28. Pine River - Bavfield Ditch Comoanv - Siphon Reolacement Proiect
Authorization: Construction Fund County: La Plata
Water Source: Vallecito Reservoir Project Yield: 8,866 ac.ft.
Terms of Loan: $297,000 @2.75% for 30 years Project Type: Siphon Replacement

PRBDC provides irrigation water to a 2,596-acre service area in La Plata County, generally south of the Town of
Bayfield. The Pine River Bayfield Ditch is a lateral extending off of the Schroder Ditch and is a carrier ditch for
shareholders owning Pine River water rights and Pine River Irrigation District water shares (Vallecito Reservoir).
The PRBDC headgate is located east of the Town of Bay field, above Beaver Creek. From the headgate, the ditch
flows through a concrete flume and into the Beaver Creek siphon, a 32-inch diameter steel pipe siphon, 2300 feet in
length, dropping an estimated 100 feet in elevation, as it runs under Beaver Creek. The current siphon was built in
1955-1957, with a design life of30 years, and is in deteriorated condition. The steel has oxidized to the point
where the pipe walls have thinned in many places beyond repair. A new 30-inch PVC pipe, designed by the
Durango NRCS Office to carry 37 cfs, will replace the existing siphon. NRCS has completed the design and the
project was bid in October of 2004. The Company is reviewing the bids and are anticipating award the contract to
Gosney and Sons, Bayfield, Colorado. The total construction costs have increased from $267,000 to $307,000.
The Company requested an additional $30,000 in loan funds at the November 2004 Board Meeting, which was
approved by the Board. Project construction has commenced and 95% of the pipe has been laid. The Contractor
is currently constructing the concrete inlet and outlet structures with project completion scheduled for June of2005. .
