Delaware River Report: August 4, 2026

The release from Cannonsville is 500 cfs. The West Branch has dropped back and the clarity looks good this morning. The flow at Hale Eddy is 810 and dropping so we’re at a good level for floating and wading . The summer sulphurs are still hatching midday in Deposit. 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 82 degrees and partly cloudy. Wind will be light and variable.

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.
