Delaware River Report: May 28, 2025

The release from Cannonsville is 600 cfs with 169 cfs spilling over the top. Today looks like a great day to be on the water clouds, light rain, and light wind. Sulphurs, cahills, March Browns, Gray Fox, some Green Drakes, olives, tan caddis, and dark grannoms are all still in play. The weather may push the hatches a little earlier today. Water temps are great and the clouds / light rain should keep the bugs on the water. Nymphing has been working well before the hatches.

Today will be 63 degrees with clouds and rain showers developing. Total rainfall during the day should be .06″. Wind will be 5 – 10 mph from the South.
