Red Quills should appear with cooler morning temperatures; also Baetis, Tricos, flying ants, caddis, and small crane flies depending on location and timing
Conditions
The Big Wood is running low and clear through mid-September, demanding a careful approach and precise casts. Fish are eager on the first presentation but rarely take a second look, so stealth and accuracy are essential. Cool mornings will bring Red Quill activity, while Baetis, Tricos, flying ants, and small crane flies work depending on location and time of day. Flows are expected to continue falling through the forecast window.
