Delaware River Report: September 11, 2026

The release from Cannonsville is 475 cfs. Today is going to be bright and sunny. We’ve seen some tiny olives in the afternoon on some sunny days so keep an eye out in the slower foam lines. 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 72 degrees with abundant sunshine. Wind will be 5 – 10 mph from the North.
