low level outlet structure and raising the crest of the dam approximately 12-inches. Leonard Rice Consulting Water Engineers completed the feasibility study. Dam improvements are tentatively scheduled for construction in the fall of2003. elO. Town of New Castle - Water Transmission System Authorization: Construction Fund County: Garfield Water Source: Colorado River Project Yield: 400 acre-feet Terms of Loan: $700,000@4.50%for30-yearsProjectType: 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 ofI-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. II. Suvvlv Irrigation Ditch Comllany - Knoth Reservoir Dam Rehabilitation Authorization: Construction Fund County: Boulder- N.E. of Lyons Water Source: St. Vrain Creek Project Yield: 9,500 acre-feet Terms of Loan: $1,700,000 @3.50% for 30-years Project Type: Dam Rehabilitation eThe Supply Irrigation Ditch Company is proposing to rehabilitate the Knoth Reservoir for use as an equalizer, and for storage under a conditional decree for 542 acre-feet. The average annual volume diverted now is 9,500 acre- feet, which will be increased to 10,040 acre-feet with the project improvements in place. The planned improvements include, reshaping the upstream face of the dams and the placement of clay, installation of a toe drain, construction of 200 foot long spillway, placement of rip rap, raising the dam crest on both dams to gage height 30-ft., removal of two abandoned outlets, and the repair of the existing outlet to a good working condition. The proposed improvements are being designed by Smith Geotechnical, of Fort Collins, Colorado, and are planned to be constructed in the fall of2003. 12.
