Delaware River Report: September 8, 2026

The release from Cannonsville is 475 cfs. The mornings have been chilly and it feels like Fall is coming. That should be good for the river system. We’ll have some sunshine today but should get some clouds back tomorrow. Olives and flying ants are still the main bugs but there are some Isonychias, Cahills, and hebes around. Blind casting the larger bugs in the riffles can pay off. We’re dealing with bright sun today so streamers will work best before the sun hits the water or after it drops this evening. Nymphs and wets have been putting some fish in the net too.

Today will be 78 degrees and mostly sunny. Wind will be light and variable.
