Delaware River Report: July 25, 2026

The release from Cannonsville is 500 cfs. We’re coming off another cool night but should warm up quickly this morning. The West Branch is at a good level for floating and wading. 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 82 degrees with abundant sunshine. Wind will be 5 – 10 mph from the South.
