Delaware River Report: June 6, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is just under 800 cfs spilling. We had a few storms pass through overnight but most seemed to slide North of us. The West Branch flow bumped slightly but it shouldn’t be noticeable this morning. Today’s rain doesn’t look bad and the cloud cover and cooler air temp are welcome. There is a potential for some thunderstorms so keep an eye on the radar. The last few days of bright sun pushed the bugs later in the evening. Today’s clouds may push them back earlier. We’re still seeing good hatches with a wide array of bugs. Definitely have all of your sulphurs.

Today will be 75 degrees with clouds and some rain. Total rainfall should be 1/4″ but there may be some heavier bands pushing through. Wind will be light and variable.
