<br />" <br /> <br />DUJ~n~ <br />.~ ~.~n <br /> <br />. <br /> <br />Farmers (Peoples) Ditch, The Farmers Ditch diverts from the river <br /> <br /> <br />28.7 miles downstream from the Balzac gaging station and serves a small <br /> <br /> <br />acreage (probably less than 400 acres) on the south side of the river <br /> <br /> <br />within a short distance of the river, The average annual diversion of <br /> <br /> <br />river water during the IS-year study period was 1,800 acre-feet, The <br /> <br /> <br />lowest annual diversion was 600 acre-feet in 1959 and the largest was <br /> <br /> <br />2,900 acre-feet in 1951. The first 1/2 mile of the 5.3-mile ditch loses <br /> <br /> <br />considerable water, but the remaining portion is not large. The overall <br /> <br />efficiency of delivery by the Farmers Ditch is estimated to be about 80 <br /> <br /> <br />percent. <br /> <br />. <br /> <br />Iliff and Platte Valley Canal. The Iliff and Platte Valley Canal <br /> <br /> <br />diverts from the river 31,7 miles downstream from the Balzac gaging station <br /> <br /> <br />and serves about 10,000 acres of irrigated land on the north side of the <br /> <br /> <br />river. The ditch follows the north edge of the alluvium for a distance <br /> <br /> <br />of about 35 miles. Because of its position, it picks up runoff and <br /> <br /> <br />seepage from land above irrigated from the North Sterling Reservoir Outlet <br /> <br /> <br />Canal and its laterals. During the IS-year study period the Iliff and <br /> <br /> <br />Platte Valley Canal diverted an average of 18,500 acre-feet ranging from <br /> <br /> <br />a minimum of 14,000 acre-feet in 1958 to a maximum of 23,000 acre-feet in <br /> <br /> <br />1948. The Iliff and Platte Valley Ditch seepage losses are quite variable <br /> <br /> <br />along its length, but an overall delivery efficiency of about 80 percent <br /> <br /> <br />is estimated for the system. <br /> <br />Lone Tree Ditch. The Lone Tree Ditch diverts from the river 35.1 <br /> <br /> <br />miles downstream from the Balzac gaging station and serves approximately <br /> <br />1,000 acres of irrigated area on the south side of the river, all within <br /> <br /> <br />a mile of the river. The average annual diversion by the Lone Tree Ditch <br /> <br /> <br />during the IS-year study period was 3,800 acre-feet, The lowest annual <br /> <br /> <br />diversion was 1,100 acre-feet in 1959 and the greatest was 6,500 acre-feet <br /> <br /> <br />in 1954. It is estimated that the delivery efficiency of the Lone Tree <br /> <br />Ditch is about 75 percent. <br /> <br />Powell Ditch. The Powell Ditch diverts from the river 39.2 miles <br /> <br />. <br /> <br />downstream from the Balzac gaging station and irrigates about 2,200 acres <br /> <br /> <br />on the north side of the river. The average annual diversion of river <br /> <br /> <br />water during the IS-year study period was 4,400 acre-feet, The lowest <br /> <br />-41- <br />
