Delaware River Report: July 26, 2026

The release from Cannonsville is 500 cfs. We already have a few more clouds showing than yesterday morning. Hopefully we keep them. There is a chance of some scattered afternoon thunderstorms so bring a rain jacket just in case. The West Branch is at a good level for floating and wading. The daytime sulphurs are hatching in Deposit mixed with some olives and a few Isonychias. Smaller seems to be better. Stick to the lower West if you want to nymph. The algae has been bad up top making it a dry fly only game.

Today will be 80 degrees and partly cloudy. Wind will be light and variable.
