Delaware River Report: June 24, 2025

Cannonsville is spilling 730 cfs. The release from Cannonsville is 1,103 cfs. The increased release should help drop the water temps. The West, East, and Mainstem are still high but slowly dropping and clearing. The Beaverkill and Willowemoc both peaked over 70 degrees yesterday so please check water temps. They may cook today over there. Today is going to be another bright, hot day so plan accordingly. Nymphing and streamers early and hopefully a mix of Sulphurs, Cahills, and Isonychias in the evening.

Today will be 95 degrees sunny to partly cloudy. Wind will be 5 – 10 mph from the North.
