Delaware River Report: September 16, 2026

The release from Cannonsville is 475 cfs. The river flows have dropped and are a bit more normal this morning. We’ve had a few showers this morning but the amount of rain has been negligible. 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 78 degrees with overcast skies. Wind will be light and variable.
