Delaware River Report: September 9, 2026

The release from Cannonsville is 475 cfs. Today looks like a good day with cloud cover and a chance of a shower or thunderstorm. Wind doesn’t look bad. Hopefully we get some precip and it pushes the bugs a little earlier in the day. 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. Nymphs and wets have been putting some fish in the net too.

Today will be 79 degrees with clouds. There is a chance of a passing shower or thunderstorm. Wind will be 5 – 10 mph from the South.
