PREDC provides irrigation water to a 2,596-acre service area in La Plata County,
generally south of the Town ofBayfield. The Pine River Bayfield Ditch is a lateral extending
off ofthe Schroder Ditch and is a carrier ditch for shareholders owning Pine River water rights
and Pine River Irrigation District water shares (Vallecito Reservoir). The PREDC headgate is
located east of the Town ofBayfie1d, 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 ono 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 PVCpipe, 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 of2004.. The Company is reviewing the bids and are_anticipating awarq the contract to

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

The Buffalo Farms LLC is comprised of a number of farms with a total combined
irrigated land of 1,000 acres. The farms utilized 11 existing wells to irrigate the 1,000 acres,
growing com, alfalfa, beans, and wheat. The 11 wells are currently being augmented under the
Logan Well Users plan. The proposed project consists of 1 recharge well at the river, and
6,000-ft. of pipe to a 22 acre existing recharge site. The proposed project will eliminate the need
for the Development to be under the Logan Well Users and will provide sufficient augmentation
credits to cover their depletion from the 11 wells. The project is currently under construction
and is anticipated to be complete by June of 2005.
