As Save the Colorado and Denver Water prepare to face off in a federal courtroom Tuesday, water officials across the state are watching the Gross Dam expansion case closely for its environmental impact and its affect on water projects across the West.

Kirk Klancke, a long-time Grand County environmentalist and president of the Colorado River Headwaters Chapter of Trout Unlimited, said a decision that shuts down the $531 million water project, could also shut down 12 years of work on the Fraser River and its tributaries.

Here’s why: Denver Water owns much of the Fraser with water rights dating back more than 100 years. And it is that water that has historically been piped through the Moffat Tunnel near Rollinsville to fill the existing Gross Reservoir. The new water for the expanded reservoir will come largely from that river as well.

A federal judge ruled on Thursday that Denver Water is permanently barred from expanding the reservoir if an emergency stay is not obtained from the 10th Circuit Court of Appeals within 14 days.

The utility provider has been working to increase the height of the Gross Reservoir dam by 131 feet for over a decade. The project broke ground in 2022 and Denver Water says the project is already 60% complete.
