Tactics & Tips

Morning: Focus on indicator nymphing with midges and Baetis nymphs in riffles and deeper runs.
Afternoon: Dry fly fishing with Parachute Adams and BWO emergers along seams and foam lines.
Evening: Watch for midge and Baetis activity near shore; try small midges on fine tippets.
Streamer Fishing: Aggressive fishing with Sculpzilla or Baby Gonga in deeper pools and near structure can trigger strikes.

Use 6X or finer tippet for midges; stealth approach is critical due to clear water and low flows.
