Delaware River Report: August 26, 2026

The release from Cannonsville is 549 cfs. We’ll have some sun today but no wind. It’ll be a little bit warmer but the nighttime air temps are still cool. Olives and flying ants are putting some fish in the net along with blind casting Isonychias and Cahills. The mid day sulphurs are getting a bit spotty as the hatch wanes but there still are some out there. There are some olives mixed in plus a few Isonychias and Cahills. 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 79 degrees with a mix of clouds and sun. Wind will be light and variable.
