Fishing Report: South Platte River at Waterton Canyon - 8.1.24

August Fishing Report: Waterton Canyon 

Current River Conditions

The South Platte River at Waterton Canyon is currently flowing at 258 CFS, providing excellent fishing conditions. Water temperatures range from the low 40s in the morning to mid-50s by the afternoon, due to controlled releases from Cheesman Reservoir​ (Colorado Division of Water Resources)​.

Despite some variability due to recent rain, the flows have been relatively stable, with Denver Water keeping flows between 600-700 CFS, though occasional spikes up to 900 CFS can occur. This fluctuation requires anglers to stay alert to weather forecasts and plan their trips accordingly​ (Waterton Canyon Report - July)​.

Hatches and Fly Patterns

Key hatches this time of year include midges, Blue Wing Olives (BWOs), caddisflies, and Pale Morning Duns (PMDs). Recommended fly patterns for successful fishing include:

• Nymphs: Foamback Emerger (sizes 20-22), Sparkle Pupa (size 16), Barr’s PMD Emerger (sizes 16-18).
• Dries: Mole Fly (size 22), Vis a Dun (size 20), Elk Hair Caddis (sizes 14-18).
• Streamers: Woolly Bugger (sizes 6-10), Sculpzilla (sizes 6-10).

These patterns effectively match the prevalent hatches and entice trout to bite​ (South Platte River)​.

Fishing Tactics

• Nymphing: Nymphing remains the most productive method. Adjust your depth and weight to match the current conditions and focus on seams, riffles, and runs where fish are likely feeding. Effective patterns include the Pheasant Tail, Hare's Ear, and Prince Nymph.
• Dry Fly Fishing: Dry fly fishing is also effective during hatches, particularly in slower seams and back eddies. Patterns such as the Blue Wing Olive and Pale Morning Dun can be very productive.
• Streamer Fishing: Use larger streamers to target big fish in deeper waters. Techniques such as dead drifting or stripping can be effective depending on the fish's behavior​ (Top Streamer Patterns)​​ (Brown Trout Fishing)​.

Safety Tips

Given the current flows and temperatures, wading can be hazardous. Always inform someone of your plans and avoid crossing the river at unsafe points. Use proper gear, such as a wading staff and boots, to maintain stability in the water. The swift currents can be dangerous, so exercise extreme caution​ (Rise Beyond Fly Fishing)​.
