It is <br /> <br /> <br />estimated that the delivery efficiency of the South Platte Ditch is about <br /> <br /> <br />67 percent. Most of the loss is due to seepage. <br /> <br />Farmers Pawnee Ditch. The Farmers Pawnee Ditch diverts from the river <br /> <br /> <br />6.2 miles downstream from the Balzac gaging station and serves about 10,600 <br /> <br /> <br />acres of irrigated land on the north side of the river. A detailed study <br /> <br /> <br />of this ditch system nearly 10 years ago (Bittinger & Associates, 1969) <br /> <br /> <br />showed a high percentage of the Farmers Pawnee Company stockholders also <br /> <br />had irrigation wells as a supplemental source of water. In addition, <br /> <br /> <br />slightly over 900 acres within the ditch service area were being irrigated <br /> <br /> <br />from ground water only. <br /> <br />The average annual diversion of river water by the Farmers Pawnee <br /> <br /> <br />Ditch during the 1947 through 1961 study period was 26,200 acre-feet. The <br /> <br /> <br />lowest annual diversion was 19,100 acre-feet in 1960 and the greatest was <br /> <br /> <br />37,000 acre-feet in 1948. It is estimated that the system delivers about <br /> <br /> <br />65 percent of the amount diverted. Most of the loss is due to seepage <br /> <br /> <br />from the ditch, <br /> <br />Davis Bros, Ditch, The Davis Bros. Ditch is a relatively short <br /> <br /> <br />ditch which diverts from the river 7.0 miles downstream from the Balzac <br /> <br /> <br />gaging station. It serves about 2,000 acres of irrigated land within 1.5 <br /> <br /> <br />miles of the river. The average annual diversion by the Davis Bros. Ditch <br /> <br /> <br />during the 1947 through 1961 study period was 3,900 acre-feet, ranging from <br /> <br /> <br />a minimum of 2,700 acre-feet in 1955 to a maximum of 5,400 acre-feet in <br /> <br /> <br />1948. It is estimated that the Davis Bros. Ditch delivers at least 75 <br /> <br /> <br />percent of the water diverted to farm turnouts. <br /> <br />Schneider Ditch. The Schneider Ditch diverts from the river 11.8 miles <br /> <br /> <br />downstream from the Balzac gaging station and serves about 2,400 acres of <br /> <br /> <br />irrigated land on the south side of the river, The average annual diversion <br /> <br /> <br />by the Schneider Ditch during the IS-year study period was 8,600 acre-feet. <br /> <br /> <br />The smallest annual diversion was 5,600 acre-feet in 1957 and the largest <br /> <br /> <br />was 11,200 acre-feet in 1950. The Schneider Ditch diverted about 1,000 <br /> <br /> <br />acre-feet more river water during the drought year of 1977 than the IS-year <br /> <br />-38- <br />
