Lochhead <br />Executive Director, DNR <br /> <br />Oaries C. lile, PE <br />Director, eWeB <br /> <br />(UPDATED December 19, 1996) <br /> <br />TO: Colorado Water Conservation Board Members <br /> <br />FROM: John Van Sciver <br /> <br />DATE: November 13, 1996 <br /> <br />SUBJECT: Agenda Item 120., November 25-26, 1996, Board Meeting-- <br />Summit Reservoir and Irrigation Company <br />Approval of a Construction Fund Loan in amount of $600,000 to rehabilitate <br />the Summit Reservoir and Irrigation Company system. <br /> <br />BACKGROUND <br /> <br />The Summit Reservoir and Irrigation Company (SRIC), located in Montezuma County, has <br />submitted an application for a loan to rehabilitate their system, including the Dam on the Summit <br />Reservoir, and the various collection and distribution canals, They requested a loan in the <br />amount of $800K, 100 % of the estimated total project cost. 75% of the total project cost is <br />$600K. <br /> <br />The Summit Reservoir system is located about 35 miles west of Durango, The outlet on the <br />reservoir is inadequate by State Engineer standards, and must be rehabilitated this winter, at a <br />cost of $80,000. The embankment has a high phreatic surface in places, and is prone to leakage <br />when the reservoir is full. <br /> <br />The reservoir is filled primarily from the Lost Canyon diversion canal. This canal passes <br />through the "Rail Road Siphon", which is constructed of wood staves held in place with steel <br />bands. This siphon is a continuing serious maintenance problem, and about $5000 was spent <br />in 1996 alone to make repairs. This siphon is a critical part of the system, The estimated <br />replacement cost is $123,000. <br /> <br />The delivery ditches are in poor condition. In two locations the canal has cut a small canyon, <br />up to 40 feet deep, through private property. Leakage losses are significant, and it is difficult <br />or impossible to deliver water to all users. The estimated cost to rehabilitate the delivery portion <br />of the ditch is about $600K alone. <br />
