Delaware River Report: June 4, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is just under 800 cfs spilling. The Beaverkill has dropped quite a bit so there are lots of wade opportunities there and on the Willowemoc. The tailwaters and Mainstem are dropping slowly and still best fished from a boat. The sun may push the hatches a little later in the afternoon but it may also get some caddis active early in the day. If the caddis stay on the bushes nymphs and streamers should work well until the bugs come. It’s till a big mix of bug hatching so carry a lot of flies. And keep an eye out for spinners in the evening.

Today will be 86 degrees with sun. Wind will be 5 – 10 mph from the South.
