From The Loveland Reporter-Herald (Carina Julig):
Montana-based Barnard Construction Inc. has been selected by the board of the Northern Colorado Water Conservancy District to build the Chimney Hollow Reservoir dam west of Carter Lake, the district announced in a press release Friday.
The Bozeman firm will enter into a $485.4 million contract to build the dam for the 90,000-acre-foot reservoir. The company has previous experience working on water infrastructure projects, including the Keeyask Generating Station in Manitoba and a reservoir in central Florida.
The firm was chosen from two price bids because it had previous experience with similar dams, had a strong safety record and offered the best value for its work, Northern Water spokesperson Jeff Stahla said…
Construction could begin as early as May, the release said, and is expected to take four years. The material for the dam will be quarried from the property that will house the reservoir…
Barnard Construction will also build a 40-foot-tall saddle dam at the south end of the valley, opposite from the main dam at the north end, which will significantly increase the amount of water that the reservoir will be able to store.
As part of the permitting process for Chimney Hollow, Northern Water is also building the $18 million Colorado River Connectivity Channel in Grand County to the west of the Continental Divide. The channel is an environmental enhancement and mitigation project that will connect ecosystems above and below the Windy Gap Reservoir, just west of Granby.
