Delaware River Report: July 16, 2026

The release from Cannonsville is 500 cfs. It’s going to be cooler today only hitting 84 degrees. The smoke / haze is back giving the sky an odd glow and blocking a lot of the sunshine. You can smell the smoke at times. Sulphurs, Cahills, Isonychias, olives, and some caddis are all out on the water. There are some tiny olives mixed with the sulphurs in Deposit so keep an eye out for those. Stick to the lower West if you want to nymph. The algae has been bad up top making it a dry fly game.

Today will be 84 degrees with some clouds early and clearing a bit in the afternoon. Wind will be 10 – 20 mph from the North.
