Delaware River Report: May 27, 2025

The release from Cannonsville is 600 cfs with 210 cfs spilling over the top. Yesterday was another good day on the water with nymphs and some streamers working well early and hatches in the afternoon. We’re still seeing a good mix of bugs hatching along with spinners. Sulphurs, cahills, March Browns, Gray Fox, some Green Drakes, olives, tan caddis, and dark grannoms have all been on the water in varying numbers. Today looks like another good day. We’ll have clouds and we can’t remember the last time Wunderground described the wind as “light and variable.”

Today will be 73 degrees with mixed skies in the morning turning to cloudy skies in the afternoon. Wind will be light and variable.
