Delaware River Report: July 22, 2026

The release from Cannonsville is 500 cfs. Most of yesterday’s storms slid around us. The West Branch is up slightly but is already dropping back to normal. We’re clear and at a good level for floating and wading. The Beaverkill and lower East Branch got more rain and are up quite a bit from yesterday. 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 74 degrees and mostly cloudy. Wind will be 10 – 15 mph from the North.



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
