Delaware River Report: August 10, 2026

The release from Cannonsville is 500 cfs. The weather and fishing hasn’t changed much since the last big rain. Hot with a chance of afternoon thunderstorms. We should see some showers today with total rainfall around .14″. There is a chance of some thunderstorms so keep an eye on the radar and check the gauge links below for the latest flows. The fishing on the WB has stayed relatively consistent with the summer sulphurs hatching midday in Deposit. 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.
