Delaware River Report: June 25, 2026

The release from Cannonsville is 500 cfs. We’re starting off the day with some clouds and cooler air temps. The hatches have been a mix of sulphurs, Cahills, Isonychias, olives, and some caddis. Look for sulphurs in the middle of the day and spinners in the evening. If we get some light rain this evening, have your small olive patterns with you.

Today will be 77 degrees and cloudy with a chance of showers later in the day. Wind will be 5 – 10 mph from the South.
