A 471-foot-high dam stands finished in Boulder County, yet a court order has prevented it from holding additional water.
That’s even though the dam’s builders long ago secured the required permits.
Now, as The Gazette’s news affiliate Colorado Politics reports, the U.S.
Court of Appeals for the 10th Circuit is casting doubt on whether the trial court that issued the injunction had properly decided the case.
It turns out the trial judge might have just been punishing Denver Water for proceeding with the project — which was duly permitted by multiple government agencies.
The case stems from a lawsuit filed by activists with Save the Colorado, the Sierra Club, WildEarth Guardians and other environmental groups.
They claimed that permits issued to Denver Water by the U.S.
Army Corps of Engineers for raising the existing dam’s height and expanding the reservoir it created violated the Clean Water Act, Endangered Species Act and National Environmental Policy Act.
Denver Water supplies water to 1.5 million people in the Denver metro area — 25% of the state’s population.
It had secured the Army Corps’ permission alongside a license modification from the Federal Energy Regulatory Commission, since Gross Dam generates clean hydropower, and a land-use permit from Boulder County.
All three entities signed off on the project, which had the blessing of the state’s political establishment and, for a while, even environmentalists.
Denver Water had every reason to proceed with the 23-year project until enviro-lawyers interfered, exploiting provisions of federal law passed long ago.
In U.S.
District Court Senior Judge Christine Arguello, they found a willing ear.
Arguello’s October 2024 ruling held that the Army Corps wrongfully eliminated alternatives that avoided disturbing wetlands and improperly combined two distinct goals in violation of the Clean Water Act and National Environmental Policy Act.
She later modified her order to account for dam safety, permitting construction to proceed raising the dam’s height.
But her order still barred the reservoir’s expansion — mooting the dam project’s purpose.
At the time, Denver Water called the decision “irrational.”
Last week, during oral argument before the 10th Circuit court, three appellate judges seemed to take a similar view.
“The district court, it seemed, punished the other side for continuing their construction,” said Chief Judge Jerome Holmes.
The plaintiffs denied that it was punitive because “there was nothing requiring them to move forward.”
“Why wouldn’t they?
There was nothing stopping them,” Judge Nancy Moritz interjected.
“And yet, the court seemed to be punishing them for that.”
Moritz wondered how the Corps could weigh reasonable alternatives now that the dam is built.
“There’s only one,” she said.
“The Corps’ job is done,” added Judge Timothy Tymkovich.
“I just don’t see what’s left.”
If Arguello’s ruling stands, the much-needed expansion of Gross Reservoir won’t be the only casualty.
It also will be the projects that come after.
That’s why Aurora, the South Metro Water Supply Authority and even Pueblo Water took Denver Water’s side in court filings.
Arguello’s standard would force builders to “second-guess the decision-making of the federal permitting agency entitled to deference lest the project proponent proceed with construction under a ‘questionably valid permit,’” their attorneys wrote.
Colorado’s water supply is genuinely tight.
Demand isn’t going away.
Gross is 53% full against a 95% historical average.
The expansion is meant to store more water for a growing metro area.
Ratepayers are paying for it.
The 10th Circuit has yet to rule.
But its questions suggest the judges recognize obstruction when they see it — and that Coloradans are footing the bill.
