Northern Water is committed to keeping the public informed as we gather additional information on the discovery of uranium at the Chimney Hollow Reservoir construction site.

The water conveyance system used for delivering water in and out of Chimney Hollow Reservoir is constructed and nearly complete.

Concrete was used in almost every area of the project, including the plinth, spillway, thrust blocks, valve house, tunnel lining, inlet/outlet, tower, staff gauge and more. 

The tallest new dam built in the United States in the last 25 years is now complete. Crews celebrated the huge milestone during an all-site safety meeting on Aug. 7. 

After 1,000 days, 3.3 million work hours and 512 lifts encompassing 200 miles of asphalt paving, a huge milestone was reached on Friday, July 18, as crews placed the final lift of asphalt.

Positive momentum continues to build at Chimney Hollow Open Space with the adoption of Larimer County Natural Resources adaptive management plan.

An important but rarely used piece of infrastructure successfully passed dry testing last month, bringing all dry testing at Chimney Hollow Reservoir to a close.

Many pieces of the plant have already been demobilized, and the remaining pieces will be following suit this month.

“It’s great to be part of such a well-executed project that’s been in planning for a long time. I’m humbled to be part of such a great team," Kugler said.
