Antero Dam Rehabilitation Project

Bringing a century-old dam up to today's standards

Antero, a popular place for recreation in Park County, reopened for modified camping and fishing in June 2017. Denver Water had to drain the reservoir in 2015 for an extensive project to rehabilitate Antero Dam.

Why it's important

Antero Dam is fully operational, but it’s old. The dam has been in service for more than 100 years, and this rehab work helps ensure the dam can operate for another 100 years. That meant a big, but necessary, project to bring the dam more in line with today's engineering and safety standards.

How it impacts recreation

Anglers and campers can rejoice, because the reservoir, a popular recreation spot, reopened for camping and modified fishing on June 5. Recreationists should still expect to see construction activity on the south side of the reservoir as Denver Water works on the final phase of the dam rehabilitation project.

Anticipated timeline

With work on the dam and spillway wrapped up, the project is in its final phase: electrical and mechanical upgrades to the outlet structure and headquarters facilities. We anticipate finishing the work and receiving the state's approval by the end of 2017.
