Antero Reservoir to be drained for drought management

Denver Water, in coordination with Colorado Parks and Wildlife, will close Antero Reservoir on May 1st to drain the reservoir to save water supply during the ongoing drought.

Antero Reservoir has the highest evaporation rate of any of Denver Water’s reservoirs, so draining and storing the water in Cheesman and Eleven Mile reservoirs will reduce system evaporation losses by about 4,000 acre-feet.

“We’re exploring as many ways as possible to be efficient with our water supply,” said Dave Bennett, water resource manager for Denver Water. “Antero is a drought reservoir designed to provide water to our customers during a severe drought. Moving water from Antero to Cheesman will allow us to make the water available for our customers and reduce evaporation losses to our system.

Denver Water is working closely with Colorado Parks and Wildlife to minimize the loss of fish during the drain and to allow the public to use the reservoir before it closes.

- Beginning Wednesday, March 20, the bag and possession limit on trout at Antero will be increased from two to eight fish with no minimum size restriction. All other fishing regulations apply.

- Immediately after the ice has melted off the reservoir, CPW staff will trap and relocate spawning trout. Once the fish have moved off the shoreline and inlet areas, the draining of the reservoir will increase significantly. CPW staff will install a series of screens below the reservoir to capture fish as they leave the reservoir.

- In March, the standard recreation regulations apply.
> South: Open 24 hours a day and camping is permitted.
> North: Open from a half-hour before sunrise to a half-hour after sunset.

- Beginning in April, Antero Reservoir will be open for recreational use from a half-hour before sunrise to a half-hour after sunset. No camping will be permitted. After the ice has melted, only hand-launched vessels will be allowed. No trailered boats will be permitted. Recreation will cease May 1st.

Drought conditions will determine when the reservoir can be refilled. The reservoir was also taken out of service to assist with water management during the drought that began in 2002.
