Delaware River Report: August 22, 2026

The release from Cannonsville is 549 cfs. There’s some dense fog this morning that should burn off in the next hour or so. Then we’ll have some sunshine again. There was some mid morning dry fly action in the sun so keep a rod ready early just in case. Some people have had some success blind casting Isonychias and Cahills too. The mid day sulphurs are getting a bit spotty as the hatch wanes but there still are some out there. 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 78 degrees and partly cloudy. Wind will be 5 – 10 mph from the South.
