Fishing Antero Reservoir: the full guide

The shallow giant

Antero sits at 8,900 feet in South Park: shallow, weed-rich and absurdly fertile, growing rainbows, browns and cutbows faster than anywhere in Colorado. Scuds and callibaetis feed them; float tubes and patience find them. Ice fishing is a winter institution when conditions align.

Growing giants at altitude

Antero's shallow, mineral-rich water grows trout faster than anywhere in Colorado: cutbows and browns gain multiple pounds a year on scud-and-snail buffets. CPW manages it openly as a trophy factory: periodic drainings reset it; the rebound years are legendary.

Float-tube country

Motors run limited and the lake fishes best low and quiet: float tubes over the weed channels, leeches and callibaetis under indicators, slow figure-eights with damsels in June. Wind builds by noon at 8,900 feet: mornings are the window, always.

Shallow soup, giant trout

Antero is a 20-foot-deep nutrient soup at 8,900 feet: scuds, damsels, and chironomids grow rainbows and cutthroat past 6 lb faster than any Colorado water. The technical game is float-tube stealth over the weed channels: stripping damsel nymphs in June, hanging chironomids under indicators the rest of the season. Periodic drain-and-refill cycles reset it: the years right after refill produce the giants.

Common questions

Why does Antero close sometimes?

Denver Water drains it periodically for storage and works: CPW then rebuilds the fishery, and the first years after refill produce the giants. Confirm current status: our page reflects conditions when open.

Why does Antero close periodically?

Denver Water drains it for dam work and drought storage cycles: each refill restarts the trophy clock. Review current status before driving South Park: when open, the first years are golden.
