Delaware River Report: September 3, 2026

The release from Cannonsville is 450 cfs. We were hit by some thunderstorms last night and all of the rivers are high and off color. The West Branch at Hale Eddy is 1,240 cfs and still climbing at 6:30 am. Oquaga Creek has peaked at 224 cfs and is beginning to drop. The rest of the feeders should follow suit this morning. The flow at Stilvesville hasn’t budged so if you fish near the gauge it will be wadeable and clearer.

Today will be 81 degrees with scattered thunderstorms in the afternoon. Total rainfall during the day should be .01″. Wind will be 5-10 mph from the West.
