Delaware River Report: June 19, 2026

The release from Cannonsville is 500 cfs. The wind was rough yesterday but did drop in the evening. We had a very brief heavy rain shower but the rivers came through just fine. The flows and temps are starting off roughly where they were yesterday morning. We’re in the time of year when blind casting Isonychias or Cahills in the riffles could payoff early. The evening hatches have been a mix of sulphurs, Cahills, Isonychias,olives, and some caddis.

Today will be 76 degrees and partly cloudy. Wind will be 10 – 20 mph from the North.
