<br />East Fork Mutual Ditch Company <br />January 27, 2004 <br /> <br />Agenda Item 14b. <br /> <br />The East Fork Mutuallrriaation ComDanv <br />The EFMIC is a mutual ditch company and a non-profit corporation registered in the State of <br />Colorado. There are 7 shareholders and 1,000 shares of stock. The EFMIC has the power to <br />set annual assessments to be paid by the shareholders, the power to cut off water deliveries to <br />shareholders that fail to pay their assessments, and the power to offer stock for sale to other <br />shareholders. <br /> <br />Water Riahts <br />The source of water for the Company is direct flow water rights from the East Fork of <br />Troublesome Creek. Water diverted at the Troublesome Creek headgate consists of a 75 cfs <br />peak flow with an August 5, 1959 appropriation. Records from the State Engineer's Office <br />indicate an average annual diversion of 8,000 acre-feet. <br /> <br />Proiect DescriDtion <br /> <br />Work Comoleted: <br /> <br />Due to a slide that occurred in the summer of 2003 the Company was forced to make <br />emergency improvements to their system. Based on evaluation of the site it was believed that <br />the failure was attributed to soil saturation when running ditch water and the failure of those <br />soils given the steepness of the adjacent slope. <br /> <br />The Company elected to repair the area by enclosing 1,060 linear feet of ditch with a 60-inch <br />diameter corrugated metal pipe. Within the new piped section of ditch the Company also had <br />to address two failed slope areas. The Company hired the services of Soil Nail Launchers, <br />Inc., Grand Junction, Colorado to evaluate the site and to propose a remediation plan. Based <br />on the Contractors review and recommendation the Company elected to stabilize the two areas <br />by driving steel rods (soil nail launching) approximately 15-feet in length in a grid pattern. The <br />soil nails would connect to the stable underlying slope, therefore restricting the failed areas <br />from becoming any larger. This stabilization effort, however, would require additional slope <br />work in the future. <br /> <br />Installation of 1,060 linear feet of 60-inch diameter corrugated pipe = $63,924.35 <br />Stabilization of failed slope areas = $38,000.00 <br /> <br />Work In Proaress: <br /> <br />Upon completion of the improvements described above, the Company put the irrigation system <br />back in operation. Towards the end of the irrigation season, it was discovered that a number <br />of the pipe joints were beginning to leak, which in the long term could compromise the integrity <br />of the adjacent slope and increase the chance of another slope failure. Furthermore, the <br />success of providing additional slope stabilization work to the previous failed slope areas would <br />be greatly compromised as well. <br /> <br />The following alternatives were evaluated: <br /> <br />2 <br />
