The Bow River remains open and fishable right now. Expect cold water temperatures, ice shelves along the banks, and limited insect activity. Fish are holding primarily in deeper, slower water and wintering pools. Anglrs have been having decent success, with the best success coming when presentations are slow and done with intent. Wading can be challenging due to ice and slush buildup, particularly in the later part of the mornings. Extra caution is advised near ice edges.
During this time of the year, trout metabolism is low in the cold water, so fish are conserving energy and feeding selectively. Most feeding occurs subsurface, with trout holding close to the bottom in softer currents. Dry fly eats are minimal, but the occasional midge activity may trigger sporadic rises during the warmest part of the day.
How to attack the river:
Nymphing (Most Productive):
Nymphing continues to be the most effective method this week.
Where to Focus:
- Deep runs and pools
- Slow seams and inside bends
- Tailouts below riffles
Patterns producing the most right now:
- Midge larva and pupa (sizes 16–22)
- Bloodworms
- San Juan Worms
- Small leeches
- Zebra midges and similar midge patterns
Both indicator nymphing and Euro nymphing setups are effective. Depth control is critical — don’t hesitate to add weight.
Streamer Fishing:
Streamers can produce fish, especially larger browns, when fished slow and deep. You can even try bottom bouncing a small leech. The slower the streamer moves the better really.
Dry Flies
Dry fly opportunities are limited but not impossible.
Best Bet:
- Small midge adults or emegers
It is essential to watch closely for subtle rises during midday, when temperatures typically peak.
Things to remember no matter the fishing technique:
- Use sink tips or heavily weighted flies
- Focus on deep bends, structure, and winter holding water
- Slow, deliberate retrieves are key
Winter fishing on the Bow River can be technical but rewarding. While peak dry-fly fishing typically occurs from mid-May through October, winter anglers who focus on subsurface techniques can still find consistent success.
Safety Considerations:
- Be cautious of ice shelves and unstable footing with higher than normal temperatures the ice can become very unpredictable.
- Dress appropriately for it may not be cold weather wise, but prolonged wading can wear on you.
