Delaware River Report: May 21, 2026

The release from Cannonsville is 425 cfs. We had some spotty rain in some areas yesterday but not enough to affect the rivers. Today will be overcast and much cooler. It looks like a good day to be on the water. Caddis are still around in good numbers getting some fish looking up midday. The caddis have really been everywhere, Hendricksons are still hanging on in some river sections with March Browns, Gray Fox, and olives mixed on other sections. Definitely have your sulphur box just in case.

Today will be 61 degrees with cloudy skies. Wind will be 5 – 10 mph from the North.
