Delaware River Report: September 11, 2025

The release from Cannonsville is 594 cfs. We’re still in great shape for wading or floating. Conditions should be about the same as yesterday with a litte more wind. Nymphing or swinging wets will be the best bets during the day. If you’re looking for dry fly fishing early blind casting Isonychias or Cahills in riffles could pay off. In he afternoon we’ve been seeing good olive hatches along with hebes. We haven’t seen huge flying ant falls (likely due to the weather) but there are out there.

Today will be 76 degrees and sunny to partly cloudy. Wind will be 5 – 10 ,ph from the North.


Sadly Ryan Geiges, a friend and former DRC guide, recently lost his battle with cancer. He will be missed by many – both off and on the water. There is a GoFundMe for Ryan’s family if you’d like to support them in this difficult time.
