Delaware River Report: August 25, 2026

The release from Cannonsville is 549 cfs. Wunderground is calling for clouds and a slight chance of some rain showers totalling .01″. So far it’s been sunny this morning. If the clouds roll in and we do get some light rain it could be a decent olive afternoon. There have been some flying ants most days bringing some fish to the surface. Some people have had some success blind casting Isonychias and Cahills. 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 72 degrees with clouds and a chance of rain showers. Wind will be 5 – 10 mph from the North.
