Delaware River Report: June 22, 2026

The release from Cannonsville is 500 cfs. The forecast changes everytime we check. This morning they are calling for .81″ of rain. It looks like it’s spread throughout the day with best chance mid morning. A light, steady all day rain would be okay. If the river flows change dramatically we’ll post an update. Click on the river gauge links below for the latest flow data. The clouds and rain could push some hatches earlier in the day. The hatches have been a mix of sulphurs, Cahills, Isonychias, olives, and some caddis. If we get some color in the water it could turn out to be a decent streamer afternoon.

Today will be 64 degrees with clouds and periods of rain. Wind will be 10 – 15 mph from the South.
