Delaware River Report: September 15, 2026

The release from Cannonsville is 475 cfs. The river flows have dropped a bit as the runoff subsides. They should be clearer today too. The West Branch 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. 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 71 degrees with a mix of sunshine and clouds. Wind will be 5 – 10 mph from the South.
