Best Time of Year to Fish in Colorado: Seasonal Fishing Guide

What is the Best Time of Year to Fish in Colorado?

Ah, Colorado—the land of towering peaks, endless blue skies, and some of the finest fishing this side of paradise. But here’s the deal: timing is everything. Cast your line at the wrong time, and you might as well be fishing for compliments. Nail the right season, though, and you’ll be reeling in fish faster than you can say, “Pass the net!” So, when is the best time to fish in Colorado? Let’s break it down, season by season, with a splash of wit to keep things interesting.

Spring (March to May): Fish Waking Up, Just Like You Before Coffee

Spring is nature’s alarm clock, and Colorado’s fish are hitting snooze... until they’re not.

• What’s Happening? Rivers swell with snowmelt, turning once-polite streams into raging waters. It’s messy, but the fish don’t care—they’re starving.
• Who’s Biting? Rainbow trout are the main act, out and about for their spawning season. Pike and bass start flexing in the shallows, too.
• How to Win: Toss a nymph or streamer their way and watch the magic happen. If it doesn’t, blame the current—it’s not you.

Wisdom: Stick to tailwaters, where the rivers behave like they’ve had their morning yoga session—calm, clear, and steady.

Summer (June to August): Fishing’s Red Carpet Season

Summer in Colorado is a literal cast party, and every angler is invited. Grab your gear and your best excuses for skipping work.

• What’s Happening? Snowmelt has finally chilled out, leaving rivers sparkling like a Pinterest dream. The weather? Chef’s kiss.
• Who’s Biting? Trout galore—brown, cutthroat, brook. Kokanee salmon might even RSVP. High-altitude lakes are the VIP section.
• How to Win: Dry flies are your BFF this season. Match the hatch (think caddisflies and mayflies), and you’ll be everyone’s favorite angler.

Wisdom: High-country lakes are the ultimate summer getaway for trout... and for you, if you need a break from the heat and humanity.

Fall (September to November): Big Fish Energy

Fall in Colorado is like a Taylor Swift album—bold, dramatic, and oh-so-good for reeling in heartbreakers (aka trophy fish).

• What’s Happening? Cooler temps mean calmer waters and fish gearing up for winter. The crowds? Gone. It’s just you and the scenery.
• Who’s Biting? Brown trout are in full pre-spawn mode, and they’re hangry. Kokanee salmon are running, which is as wild as it sounds.
• How to Win: Streamers are the pumpkin spice of fall fishing—irresistible to fish with an attitude.

Witty Wisdom: Hit the Gunnison or Taylor Rivers for brown trout so big, they’ll have you bragging at every holiday party.

Winter (December to February): Ice, Ice, Baby

Winter fishing in Colorado isn’t for the faint of heart—or thin of socks. But if you’re brave enough, the rewards are worth the frostbite risk.

• What’s Happening? Streams freeze, snow piles up, and ice fishing takes the spotlight. You’ll have the place to yourself because, let’s face it, most folks are inside with hot cocoa.
• Who’s Biting? Rainbow and brown trout in tailwaters are still game. Ice anglers can land lake trout, walleye, and perch in frozen reservoirs.
• How to Win: Dead-drift a midge in tailwaters or jig your way to glory on the ice. Bonus points if you stay warm.

Wisdom: Dress like you’re auditioning for a polar expedition. And remember, the Arkansas River below Pueblo Dam is a year-round hero thanks to its warm water flows.

Final Thoughts

Colorado’s fishing seasons are as dynamic as its weather (read: unpredictable but always thrilling). Whether you’re chasing the perfect summer dry fly hatch, fall’s big brown trout, or winter solitude, there’s a time and place for every angler. Just remember: no matter the season, you’re in Colorado. Even if the fish don’t bite, the views are worth the trip.

So pack your tackle, bring your A-game, and don’t forget to practice your “big one got away” story. Tight lines, folks!
