Waterton Canyon on the South Platte River isn’t just another spot on the map—it’s a rite of passage for fly fishing enthusiasts. If you’re looking to sharpen your skills, this is the place. The canyon’s reputation as one of the most technical fisheries around isn’t just for show; it’s earned. The fish here are seasoned opponents, often called “spooky,” requiring precision in every cast. With its clear waters and complex currents shaped by large granite boulders, the river demands your full attention and best technique.

South Platte River Fishing Report – Waterton Canyon – December 2024
Waterton Canyon offers a serene and accessible winter fishing destination just outside Denver. With flows steady at 40-60 CFS, the water is low and clear, requiring technical precision and stealth to fool the canyon’s wily trout. Trout are concentrated in deeper runs and slower pools, feeding on midges and the occasional Blue Wing Olive during warm afternoons. The dramatic canyon scenery, paired with minimal crowds, makes this stretch a winter gem for patient anglers.
Late morning to early afternoon is the sweet spot, as the sun warms the water and trout activity increases. Nymphing remains the most consistent tactic, though dry fly opportunities arise during sporadic midge hatches. For those targeting larger trout, streamers fished slowly along structure may provoke a strike. Dress warmly and prepare for a peaceful, scenic day on the water. We might skip this spot for a while. A long while. At least until the pressure of other anglers subsides or the bit and waters heat up.

Tips Fly Fishing on the Waterton Canyon Section
Seasonal Tip
Low flows and cold water demand patience and stealth. Approach pools carefully, use long leaders, and focus on deeper holding water.
Dry Fly
Sporadic midge hatches offer surface action on sunny days. Target risers in calm eddies and tailouts with small, delicate patterns.
Nymphing
A double-nymph rig featuring a Zebra Midge and Black Beauty is your go-to setup. Add enough weight to get your flies down to feeding fish in deeper runs.
Streamer Fishing
Streamers like Olive Woolly Buggers or small sculpin patterns can coax larger trout from structure. Use slow, deliberate retrieves.
