Delaware River Report: September 22, 2026

The release from Cannonsville is 475 cfs. It’s beginning to look and feel like Fall. We have some colder nights coming that should help the water temps on the freestones and lower Mainstem. The river flows are dropping back to normal after the weekends rain and the clarity is decent. 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 65 degrees and generally cloudy. Wind will be light and variable.
