Delaware River Report: June 20, 2025

The release from Cannonsville is 801 cfs. The spill has ended on both reservoirs. The runoff is subsiding and all the rivers are in good shape this morning. We’re at good levels for wading and floating. The sun may push the hatches back a little again so some light rain and cloud cover would be welcome. Sulphurs, cahills, and Isonychias are making up most of the hatches. Blind casting Isonychias or cahills could payoff too.

Today will be 77 degrees and partly cloudy. There is a slight chance of a rain shower. Wind will be 10 – 20 mph from the North.
