South Platte River Fishing Report – Waterton Canyon – January 2024
Waterton Canyon is winter’s hidden gem for fly fishing enthusiasts. Nestled just a short drive from Denver, this stretch of the South Platte River offers a unique blend of accessibility and tranquility. As the temperature drops, the crowds thin out, leaving you with a serene fishing experience and a healthy population of eager trout. The canyon’s towering walls and crystal-clear water make for postcard-perfect winter days.
Trout here are feeding steadily during mid-day windows, particularly on small nymphs and midges. While dry fly action is rare this time of year, don’t overlook a well-presented emerger pattern. The cold water keeps fish concentrated in deeper pools, so focus your efforts there. Remember, layers are your friend—both for your rig and your wardrobe!

Tips Fly Fishing in Waterton Canyon
Seasonal Tip
Winter in Waterton is all about finding the right rhythm. Fish are less active in the early morning but will pick up by late morning when the sun warms the water slightly.
Dry Fly
Rare but possible—watch for subtle rises near eddies or slower pools on warmer afternoons. A small Griffith’s Gnat is your best bet.
Nymphing
Focus on slower, deeper runs with a double nymph rig. Pair a Zebra Midge with a small Blue Wing Olive nymph for an effective combination.
Streamer Fishing
Use smaller streamers and slower retrieves to coax strikes from trout holding in deeper water.
