Two opportunities exist to correct this <br />condition to tolerable limits. They are: <br /> <br />(1) Reorganizing irrigation systems to eliminate unnecessary <br />canals and laterals, and <br /> <br />(2) Lining canals in areas of high seepage losses. <br /> <br />Thirty-three systems with problems in the North Platte Valley have <br />1,080 miles of distribution canals. In many places canals run close <br />together. It is estimated that 140 miles of canals could be eliminated <br />by the reorganization of 11 systems. This would reduce the canal mileage <br />of these systems by about 13 percent. <br /> <br />41 <br />
