Delaware River Report: June 9, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is over 1,300 cfs spilling. The West Branch flow has leveled off. The rest of the rivers are dropping slowly. We’re at fine levels for floating but the best and safest wading is on the Beaverkill and Willowemoc. The highest water temp is actually in Stilesville due to the spillage. Hopefully the cooler air temps ans cloud cover help cool that down. It will also cool as the amount of water spilling decreases over the next few days. The water temps have pushed the hatches later in the afternoon / evening. We have great weather today with clouds and light rain so that may push some bugs earlier. Streamers and nymphs continue to fish well.

Today will be 66 degrees with clouds and some rain showers in the morning. Total rainfall should be .03″. Wind will be 5 – 10 mph from the South.
