Flow at Callicoon is running 3,930 cfs at 4.37 ft — significantly elevated from last week's 1,720 cfs, likely due to recent storm runoff — with water temperature at 65.3°F, right in the sweet spot for active trout feeding as the fall transition begins.

Best Time Window
- 6 AM - 9 AM: Pre-fog-burn streamer and heavy nymph time in the deep runs and pools — low light and high flows concentrate big fish in predictable lies.
- 10 AM - 2 PM: Prime BWO hatch window as fog clears and sun warms the water — watch the slower seams and eddies for rising fish and be ready to switch to dries.
- 5 PM - 7 PM: Evening caddis activity along the banks and tailouts — work the slower edge water with a CDC caddis pattern as light fades and terrestrial activity peaks.
Guide's Tip
From the benchWith flows nearly double last week's levels at 3,930 cfs, shift your focus away from the main channel and target the softer water — inside bends, current seams along the banks, and the slack water behind large boulders where trout are holding out of the heavy current. Use a longer, heavier indicator rig with at least 4-5 feet of depth and a heavy anchor fly to get your nymphs into the strike zone quickly. Morning fog will burn off by 9 AM, and the calm, sunny conditions that follow will set up a reliable BWO hatch from mid-morning through early afternoon — have a dry fly box ready and watch for subtle sipping rises in the slower edge water. As temperatures cool toward evening, switch to a streamer and swing the deep runs for the big browns that become aggressive predators in the fall transition.
