<br />(.t:' <br />...... <br />~ <br />-. <br /> <br />BUREAU OF RECLAMATION REPORT <br /> <br />,,;...--: ' <br />... :':",-" ~' <br /> <br />of Big Sandy Creek near the creek's confluence with Green River. The <br />canal, mostly in eartl1 erection, would.. be 52 miles long. TwO' major lat~ <br />erals, with capacities of 90..second-feet and 20 second-feet; would brancn <br />from the canal and assist in serving the Big Sandy area. From the Green <br />River Siphon the East Side Canal would extend southeast about 13 miles <br />to serve benchlands immediately east of the Green River. <br /> <br />The West Side Canal system would include the West Side Canal, Pump <br />Supply Canal, Upper West Side Pump Canal, North Dry Creek Lateral, South <br />Dry Creek Lateral, Dry Creek Pumping Plant, and Lower Pumping Plant. <br />From its heading at the end of the Seedskadee Diversion Canal, the West <br />Side Canal would extend 33 miles down the west bank of the Green River. <br />The canal would have an initial capacity of 653 second,.feet and a termi- <br />nal capacity of 262 second-feet, The capacity would be reduced as diver- <br />sions were made along the canal course, The largest diversion, 214 sec- <br />ond-feet, would be made by the Pump Supply Canal. This canal would head <br />near the crossing of the West Side Canal and Dry Creek and would extend <br />about one-half mile to the Dry Creek Pumping Plant. At the pumping plant <br />176 second-feet of the flow would drop 56 feet through a water turbine <br />into the North and South Dry Creek Laterals for irrigation of low bench- <br />lands. The remaining 38 second-feet would be lifted 93 feet by a turbine. <br />driven pump into the Upper West Side Pump Canal for service of high bench- <br />lands situated above the gravity canal system. The West Side Canal would <br />termin!i-ce at the Lower Pumping Plant where its flow of ~EQ second-feet - . <br />would be divided between the Lower West Side Gravity Canal and the Lower <br />West Side Pump Canal. A turbine would be propelled by 175 second-feet of <br />water in a drop of 46 feet to the gravity canal. The remaining 87 second- <br />feet would be lifted 54 feet by a turbine -driven pump into the pump canal. <br />The Lower West Side Gravity Canal would be 27 miles long and the Lower West <br />Side Pump Canal would be 35 miles long. Both would generally parallel the <br />west bank of the Green River, with the pump canal serving the higher bench. <br />lands. <br /> <br />A lateral distribution system would be constructed to deliver irri- <br />gation water from the canals to project farms, <br /> <br />Drains. Because of the favorable drainage characteristics of project <br />lands, as discussed in a subsequent section on lands, only a simple system <br />of drains would be required. Natural drains would be used to collect drain <br />water from high benches for reuse on lower benches. These would require <br />only slight improvements under project development. A few miles of arti- <br />ficial drains would be constructed across the wider benches and immediately <br />below the steep slopes separating the terraces. <br /> <br />Project Costs <br /> <br />Estimated construction costs of the various project features and <br />detailed engineering data on the features are summarized in the table on <br />the following page. As shown by the table, the construction costs are <br /> <br />4 <br />
