Delaware River Report: June 2, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is 828 cfs spilling. We’re good levels for floating but there is no safe wading on the main rivers today. The Beaverkill is dropping nicely and should offer some wade spots in the next day or two. The West Branch is in good shape this morning with good visibility. Fish were eating yesterday. We have a mix of March Browns, Gray Fox, Sulphurs, Isonychias, Light Cahills, and some Green Drakes on the water. Streamers are working well in the mornings before the hatches. We’ll have more sun today but less wind.

Today will be 70 degrees with a mix of clouds and sun. Wind will be 5 – 10 mph from the North.
