Before heading out, it helps to understand how winter conditions impact fishing.
“There’s no need to get out there too early,” says Troutfitter fly fishing guide Jon Carlton. “The warmest hours of the day are the best for fishing.”
In winter, trout primarily feed on small midges and mayflies, with hatches typically happening from mid-morning through mid-afternoon. If fish aren’t actively feeding, targeting deeper holes with streamers can be effective.
A well-stocked fly box for winter conditions should include zebra midges (sizes 18–23), blue-winged olives (sizes 18–22), woolly buggers, egg patterns, and attractor nymphs like pheasant tails, hare’s ears, copper johns, and prince nymphs.
Cold temperatures also require extra care when handling fish. If it’s below freezing, keeping fish in the water is critical to prevent gill damage. A good rule of thumb: if your line is freezing, conditions are harsh enough to require extra caution.
