The Winter "Chinook" Cure: How to Fish the Bow River in January (And Why You Should)

If you live in Calgary, you know the feeling. The temperature swings from a bone-chilling -20°C to a balmy +6°C in a matter of hours. That warm "Chinook" wind doesn't just melt the ice on your driveway; it wakes up the trout.

At Fly Fishing Bow River, we see January not as the off-season, but as the "technical season." The crowds are gone, the water is crystal clear, and the fish are holding in predictable winter runs.

If you are itching to get a bend in the rod before spring, here is what you need to know about fishing the Bow right now.

1. The Water is Low (and That’s a Good Thing)

Currently, the Bow is flowing at a winter baseline of roughly 30-40 cms (cubic meters per second). For the uninitiated, this means the river is "skinny."

• Where the fish are: Trout have moved out of the fast heavy riffles. They are stacking up in the slow, deep pools and "frog water" (water that looks almost still). They want to conserve energy.
• The Strategy: You don't need to cover miles of water. Find a deep bucket or a slow seam, and dissect it. If you catch one fish, don't move. There are likely twenty more sitting right next to it.

2. The Magic of the Midge

You might think dry fly fishing is months away, but you’d be wrong. On these warm January afternoons, we are seeing significant midge hatches.

When the air temp hits that 5°C mark, look for clusters of tiny insects on the surface. You'll see noses breaking the water in the soft slicks near the banks.

• The Rig: A Griffith’s Gnat (size #18-20) is your best friend here. If you can’t see it on the water, run it as a "dropper" behind a larger, more visible fly.
• Pro Tip: Winter fish are spooky. You need to downsize your tippet to 5X or even 6X fluorocarbon. If you are drag-free, they will eat.

3. Nymphing: Low and Slow

If the fish aren't looking up, you need to go down. Winter nymphing is a game of inches. The water is cold, so the trout are lethargic—they won't chase a fly. You have to hit them on the nose.

• The Flies: Red or pink San Juan Worms (the "Calgary staple"), small Zebra Midges, and Pheasant Tails with a bit of flash.
• The Depth: Set your indicator deep. If you aren't tapping the bottom occasionally, you aren't fishing.

Why You Should Book Your Summer Dates Now

While catching a 20-inch Brown Trout in a snowstorm is a badge of honor, it also reminds us of what’s coming: The Golden Stoneflies of July.

We are currently seeing a massive spike in bookings for the Summer 2026 season. Anglers who are out wading now are already locking in their float trips for the prime "Hopper" window.

Don't wait for the runoff. If you want to experience the Bow River at its absolute peak, you need to plan ahead.

Not All Hair is Created Equal: A Guide to Selecting Deer Hair for Fly Tying

If you’ve ever tried to spin a Muddler head using stiff bucktail, or tied a dry fly wing that flared out like a dandelion because you used belly hair, you know the struggle.

One of the most common questions we get at Thursday Night Live Fly Tying is: "Why does my deer hair look different than the tutorial?"

The answer is almost always the material itself. Deer hair is not a single product; it’s a spectrum. The texture, hollowness, and flare depend entirely on where the hair was harvested from the animal. To get your flies looking professional and fishing correctly, you need to match the hair to the application.

Here is your breakdown of the different types of deer hair for fly tying and how to choose the right patch for the job.

1. Bucktail: The Streamer Staple

Bucktail is likely the first hair most tiers buy. It comes from the tail of the deer and is distinct because it is solid (or semi-solid), long, and crinkly.

• Characteristics: It does not flare or spin well because the fibers are not hollow. It is durable and maintains its silhouette in the water.
• Best Uses: This is your go-to for streamers like Clouser Minnows and Lefty’s Deceivers. It provides the long, baitfish profile that predators love without the bulk of spun hair.

2. Deer Belly Hair: The Spinner’s Choice

If you want to tie big, buoyant bass bugs or dense heads, you need Deer Belly Hair. This hair comes from the underside of the whitetail deer. It is coarse, incredibly hollow, and typically white (which means it takes dyed colors vividly—think bright chartreuse or hot orange).

• Characteristics: Because it is so hollow, it crushes easily under thread tension, causing it to flare outward aggressively.
• Best Uses: Spinning hair for Bass Poppers, Divers, and large Muddler Minnows. If you are looking to pack hair tight for a "shaved" head, this is what you want.

3. Coastal Deer Hair (Comparadun Hair)

For the dry fly purist, this is the holy grail. Coastal deer (or specific patches labeled "Comparadun") have hair that is short, fine, and has short dark tips.

• Characteristics: It is less hollow than belly hair, meaning it won’t flare into a messy ball when you tie it in. It stays grouped together, creating a perfect upright fan.
• Best Uses: Comparaduns, Sparkle Duns, and wings for Humpies. If you are fishing the Bow River for picky rainbows, a sparse Comparadun tied with this fine hair is often the ticket.

4. Standard Body Hair: The Workhorse

This is often just labeled "Deer Hair" in shops. It comes from the flanks of the deer. It is a middle-ground material—it spins reasonably well but is finer than belly hair.

• Best Uses: Elk Hair Caddis variants (though Elk is stiffer), Stimulators, and smaller Muddler heads where you don't want the massive bulk of belly hair.

The Bottom Line

Don’t fight your materials. If you are struggling to get a fly to look right, check your package. You can't force bucktail to spin, and you can't force belly hair to make a neat dry fly wing.
