Antero Reservoir Fishing Trips – Trophy Trout & Ice Fishing in South Park, Colorado

Antero Reservoir is one of Colorado’s most fertile and productive trout fisheries. Known for fast-growing fish and frequent action, this shallow, nutrient-rich lake in the South Park basin offers excellent ice fishing and early-season boat fishing for anglers of all experience levels.

With a short drive from the Front Range, Antero is the perfect choice for a full day of trophy trout fishing in a scenic high-mountain setting.

What Can You Catch at Antero Reservoir?

Antero supports a variety of trout and hybrid species, many of which grow to trophy size thanks to abundant weed beds and a huge scud population (freshwater shrimp). It’s one of the few lakes in Colorado where multiple trout species thrive side by side.

Species Include:

  • Rainbow Trout

  • Brown Trout

  • Cutbows (Rainbow x Cutthroat)

  • Snake River Cutthroat

  • Greenback Cutthroat

  • Brook Trout

  • Splake (Brook x Lake Trout hybrid)

  • Kokanee Salmon (occasionally)

Trout average around 15″, with many pushing 18″+ and trophy fish exceeding 20″ caught regularly. The shallow waters and rich ecosystem lead to fast growth and aggressive feeding behavior.

Ice Fishing on Antero Reservoir

Winter fishing is a favorite here, especially with the lake’s extensive weed beds. These areas become ambush points for feeding trout and make for exciting and productive ice trips.

Ice Fishing Season:

  • Mid-December through early March

We provide heated shelters, sonar, high-quality rods, and bait to keep you comfortable and successful on the ice. It’s an excellent option for families, beginners, or anyone looking for consistent trout action in a peaceful winter setting.

Open Water Trips – Early & Late Season Tactics

Due to shallow depths and midsummer weed growth, trolling can be tricky in summer—but with the right approach, big fish are still within reach.

Best Boat Fishing Windows:

  • Ice-off to early June

  • Late August to closing

During these times, we offer guided trolling and casting trips focused on rainbow trout, brown trout, and hybrid species. Our guides know how to adapt to the lake’s conditions and help you find success even when others struggle.
