Today's Fishing Report

Generated this morning from live readings: gauge, weather model, sun and moon. A fresh report is published here every morning.

2/5Slow. The wind owns today.28 mph gusts make boat control the real battle.

Antero Reservoir fishes cold and honest: earn your bites in the deep stuff. Today brings clear skies, wind SSW around 20 mph, falling pressure near 1010 hPa and a high of 56. Water sits around 47 F for the season (estimated). With the waxing gibbous, the solunar majors run 9:41 AM-11:41 AM and 10:10 PM-12:10 AM: the windows to build the day around.

The plan, species by species

Rainbow troutExcellent

In cold water rainbows use the deepest pools in rivers (Vermont), so slow, deep drifts there are the usual approach; Michigan DNR notes lake rainbows are also taken with bait or by jigging through the ice.

Brown troutExcellent

Below 50Β°F, fish slowly through the deeper pools; in early spring on the Great Lakes, Michigan DNR notes browns are often caught inshore before other species start biting.

Tomorrow: Cooler at 35 F with likely rain: fish ahead of the front. The solunar majors shift about 50 minutes later.Next report: Sat, Oct 24, 6:30 AMHow this report is made β†’

Rainbow trout illustration

Rainbow trout

Spring and fall in most lakes; rivers fish year-round while the water stays cool

A cold-water trout native to Pacific drainages from Alaska to Baja California, now stocked in most states and fished in rivers, tailwaters and lakes. In cold water rainbows use the deepest pools in rivers (Vermont), so slow, deep drifts there are the usual approach; Michigan DNR notes lake rainbows are also taken with bait or by jigging through the ice.

Brown trout illustration

Brown trout

Spring along Great Lakes shorelines; low light and overcast days in rivers; fall spawning runs

A European trout first stocked in the US in 1883 and now fished in rivers and lakes nationwide; it tolerates warmer water than other trout, and mature stream fish feed mostly at night. Below 50Β°F, fish slowly through the deeper pools; in early spring on the Great Lakes, Michigan DNR notes browns are often caught inshore before other species start biting.

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.

The written guide on this page
Pablo Ruiz Quintero
How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written guide was drafted with AI assistance. Unlike our newer pages, it does not yet list the official pages its facts were checked against: that audit is under way, and anything it cannot verify will be taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Errors are published in the verification log; the full policy is in the editorial policy.

Readings refresh on a 30-minute window. The full method, with every figure and its source, is on how our reports are made. Something wrong here? Tell us and it goes in the log with the date.
