Delaware River Report: June 5, 2026

The release from Cannonsville is 500 cfs. It’s going to be another warm one with sun but we may see come clouds today. The weather has us in a bit of Summer mode right now. It’s worth looking for risers in the slow pools in the mornings eating left over spinners or caddis. Midday nymphing or blind casting the riffles are the best bets. We’ve had decent spinner falls and sulphurs in the evening once the sun drops. It still a mix of bugs with March Browns, Gray Fox, Cahills, Green Drakes, olives, and Sulphurs hatching.

The Mainstem in Callicoon and the East Branch in Hancock both peaked over 70 degrees yesterday. The Beaverkill at Cooks Falls peaked at 68 degrees. The water temps will peak higher today. It’s time to give these sections a break until we cool back down.

Today will be 87 degrees with sunshine and clouds mixed. Wind will be 5 – 10 mph from the North.
