Delaware River Report: May 19, 2025

The release from Cannonsville is 600 cfs with 588 cfs spilling over the top. We had a few showers again yesterday and overnight but not enough to bump the flows. The rivers are still dropping and we are seeing some wading on the West Branch. The Beaverkill and Willowemoc are at great levels for wading. Streamers and nymphs have accounted for a lot of fish over the last few days but there are march browns, gray fox, sulphurs, and tan caddis around. The cahills should be around soon too.

Today will be 60 degrees with clouds in the morning giving way to sunshine in the afternoon. Wind will be 10 – 20 mph from the North.
