<br /> <br /> <br />i <br /> <br />. <br /> <br />. <br /> <br />new Riverside Canal with supplemental pumping from Jacksen Lake <br />alternate. You will recall that our February site selectien study <br />included meving the present Jackson Lake service to Narrows <br />Reservoir, vacating that reservoir site for other use or abandonment. <br />With this .site available, both alternates (a) and (b) make use of <br />it to serve the Riverside area. <br /> <br />Alternate (a) provides a new canal from the Bijou diversion dam on <br />the South Platte River to the Riverside outlet canal just below <br />Riverside Reservoir. Riverside Reservoir and the existing supply <br />canal would be abandoned. The new canal would have a capacity of <br />420 cfs and be 7.5 miles long. The Riverside direct flow right <br />would be transferred downstream te the Bijou diversion dam and the <br />storage right te Narrows Dam. The canal would use the left side of <br />the Bijou diversion dam to divert water under direct flow rights and <br />to divert water exchanged from Narrows upstream to this point. In <br />addition, Jackson Lake would be filled by exchanges of Riverside <br />storage water. This water would be pumped during the irrigation <br />season to the Riverside Canal from the west side of Jackson Lake. <br />The entire construction cost would be about $2,000,000; the annual <br />operation, maintenance, replacement and pumping cost using Missouri <br />River Basin power rates would be $2l,500; the total annual cost would <br />be $60,700 and the incremental cost per acre-foot $~~.~;: <br /> <br />Costs of the individual features are given on Table 3 of the hand out. <br />Our earlier studies showed that Riverside had average shortages of <br />4l,600 acre-feet annually. This plan would reduce these to 7,500 <br />acre-feet annually, for the study period 1952-l957. In the worst <br />year 1956 the shortages would be 3l,6bOacre-feet. The amount of <br />Narrows Project water allotted to Riverside by this plan would be <br />29,aooacre-feet. The additional capacity in Narrows Reservoir <br />required to operate the plan would be 37,800 acre-fee~ Of the total <br />amount of 61,500 acre-feet annually delivered to the Riverside area, <br />/~~&> T,OO~ acre-feet would be pumped through an average head of 40 feet, <br />and ~,500 acre-feet would be supplied by gravity service. <br />~11, <br />The cost to Riverside farmers would be based.on the repayment capacity <br />generated by the additional water and so would be the same by any <br />service plan. The additional subSidy required from Missouri River <br />Basin power would, of course, be more, <br /> <br />By alternate (b) the Jackson Lake pump plan, the entire l' <br />Rive be transported to Jackson Lake v' e existing <br />Jackson Lake supp nal. The Rivers servoir and canals upstream <br />from Jackson Lake would b ned. Direct flows and exchanges of <br />Narrows Projec would be de 1 d to Jackson Lake in the <br />irrigat season and pumped directly to e Illverside Canal. In <br />add' on, Jackson Lake would be filled in the winter'and 5S,GOO acre- <br /> <br />2 <br /> <br />
