9. Town of New Castle - Water Transmission System

Authorization: Construction Fund
Water Source: Colorado River
Terms of Loan: $700,000 @4.50% for 30-years

County: Garfield
Project Yield: 400 acre-feet
Project Type: System Rehabilitation

The Town of New Castle is applying for a loan to construct a new diversion structure and
pump station on the Colorado River, and a raw water pipeline to the Town's existing
water treatment facility. Currently the Town's sole source of water supply is a diversion
structure on East Elk Creek, about 3 miles north of town. The Town's water supply is
vulnerable to downstream senior water calls, as well as potential water quality problems
due to sediment and ash runoff from forest fire hazard, as was experienced in 2002. The
proposed project is to construct a small diversion structure on the Colorado River, with
gravity flow to a pump station on the south side ofI-70. From there water would be
pumped to a sedimentation pond on the north side of I-70, and a second pump station
would be used to lift the water to the treatment plant, an elevation increase of about 250
vertical feet. A 12" PVC waterline, 8750 feet in length, would be constructed from the
pump station to the treatment plant. The general pipeline alignment would be initially
along Elk Creek, then following the Town street right-of-way for Midland Avenue, and
then along County Road 245 to the water treatment plant. The system would be
designed to pump 1800 gpm, and each pump station would have two pumps plus one
back-up pump. The project will provide the Town with a reliable alternate water source
during times when diversion from East Elk Creek is prohibited by either water rights
administration or poor water quality. The project was designed by Schmueser Gordon
Meyer, Glenwood Springs, Colorado, and is currently being constructed by Aspen
Earthmover, Carbondale, Colorado. The project is complete. The Town has submitted
their final loan request on the project and has requested a July 1, 2005 substantial
completion date to coincide with their new fiscal year.

10. East Fork Mutual Ditch Company - Ditch Rehabilitation Proiect

Authorization: Severance Tax Trust Fund
Water Source: East Fork Creek
Terms of Loan: $259,860@ 2.50% for 30 yrs.

County: Grand
Project Yield: 8,000 AF
Project Type: Ditch Rehabilitation

The EFMIC owns and operates the East Fork Ditch to deliver direct flow irrigation water
for the benefit of the shareholders. Water is diverted from the East Fork of Troublesome
Creek, located about 10 miles northeast from the Town of Kremmling. The 13-miles of
ditch is open channel that meanders along steep mountain slopes and open pasture land.
In recent years, the Company has experienced slope failures along steep canyon sections,
caused by ditch flows saturating the adjacent soils. This project involves the piping of
approximately 1,060 linear feet of ditch with 60-inch pipe and stabilizing the failed slope
areas. The Company was approved for a revised total loan amount of $377,497 is
September of 2004, due to a change in the method of slope stabilization to be employed.
The slope stabilization work was awarded to Yenter, who commenced construction in
October 2004. The Contractor has completed the slope stabilization, toe drains, and
