Trout do not stop eating in winter, they just slow way down, and so must you. Cold water drops a trout's metabolism, so the fish hold in the slowest, deepest water and eat small, easy meals with as little effort as possible. Match that reality, fish slow and deep with tiny flies, and winter can be some of the most peaceful, productive fishing of the year.
Where the fish are
Forget the fast riffles. In winter, trout stack in the slowest, deepest holding water, deep pools, the soft inside of runs, and the seams alongside slow current, where they can hold with minimal effort. Tailwaters (rivers below dams) stay warmer and more stable and are the winter trout angler's best friend.
How to fish it
- Go small and deep. Winter trout key on midges and small nymphs, often tiny. Get them down to the fish with split shot or a heavy point fly, they will not move far or fast to chase.
- Slow everything down. Dead-drift your flies right along the bottom through the slow water. Contact/euro nymphing, see euro nymphing, is ideal for detecting the ultra-soft winter takes.
- Fish the warm window. The bite is often best in the warmest part of the day, late morning through mid-afternoon, when a few degrees of warming nudges fish and insects to move.
Tip Watch for tiny winter midge hatches on soft, sunny afternoons, you may find trout sipping in the slow tailouts. A small dry or emerger to a rising winter fish is an unexpected treat.
Stay safe and comfortable
Cold water is serious. Dress in warm layers, wear felt or studded boots for icy footing, and never wade beyond your ability in cold, high water. Keep your guides clear of ice, bring hand warmers, and know that hypothermia is a real risk, fish with a buddy when you can, and get off the water if you get too cold.
Gear
A standard 5-weight outfit works fine; the changes are in the flies (small) and the presentation (slow and deep). Add split shot to get down, use a fine tippet for the tiny flies, and keep a rag handy to clear ice from your guides.
