Delaware River Report: June 8, 2026

The release from Cannonsville is 500 cfs. We had a cooler day yesterday but we’ll be warming up this week. We’re seeing some Sulphurs midday into evening, as well as Light Cahills and tan caddis. Try running a large dry flies through riffles earlier in the day if you’re not seeing rises. During midday, nymphing remains the most consistent action.

The Mainstem, the East Branch in Hancock, and the Beaverkill at Cooks Falls all peaked at or over 68 degrees again yesterday. It’s time to give these river sections a break until we cool back down.

Today will be 80 degrees with sun. Wind will be 5-10 mph from the South.
