County: Weld
Project Yield: 1,200 acre-fcet
Project Type: Reservoir Rehabilitation

Owl Creek Reservoir is located approximately 6 miles east and 3 miles north of the Town of Ault. The
reservoir was originally constructed in 1896 to store water for irrigation. The dam was constructed of
granular material, and over the years has suffered structural damage due to seepage. Given the condition
of the dam embankment and the potential for failure, the dam was intentionally breached in 1983. The
proposed project involves rehabilitating the existing dam embankment, the construction of a controlled
outlet structure, and the construction of an emergency spillway. The project was bid in the fall of2oo3.
The Reservoir Company is currently exploring its options increasing the dredging quantity to obtain its
full storage decree of 1,750 acre-feet. The Company is considering applying for additional funds from
the Board to achieve the full reservoir capacity. Additionally, the Company will be requesting a time
extension to complete the work.

The Pine River Irrigation District operates Vallecito Reservoir on the Pine River located approximately 15
miles north of the Town ofBayfield. The eastern half of La Plata County is considered a water critical area,
meaning that all of the water in the basin is used during certain periods. Most of the people in this area are
utilizing groundwater resources that have limited quantity and are of relative poor quality. The purpose of
the project is to provide a rural water system that is adequate in quantity and quality to the water critical areas
in La Plata County. The overall project has many components, however, this particular loan is for diverting
water from Vallecito Reservoir to a pressurized treatment plant The proposed project involves tapping into
the existing outlet tunnel, constructing a 500 foot pipeline to convey water to the treatment plant, a bridge
over the spillway chute, and a pump when the reservoir water level is low or to pressurize the treatment plant.
