Antero Reservoir to be drained for drought management; bag and possession limit on trout increased

Popular spot for trout fishing closes in May

DENVER - Antero Reservoir will close on May 1 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, said Dave Bennett, water resource manager for Denver Water. Bennett said draining and storing the water in Cheesman and Eleven Mile reservoirs will reduce system evaporation losses by about 4,000 acre-feet.

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.

“We have come up with a plan to successfully remove as many trout out of Antero as possible to stock in other reservoirs in Park County," said Jeff Spohn, aquatic biologist with Colorado Parks and Wildlife (CPW). "On a positive note, the water from Antero will be delivered to Cheesman at a flow rate that will benefit the wild rainbow trout fishery below Eleven Mile Reservoir.

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.

“We have a blueprint on how to successfully rebuild the fishery at Antero,” Spohn said. “We hope to see similar trophy trout fishing that we saw last time the reservoir refilled.

For the rest of March, the standard recreation regulations apply.

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.  Recreational use will stop May 1.

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.
