Delaware River Report: May 15, 2025

The release from Cannonsville is 600 cfs with 1,625 cfs spilling over the top. We had a little rain yesterday that didn’t do much to the flows. The East West, and Main flows all dropped a bit while the Beaverkill bumped slightly. There is still no wading on the main rivers but are in great shape for floating. The Beaverkill and Willowemoc have the only safe wading right now. Yesterday fished well with streamers and some dry fly shots in the afternoon. It’s a good mix of bugs with Hendricksons still holding on in some sections and a few sulphurs showing on other sections. Today looks similar with good cloud cover and less wind. The rain totals will be negligible.

Today will be 74 degrees, overcast with a slight chance of a rain shower. Total rainfall should only be .12″. Wind will be 5 – 10 mph from the South.
