Delaware River Report: May 20, 2025

The release from Cannonsville is 600 cfs with 465 cfs spilling over the top. The river flows are still dropping and people are wading some areas of the West Branch now. Streamers and nymphs were the best bets yesterday because of the wind. There are march browns, gray fox, sulphurs, and caddis around if you can find a protected area. The cloud cover looks good for today and the wind will be a little lighter than yesterday.

Today will be 60 degrees. Partly cloudy in the morning giving way to clouds in the afternoon. Wind will be 10 – 15 mph from the North.
