8. Owl Creek Reservoir Company - Reservoir Rehabilitation

Authorization: Construction Fund
Water Source: Owl Creek Basin
Terms of Loan: $1,125,000 @2.75% for 30-years

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

Owl Creek Reservoir is located approximately 6 miles east and 3 miles north of the Town of Au\t. 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 of2003.
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 has amended the loan
contract for a I-year time extension to complete the work. The Company is also researching the
possibility of utilizing Owl Creek Reservoir as storage facility from flows outside of Owl Creek. This
could be accomplished by pumping water from the Larimer Weld Canal, located approximately % of a
mile downstream of the reservoir.
