Delaware River Report: July 27, 2026

The release from Cannonsville is 500 cfs. The forecast keeps changing but as of 7 am we should see a few showers this morning with .1″ of rainfall. We may see some afternoon thunderstorms but it looks like most of the rain has been pushed off to tomorrow. The forecast will likely keep changing so keep an eye on the radar this afternoon. 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 82 degrees with showers early anc a chance of afternoon thunderstorms. Wind will be light and variable.
