Delaware River Report: July 19, 2026

The release from Cannonsville is 500 cfs. We were hit with some hard storms last evening. Some of the secondary roads may have trees down. The main roads seem fine this morning. Some areas don’t have power. The rivers look totally fine. The West Branch has a little color that may actually be a bonus for the fishing today. Sulphurs, Cahills, Isonychias, olives, and some caddis are all hatching in some numbers. The daytime sulphurs are hatching in Deposit mixed with some olives and a few Isonychias. 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 74 degrees and partly cloudy. Wind will be 10 – 15 mph from the North.

Dark Blue Wing Olive – #16 – 18 – Baetis vagans
Sulphur – 16 – 20 – Ephemerella dorothea
