Delaware River Report: September 17, 2026

The release from Cannonsville is 475 cfs. Today looks like a good day to be on the water with rain early, clouds, and maybe some afternoon showers. Total rainfall should be less than 1/4″ today. So it definitely looks like an olive day. Streamers could be a good bet with the rain and the color of the West Branch. 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 76 degrees with rain early. Total rainfall should be .17. Wind will be light and variable.
