Delaware River Report: August 1, 2026

The release from Cannonsville is 500 cfs. We’ll see some sun in the morning but if Wunderground is correct we should have overcast skies by the afternoon. The fishing on the West Branch will be the same as it’s been for a few weeks. 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 84 degrees and partly cloudy in the morning. Wind will be 5 – 10 from the South.



What’s Hatching:
Dark Blue Wing Olive – #16 – 18 – Baetis vagans
Sulphur – 16 – 20 – Ephemerella dorothea
Tan Caddis – #16 – 20 – Hydrosyche sp
Light Cahill – #14 – Epeorus vitreus, Ephemerella invaria, Stenacron spp.
Slate Drake – #12-2xl – 12 – Isonychia bicolor
