A <br />2,760-foot-long buried discharge line would extend from the plant to the <br />canal, Each pumping unit would be equipped with a fish screen so that <br />fish larger than 2-inches long would not be drawn into the plant. A <br />switchyard and parking lot would be constructed adjacent to the plant. <br /> <br />(e) Dry Side Canal and Long Hollow Tunnel <br /> <br />The Dry Side Canal, which would extend 27,5 miles <br />from Ridges Basin Pumping Plant to the western project land, would be <br />earth lined except for about 0.9 mile that would be concrete-lined, 3.2 <br />miles formed by the Long Hollow Tunnel, and 3,2 miles of other inline <br />structures. Some of the canal's associated structures would be bridges <br />(some for game crossings), a pipe section at a road crossing, crossdrain- <br />age culverts, siphons, and wasteway structures. <br /> <br />'. <br />i; <br />if; <br />~j <br />~ <br />:it <br />, <br /> <br />Consistent with the capacity of Ridges Basin Pumping <br />Plant, the Dry Side Canal would have an initial capacity of about 700 cfs <br />and a water depth of 7,6 feet at capacity, gradually diminishing to 230 <br />cfs with a water depth of 4.8 feet, The Long Hollow Tunnel, which would <br />be bored through the divide that separates the Animas and La Plata River <br />drainages, would be concrete-lined with a finished diameter of 10.5 <br />feet. The tunnel's spoil material would be used to construct a portion of <br />the canal west of the tunnel. Construction access to the canal and <br />tunnel would be from existing roads. An operation and maintenance road <br />would be constructed along the crest of the left canal bank and would be <br />permanently maintained after construction. Livestock fencil\g about 4 <br />feet high would be installed on both sides of the estimated 20 miles of <br />earth-lined canal to keep out livestock. The estimated 0.9 mile of <br />concrete-lined canal would also be fenced on both sides with 8-foot-high <br />fencing to prevent the entry of wildlife, particularly deer. <br /> <br />A total of 56,262 acres of project land would be <br />served from the canal by means of turnouts and seven lateral systems <br />consisting of about 162,1 miles of buried pressuri~ed pipe. Four of the <br />lateral systems, serving about 75 percent of the land would be gravity <br />fed. The gradient between the canal turnouts and the land to be served <br />is sufficient to develop pressure in the pipe lateral for sprinkler <br />irrigation. To develop sufficient water' pressure in each of the three <br />remaining lateral systems, however, three pumping plants (shown on <br />the general map) would be constructed to lift water from the canal to <br />elevated steel tanks standing from about 145 to 220 feet above the ground <br />surface. Each plant would be fully automatic and occupy a fenced area of <br />about 5/8 acre. Additional information for each pumping plant is <br />provided in Table A-3, and a typical pumping plant is shown in Figure <br />A-4. <br /> <br />, <br />J.~ <br /> <br />:.,-, <br />Jt <br /> <br />" <br />~:} <br />'p. <br /> <br />,~, <br />~ <br />;~i <br />~-.;_. <br /> <br />A-l2 <br />
