Delaware River Report: September 28, 2026

The release from Cannonsville is 475 cfs. The rivers came through the storm in great shape with just a negligible bump in flows this morning. We’re still in good shape for floating and wading. Today’s clouds are just an added bonus. Small olives have made up most of the hatch but there are some Cahills, hebes, and sporadic Isonychias out there. We’ve seen more Isonychia spinners than duns in the last week. The West Branch has a greenish tint to it that is likely the reservoir turning. The fish and bugs don’t mind it and its actually better for streamer fishing.

Today will be 60 degrees with clouds and morning rain showers. Total rainfall should be .17″. Wind will be 5 – 10 mph from the North.
