The Stokes Gulch Siphon (Siphon) crosses Stokes Gulch adjacent to the Colorado River <br />and is part of the District's Power Canal. The Siphon and Power Canal are owned and operated by <br />the District for the conveyance of water for power generation and irrigation. The Siphon is located <br />two miles east of Palisade along US 6. The Project will replace the existing siphon and is expected <br />to cost $600,000. Construction is scheduled for the winter of 2006. See attached Project Data <br />Sheet for a location map and a project summary. <br /> <br />Backaround <br /> <br />Colorado River water is diverted into the Government Highline Canal (GHC) at the Grand Valley <br />Project Diversion Dam (Roller Dam), about 23 miles northeast of Grand Junction. Water is then <br />diverted into the Power Canal (capacity of 800 cfs) from the GHC approximately five miles <br />downstream of the. Roller Dam. This water passes under the Colorado River in a siphon via the <br />Power Canal to the District's pumping plant (Plant), where it is pumped into the District's Canals No. <br />1 and 2 for distribution to the water users. <br /> <br />The Plant lifts water from the Power Canal to the distribution system. The Plant contains four pump <br />units: two have a combined capacity of 80 cfs and a lift of 41 ft to Canal No.1; two have a <br />combined capacity of 60 cfs with a lift of 130 ft to Canal NO.2. Water is then conveyed to privately <br />owned and operated laterals. <br /> <br />Xcel Energy owns a hydro power plant adjaeent to the Distriet's pumping plant. The hydro power <br />plant operates under a maximum head of 79 feet and has a capaeity of 3,000 kilowatts. The hydro <br /> <br />Flood Protection. Water Supply Planning and Finance.
