Delaware River Report: June 12, 2026

The release from Cannonsville is 500 cfs. We had a few storms push through last night. The river flows bumped slightly but not enough to really matter. The river flows are already dropping back. We may see a few more storms today so keep an eye on the radar. Wonderground is putting the total rainfall around .3″. Cahills, olives, and caddis are all around in some numbers. The sulphurs have been decent on some river sections in the evening. The cloud cover and rain (if we get it) could push some of the hatches earlier.

The Mainstem, the East Branch in Hancock, and the Beaverkill at Cooks Falls all peaked at or over 70 degrees again yesterday. It’s time to give these river sections a break until we cool back down.

Today will be 87 degrees with potential scattered thunderstormsstorms. Wind will be 5 – 10 mph from the North.
