South Platte River Fishing Report – Waterton Canyon – January 2024
Waterton Canyon remains a winter wonderland for anglers seeking solitude and the thrill of a challenge. The canyon's picturesque landscape, with snow-dusted cliffs and the soothing sound of flowing water, creates the perfect setting for a peaceful day on the river. While trout are holding in deeper runs and slower pools, they’re still eager to take a well-presented nymph or midge, rewarding patience and precision.
The lower flows and colder water mean stealth and strategy are your best allies. With few anglers on the water, it's an excellent time to explore less-pressured stretches of the canyon and refine your winter fishing techniques. Dress warm, wade carefully, and enjoy the serenity of Waterton Canyon in its off-season glory.

Tips Fly Fishing on Waterton Canyon
Seasonal Tip
Focus on the warmest part of the day, and target deeper runs where trout are conserving energy. Use a stealthy approach to avoid spooking them in low flows.
Dry Fly
Dry fly opportunities are rare but possible on sunny days when midges are hatching.
Nymphing
A two-fly nymph rig with a Mercury Midge and a small Baetis pattern is your best bet for consistent action.
Streamer Fishing
Slow, deliberate strips with smaller streamers can provoke strikes from larger trout.
