Delaware River Report: August 30, 2026

The release from Cannonsville is 500 cfs. We’ll have a few clouds this morning but should see more as the day goes on. If we do get a rainshower the total rainfall should only be .01″. The sulphurs are sporadic but people are finding them with fish eating. Olives and flying ants are putting some fish in the net along with blind casting 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 78 degrees with sun and clouds mixed early with increasing clouds in the afternoon. Wind will be 5 – 10 mph from the South.
