Director, CWCB TO: Colorado Water Conservation Board Members FROM: John Van Sciver DATE: November 11, 1996 SUBJECT: Agenda Item Sb., November 25-26, 1996, Board Meeting-- Mancos Water Conservancy District Approval of an Emergency Loan in amount of $62,500. to rehabilitate a portion of the inlet canal to the Jackson Gulch Reservoir. ~:~ BACKGROUND The Mancos Water Conservancy District (located in Montezuma County), has submitted an application for an emergency loan to rehabilitate 500 feet of the inlet canal. They request a loan of $62,500 (50% of the estimated total project cost of $125,000). The damaged portion of canal is located about 5 miles north of Mancos. The canal was constructed in 1948, and the slide occurred in an earth portion of the channel. Evidence of movement was first noted in 1994. The area was inspected by the USBR, and minor repairs were made by the District, per Bureau recommendations. The area was monitored regularly by the Bureau and by the District, but was not considered a serious problem until early fall 1996, At that time the District attempted to run water through the canal, and a major slide developed. The inlet canal can not be used until this slide area is rehabilitated. Preliminary engineering design work has been completed by the Company's engineer and contractor. The USBR has completed preliminary feasibility work, and has reviewed the proposed design. All work must conform to USBR standards, since the Bureau is the owner of the project facilities. DISCUSSION The details of this loan were faxed to all board members October 23rd. A follow-up Memo was faxed on October 30,1996. There were no serious issues raised by the CWCB.
