Delaware River Report: August 5, 2026

The release from Cannonsville is 500 cfs. The flows are still dropping so we’re at a good level for floating and wading. Today will look a lot like yesterday with a few more clouds so keep to the same plan. The summer sulphurs are still 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.

Today will be 83 degrees with cloudy skies. Wind will be 5 – 10 mph from the South.
