Delaware River Report: June 10, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is 1,594 cfs spilling. The West Branch flow dropped slightly. We’ll have to watch how today’s storms track. The rivers are in decent shape. The spill is still keeping Stilesville warm the river cools down by Hale Eddy. The best wading is still on the Beaverkill and Willowemoc. The hatches have still been later due to the warmer water temps. Along with sulphurs and cahills definitely have your Isonychia box this week. Streamers and nymphs have worked well early.

Today will be 76 degrees with rain and thunderstorms. Total rainfall should be .36″. Wind will be 5 – 10 mph from the South.
