Delaware River Report: August 3, 2026

The release from Cannonsville is 500 cfs. The rivers are up from last night’s rain. It looks like the flow at Hale Eddy peaked at 1,500 cfs. There is some color in the lower West that could make it a decent streamer morning. It should clear as it drops today. There’s no rain in today’s forecast so it should start to drop this morning. The flow in Stilesville bumped 10 cfs. The sulphur hatches have been decent 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.

Today will be 75 degrees and cloudy. Wind will be 10 – 15 from the West.
