<br />STATE OF COLORADO <br /> <br />Colorado Water Conservation Board <br /> <br />Department of Natural Resources <br />1313 Sherman Street, Room 721 <br />Denver, Colorado 80203 <br />Phone: (303) 866-3441 <br />FAX: (303) 866-4474 <br />www.cwcb.state.co.us <br /> <br /> <br />July 25, 2003 <br /> <br />Bill Owens <br />Governor <br /> <br />Mr. Pat Schumacher, Manager <br />U.S. Bureau of Reclamation <br />Western Colorado Area Office, Four Comers Division <br />835 East Second Avenue, Suite 300 <br />Durango, CO 81301 <br /> <br />Greg E, Walcher <br />Executive Director <br /> <br />Rod Kuharich <br />CWCB Director <br /> <br />Dear Mr. Schumacher: <br /> <br />Dan McAuliffe <br />Deputy Director <br /> <br />I am writing this letter to request assistance from your Technical Assistance to States Program. <br />CWCB recently approved a loan to the Pine River Bayfield Ditch Company located in La Plata <br />County for the replacement of the Beaver Creek Siphon (siphon). The siphon is approximately one- <br />halfmile in length and is located just east of the town of Bayfield, Colorado. It has deteriorated to <br />the point that it is in need of immediate replacement. <br /> <br />The Board of Directors of the Pine River Bayfield Ditch Company (PRBDC Board) have worked <br />closely with Dan Lynn, District Conservationist, Natural Resources Conservation Service (NRCS) <br />and his staff, in Durango, Colorado, to develop a cost estimate and construction design to replace the <br />siphon. Unfortunately, the NRCS recently informed the PRBDC Board that they do not have a <br />geologist available to conduct the geological survey in a timely manner. The PRBDC Board desires <br />to take advantage of the drought to replace the siphon since the Pine River Bayfield Ditch is <br />anticipated to be out of water by mid to late July. <br /> <br />With this letter, we are requesting technical assistance in performing the geological survey from the <br />Bureau of Reclamation. The survey needs to include the following: <br />1) Construction of test pits <br />2) Logging oftest pits approximately every 500 feet along the alignment <br />3) Materials analysis (lab analysis) <br />. Gradations <br />. Atterberg <br />. Moisture Content <br />4) Geologic profile along alignment <br />5) Hydrologic analysis <br />6) Other criteria as deemed appropriate by the NRCS design engineer <br /> <br />We anticipate that the cost ofthis work will range between $5,000 and $10,000. If at all possible, it <br />would be desirable to schedule the survey to begin in early to mid August, 2003. <br /> <br />Flood Protection · Water Supply Plarming and Finance.
