Delaware River Report: September 1, 2026

The release from Cannonsville has been cut back to 450 cfs. We had a few storms pss through overnight so the feeder streams are adding some additional water. So far everything looks good this morning. We have the possibility of 1 – 2″ of rain today depending on how the storms track. If anything changes dramatically we’ll post an update. click on the gauge links below for the latest flow information. And keep an eye on the radar. The last of the sulphurs in Deposit have been sporadic and unpredictable but some people have been finding a few fish on them. There are a few Isonychias and Cahills in the evening along with some hebes. The ants have been around – not in big numbers but they’re here. Stick to the lower West if you want to nymph. The algae has been bad up top making it a dry fly only game.

Today will be 75 degrees with thunderstorms and rain. Total rainfall should be 1.21″. Wind will be 5-10 mph from the West.
