Delaware River Report: July 28, 2026

The release from Cannonsville is 500 cfs. We have some showers passing through this morning with more on the way. We could see an inch of rain with another half inch overnight. The West Branch has bumped up slightly as of 7 am. If the flows change dramatically during the day we;ll do an update but for the most up to date flows click on the gauge links below. 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 72 degrees with rain. Wind will be 10 – 15 from the South.
