Walcher <br />Executive Director <br /> <br />FROM: <br /> <br />John Van Sciver, P.E. <br />Mike Serlet, P.E., Chief <br />Water Supply Planning and Finance Section. <br /> <br />Rod Kuharich <br />eWeB Director <br /> <br />Dan McAuliffe <br />Deputy Director <br /> <br />DATE: March 13, 2003 <br /> <br />SUBJECT: Agenda Item 25a., March 24-26, 2003 Board Meeting <br />Low Line Ditch Company - Loan Increase <br /> <br />Introduction <br />The Low Line Ditch Company (LLDC) is applying for a $65,250 increase in an existing CWCS <br />loan, to rehabilitate its diversion on the South Platte River. The estimated total cost of this project <br />is $72,500. The new total loan amount will be $159,750. Please see the attached project summary <br />and map. <br /> <br />Backaround <br />The LLDC, located in Logan County, operates the Low Line Ditch for the benefit of its <br />shareholders by providing delivery of water for irrigation within a 2,070-acre service area. The <br />system consists of a headgate on the South Platte River at Sterling and about 7 miles of ditch. <br /> <br />In January 2003 the LLDC was approved for a $94,500 CWCS Small Project loan to develop a <br />recharge system that will generate augmentation water to be used to offset the depletions <br />caused by their 13 wells. By generating their own augmentation the LLDC shareholders can <br />protect themselves from possible curtailment and help GASP strengthen its coverage in the <br />same area of the river. <br /> <br />The LLDC has discovered the difference between running the ditch in the summer months, <br />versus running the ditch year round. Recharge systems require that the recharge ponds be <br />filled during the winter months, at rates less than summer diversion rates. The current LLDC <br />diversion does not efficiently divert the required wintertime water, and needs to be rehabilitated. <br />As a positive side effect, summer diversions would also become more efficient. <br /> <br />Feasibilitv Studies <br />Brent Nation, P.E. of Nation Engineering Services, has completed the feasibility study. The report <br />includes an evaluation of alternatives available to rehabilitate the LLDC river diversion structure. <br />
