April 23, 2025

A federal judge on Tuesday ordered Denver Water to share information with the environmental groups who successfully challenged a reservoir expansion project in Boulder County, as both sides prepare for a hearing to determine how much additional construction is necessary to stabilize the structure…Days later, Arguello allowed for necessary construction to temporarily resume, and the U.S. Court of Appeals for the 10th Circuit has since extended that window while it reviews Arguello’s order. However, last Wednesday, the groups that challenged the project’s legality asked Arguello to intervene on another issue related to the upcoming hearing about how much stabilizing work is warranted…In response to the groups’ questions about risk management plans, spillway capacity and failure modes — plus a request for project documents — Denver Water told the petitioners that disclosure “poses Dam security risks.”

“The fact remains that Denver Water is the only party that currently has available to it extensive documentation that bears directly on the specific safety issues that this Court ordered all parties to address at the hearing,” the environmental groups added in their court filing.
