Colorado Trout Fishing in The Spring

Trout Fishing in Colorado: A Springtime Adventure

Spring in Colorado is a magical time for trout fishing enthusiasts. As the snow melts and rivers swell with fresh runoff, filling lakes and reservoirs the state’s pristine waters come alive with trout eager to feed after a long winter. From the rushing streams of the Rockies to the tranquil reservoirs dotting the front range and plains, Colorado offers some of the best opportunities to catch trout in the country during the spring season. Whether you’re a seasoned angler or a beginner looking to cast a line, here’s what you need to know about trout fishing in Colorado in the spring.

The Trout of Colorado

Colorado is home to several trout species that thrive in its diverse waterways. The most common catches include rainbow trout, brown trout, and cutthroat trout—a native species—adding a special thrill for those fishing in higher elevations. In spring, these fish become more active as water temperatures rise and food sources like insects and small baitfish become abundant. The combination of hungry trout and dynamic water conditions makes March through May a prime time to hit the water.

Where to Fish

Colorado’s trout fishing spots are as varied as its landscape. Rivers like the Cache La Poudre River are renowned for their healthy trout populations and scenic beauty. In spring, these waters often run high and fast due to snowmelt, so anglers should be prepared for strong currents and shifting conditions. For a more relaxed experience, lakes and reservoirs such as Boyd lake, Carter Lake, Horsetooth Reservoir, Dowdy lake, Delaney Butte Lakes, and Lake John, Flatiron Reservoir, and Pinewood Reservoir offer excellent trout fishing from shoreline or boat. These still waters warm up faster than rivers, drawing trout closer to the surface as they chase bait. Tailwaters—sections of rivers below dams—are another spring hotspot. The consistent water releases from reservoirs like those on the Big Thompson River create stable conditions that trout love, even when other streams are swollen with runoff. These areas often yield impressive catches, especially early in the season.

Techniques and Tips

Spring trout fishing in Colorado calls for adaptability. With water levels fluctuating, anglers need to adjust their approach depending on the day. Using bait like worms and minnows can be highly effective, especially in murkier waters where trout rely on scent. Lures such as spinners, spoons, and small crankbaits also work well, mimicking the movement of prey and enticing strikes from aggressive fish. Timing is key in spring. Trout tend to feed most actively during mornings, and evenings during the warmer parts of the day, often mid-morning to late afternoon, as the sun heats the water. Overcast days can extend feeding windows, so don’t shy away from cloudy weather. Pay attention to water clarity, too—after heavy runoff, trout may hug the edges or seek slower pools where they can conserve energy while ambushing food.

Gear and Preparation

A light to medium-light action rod paired with 4- to 8-pound test line is a solid setup for most Colorado trout in spring. Bring a variety of tackle to match changing conditions, and don’t forget polarized sunglasses to cut glare and spot fish in shallow areas. Waders are useful for river fishing, as cold water and muddy banks are common this time of year. Check local regulations before heading out—Colorado enforces seasonal closures and catch limits to protect spawning fish, particularly in certain streams. Weather in spring can be unpredictable, with sunny mornings giving way to snow flurries by afternoon. Layered clothing, waterproof gear, and a thermos of hot coffee will keep you comfortable during long days on the water. Safety comes first: high flows can make wading tricky, so use a wading staff and fish with a buddy when possible.

The Spring Experience

Beyond the catch, trout fishing in Colorado during spring is about soaking in the season’s renewal. Snow-capped peaks loom over greening valleys, wildflowers peek through the grass, and the sound of rushing water fills the air. Wildlife is abundant—keep an eye out for deer, eagles, and even the occasional bear waking from hibernation. It’s a time when the state’s natural beauty is raw and untamed, offering anglers a front-row seat to the awakening of the wild.
