Delaware River Report: August 2, 2026

The release from Cannonsville is 500 cfs. Today looks like a good day to be on the water. Cloud cover and some light showers in the afternoon. Total rainfall should only be .9″ during the day with another .34″ overnight. The wind will be a bit more than yesterday but seems manageable. 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 79 degrees with clouds in the morning and showers in the afternoon. Wind will be 10 – 15 from the South.
