San Juan River February 2026

February on the San Juan is doing what February does best: it’s fishing well—if you’re willing to fish the conditions instead of wishing them away.

The biggest storyline right now is water clarity. With repairs underway on the main release gate, they’ve been running water through the 4×4 auxiliary gate, and it’s pushed a little extra color into the river. It’s not chocolate milk, but it’s definitely stained enough that the river isn’t setting up for consistent surface feeding… yet.

Flows are sitting right around 300 CFS, and despite the dirty water, the trout have been plenty willing to eat. You just have to meet them where they are.

What the River Is Asking For Right Now

In February, especially with stained water, we’re keeping it simple: heavy nymph rigs and clean drifts in the lower third of the water column. If you’re ticking bottom occasionally and you’re not hanging up every other cast, you’re usually in the right neighborhood.

The takes can still be subtle, so a good indicator setup and paying attention to micro-pauses matters. This isn’t the month for lazy drifts and daydreaming—February rewards the anglers who stay engaged.

What’s Working (And What’s Staying Tied On)

Our rigs haven’t changed much because the fish haven’t asked us to change them. These patterns have been steady producers day after day:

• Mops
• Worms
• Red larva
• Jig leeches in white and black
• Egg patterns

If you’re running two flies, think in terms of “show them something obvious” plus “give them something natural.” A worm or mop paired with a red larva, egg, or small leech has been a solid formula in this off-color water.

Bug Activity Is There… The Rising Just Isn’t (Yet)

We’ve seen a surprising amount of bug activity for February, which is a good sign heading into spring. But with the current clarity, we haven’t seen much consistent rising. That doesn’t mean the river is dead up top—it just means the fish are feeding with more confidence subsurface, where visibility and opportunity are better.

Translation: if you’re trying to force dry flies right now, you’re probably leaving fish on the table.

Streamers Eaters Are Waking Up

Even in February, we’re starting to see the early signs that trout are “switching on” to streamers again. The first truly consistent streamer window on the San Juan is usually right around the corner in March, and we’re close.

When that bite turns on, it’s one of the most fun times of the year: aggressive eats, better shots at bigger fish, and a totally different pace than the nymph grind. If you’re a streamer person, keep your eye on March—this is when it starts getting interesting.

Looking Ahead: Spring

Between the bug activity we’re already seeing and the seasonal shift that’s coming, we’re expecting some solid dry fly fishing this spring. Once the water cleans up and stabilizes, those surface opportunities tend to show up in a real way—and spring on the San Juan can be excellent for anglers who want to mix it up: nymphs in the morning, possible dries during the right windows, and streamers when conditions line up.

Spring Trips — If You’re Thinking About It, Don’t Wait

Spring is one of our favorite windows on the San Juan. The weather is better, the river starts to feel more alive, and you get more variety day to day. If you’re looking to get a date on the calendar—especially for March and April—now is the time. Our Spring dates are filling fast.

If you want to fish the San Juan while it’s waking up and before the season really stacks up, reach out and we’ll get you lined up with the right trip for your goals.

See you on the water,
