Delaware River Report: June 27, 2026

The release from Cannonsville is 500 cfs. We’ve got some clouds this morning and we’re hoping that they’ll stick around for the rest of the day. It was warm and humid yesterday but if the bugs were there midday in some sections and most everywhere in the evening. Bring all your summer favorites: sulphurs, Cahills, Isonychias, olives, and some caddis.

Today will be 79 degrees and cloudy. Wind will be light.
