Larimer and Weld Ditch, and to refinance the cost of 3 check structures constructed in 2002 along the ditch. The new
check structures will consist of Obermeyer pneumatically operated gates to automatically check and control the ditch. The
gates are opened and closed by a 12-volt DC power air pump, which inflates a durahle rubber bladder on the downstream
side of the gate to raise and lower the gate. Smith Geotechnical has completed the final design plans and the project has

14. Upper Surface Creek Domestic Water Users - Raw Water Line
Authorization: Severance Tax Trust Fund County: Delta
Water Source: Surface Creek Project Yield: 264 ad\.
Tenns of Loan: $162,180@3.25%for20years Project Type: Raw Water Line

Upper Surface Creek is a rural domestic water provider serving a 40 square mile area on the south side of the
Grand Mesa. They currently serve 770 water customers and provide an average of 86 million gallons of water per year
(264 AF). Upper Surface Creek currently relies on the Town of Cedaredge for water treatment, which does not have any
additional capacity to serve the future needs of the Surface Creek Users. The Surface Creek Users are now in the process of
constructing their own water treatment facility with direct flow from surface creek. This project involves the construction
of the 15" PYC raw water line to the treatment plant, the construction of a diversion structure on Surface Creek, and a
concrete pipeline intake with screening and sedimentation. The project is currently under construction and is anticipated to
be complete by November of 2004.

15. Willow Heights Irrigation Company - Dual Water System
Authorization: Construction Fund County: Delta
Water Source: Leroux Creek Project Yield: 257 ad\.
Tenns of Loan: $115,000 @3.75% for 30 years Project Type: Dual Water System

WHIC owns and operates an existing piped irrigation system located in the Willow Heights Subdivision and Duke
Hill community in the Town of Hotchkiss. The system was constructed in 1976, and water is obtained through the Duke
Ditch, which diverts water from Leroux Creek. Water is supplied to about 95 residential lots and a Town park. The total
irrigated area is about 60 acres, and primarily use is to irrigate lawns and gardens. The system consists of a headgate,
approximately 6000 lineal feet of main distribution piping (10",8" and 6"), and approximately 3000 feet offateral piping.
The original piping was a lightweight plastic pipe, and improper backfilling resulted in crushed pipes in some areas, and
significant plugging problems. As a result of the blockages, and teduced flow due to mineral deposits, the overall flow
capacity is less than 1/3 of the original. The project involves installing all new distribution lines and lateral tap lines, along
with cleanouts and isolation valves. The new pipes will be installed over the top of the existing system but at a standard
depth of 22 - 30". The piping will be heavier PYC, located above the existing pipe, but offset several feet to eliminate
