Delaware River Report: June 1, 2023

The release from Cannonsville was increased slightly to 500 cfs. It’s the normal increase for June 1st under the current flow plan. Today is going to be bright and hot. Nymphing will likely be your best bet during the day until some shade hits some of he banks. Once the sun drops we are seeing a mix of bugs. Sulphurs, Light Cahills, March Browns, cornutas and a few Green Drakes are hatching. Dark Blue Sedges #14 are out in the evening (Psilotreta sp.). Keep an eye on the water temps. The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Mainstem at Lordville all peaked at or above 70 degrees yesterday,
