Delaware River Report: September 26, 2026

The release from Cannonsville is 475 cfs. It looks like we’re just catching the edge of the storm with just a little rain today and the same wind as yesterday. The clouds will be a bonus. Nymphs and streamers could be good bets in today’s weather. Small olive have made up most of the hatch but there are some Cahills 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 61 degrees overcast with periods of rain showers. Total rainfall should be .15″. Wind will be 10 – 20 mph from the North.
