Delaware River Report: September 28, 2025

The release from Cannonsville is 350 cfs. The release from Cannonsville will likely stay there until water is needed to meet the Montague Flow Target. Montague is at 2,250 and dropping this morning so hopefully they’ll call for additional water soon. We had a few more clouds than expected yesterday. Nymphing was still the best option but streamers are still in play – especially in low light. The rivers have cleared and dropped back. There are still small olives in the slow foam lines along with some Isonychias and Cahills towards dark. Definitely have your Isonychia spinners if you’re fishing late.

Today will be 81 degrees with partly cloudy skies. Wind will be 5 – 10 mph from the North.
