Delaware River Report: September 20, 2026

The release from Cannonsville is 475 cfs. We woke up to some light rain. Wunderground is calling for .1″ this morning but there is the possibility of a few heavier storms so keep any eye on the radar and click the gauge links below for the latest flow information. As of 6:30 am the rivers look good and the flows haven’t bumped yet. Nymphing worked well yesterday during the sunshine, 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 64 degrees with rain early. Wind will be 5 – 10 mph from the South.
