mile White River Feeder Conduit would have an initial ca- <br />pacitv of 300 second-feet and a 90-inch diameter from the diversion dam <br />to the Lake Avery Turnout. From the turnout to the Oak Ridge Tunnel, it <br />would have a capacity of 160 second-feet and a diameter of 66 inches. It <br />would be buried and designed to operate year-round. <br /> <br />The Oak Ridge Tunnel would penetrate the ridge between Big Beaver <br />and Little Beaver Valleys at an elevation of 7,030 feet. The tunnel <br />would be about 3,024 feet long. It would be a concrete lined structure <br />of about 7 feet in diameter with a capacity of 160 second-feet. <br /> <br />Yellow Jacket and Oak Ridge Conduits <br /> <br />The Yellow Jacket and Oak Ridge Conduits would be buried pipelines. <br />The Yellow Jacket Conduit would be 15 miles long, have an initial capac- <br />ity of about 125 second-feet, and an initial diameter of 60 inches. The <br />Oak Ridge Conduit would be 9.1 miles long, have an initial diameter of <br />42 inches, and a capacity of 35 second-feet. The size and capacity of <br />each conduit would decrease in size with each successive turnout. About <br />16.7 miles of lateral would be associated with the Yellow Jacket Conduit <br />and about 5.5 with the Oak Ridge Conduit. <br /> <br />Avery Pumping Plant <br /> <br />The Avery Pumping Plant would consist of six electrically operated <br />pumps with a capacity of 160 second-feet at a total design head of 235 <br />feet. <br /> <br />Fish and Wildlife and Recreation Features <br /> <br />Provisions for fish and wildlife and recreation in the plan are <br />described previously under project plan. <br /> <br />Economic aspects <br /> <br />Estimated construction costs for the MOP compromise plan are <br />$79,800,000, considerably less than those needed for the previous plan. <br /> <br />59 <br />
