Sources of Construction Materials <br /> <br />The required construction materials for building the dams, <br />pumping plants, and canals would include impervious and pervious earth <br />fill, riprap, concrete aggregate, and ready-mix concrete, Table A-lO <br />lists the quantities of materials required for the storage d8llls, and <br />Figures A-9 and A-lO show the location o~ the earthfill and riprap <br />materials to be used, <br /> <br />Ridges Basin Dam <br />Southern Ute Dam <br />Total <br /> <br />Table A-IO <br />Materials required for project dams <br />Quantity (cubic yards) <br />Impervious Pervious <br />2,600,000 4,970,000 <br />1,900,000 680,000 <br />4,500,000 5,650,000 <br /> <br />Riprap <br />29,000 <br />43,000 <br />72 , 000 <br /> <br />The impervious materials for both dams would be available below <br />the maximum water level of the respective reservoirs. The impervious <br />materials for lining the Dry Side Canal would be obtained along the canal <br />alignment, The impervious materials for lining the New Mexico Irrigation <br />Canal would be obtained from along the canal alignment and from below the <br />maximum water level of Southern Ute Reservoir and hauled over existing <br />adequate roads for a maximum of 3 miles, Impervious fill material for <br />the La Plata and Southern Ute Diversion D8IIIS would be obtained from lean <br />clay deposits adjacent to the La Plata River, On completion of removal <br />activities, all of the areas would be shaped to conform with the sur- <br />rounding terrain, and those outside the reservoir basins would, in <br />addition, be covered with topsoil and then seeded. <br /> <br />Pervious material for construction of Ridges Basin Dam would <br />come from gravel deposits along the Animas River 3.5 miles southeast <br /> <br />A-26 <br />
