Delaware River Report: September 24, 2026

The release from Cannonsville is 475 cfs. We’re coming off another cold night and the water temps are in great shape. All of the rivers in the system look good. We’ll have some sunshine today so the best bets early will be nymphs or wet flies. We have had some odd midday olive hatches in the sun do keep an eye open in the slow foam. The West Branch has a greenish tint to it that is likely the reservoir turning. The fish and bugs don’t mind it and its actually better for streamer fishing. The West is at a good level for wading and floating. There have been tiny olives on some sections and a few Cahills, Isonychias, and hebes. The hatching should be less spotty as the flows drop and the nights get cooler. Streamers and nymphs are good bets early and late in the day.

Today will be 69 degrees and sunny. Wind will be 5 – 10 mph from the North.
