Delaware River Report: May 12, 2026

The realease from Cannonsville is 902 cfs with 189 cfs spilling. The rivers are still. The best wading is still on the Upper East Branch, and Willowemoc. The Beaverkill dropped below 1,000 cfs so there are more wade opportunities there today. We had decent Hendrickson hatches on some sections along with caddis and Hendrickson spiinners. Hendricksons, Dark Brachycentrus, Gray Fox, and March Browns are mixed a bit on some river sections. The colder water sections may still see some blue quills. Today looks like another day of lesser wind.

Today will be 62 degrees and mostly sunny. Wind will be 5 – 10 mph from the North.
