Delaware River Report: September 12, 2026

The release from Cannonsville is 475 cfs. We have a bit of fog this morning but that will burn off quickly. It should get cloudier as the day progresses. Hopefully that pushes some tiny olives midday. Nymphs, streamers, and wets may be the better bet until the sun starts to drop in the evening. Blind casting Isonychias and Cahills could pay off. That’s been more day to day. 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

Today will be 78 degrees and partly cloudy. Wind will be 5 – 10 mph from the South.
