Antero Reservoir Closing; Fish Salvage Underway

Antero Reservoir (Colorado Parks & Wildlife

Antero Reservoir, one of the two "saucer" reservoirs in South Park, as I like to think of them, is being drained to save water in the current drought. (The other is Spinney Mountain Res.)

Denver Water announced Monday it will drain and close South Park’s Antero Reservoir fishing and camping spot to avoid critical evaporation losses in a tinder-dry season. 

The agency serving 1.5 million Front Range customers will send Antero’s reserve down the South Platte River to Cheesman Reservoir and close the recreation area to the public for the first time since the severe 2002 drought.

The move will keep 5,000 acre-feet of water from evaporating in summer heat about one-quarter of the reservoir’s capacity. In a normal runoff year, that 5,000 acre-feet would easily be made up by snowmelt, but Denver has declared this year’s snowpack the lowest in recorded history in its resource areas. 

Colorado Parks and Wildlife has announced a "no limits" fish-salvage operation.

All . . . regulations, including a valid Colorado fishing license and legal methods of take, will be enforced. Motorized boating and commercialized fishing will not be allowed. Hand-launched vessels and shoreline angling are permitted.  

After May 13, no public access for camping or anything.

Two Buttes Res. in SE Colorado was recently drained too. Maybe the El Niño winter that is supposed to be coming will refill it.
