Delaware River Report: June 21, 2026

The release from Cannonsville is 500 cfs. We’ll have less wind today but we’re keeping the sun. Nymphing or swinging wets will probably be the best bets during the day. Blind casting Isonychias or Cahills in the riffles could payoff early even dry dropper rigs. The evening hatches have been a mix of sulphurs, Cahills, Isonychias, olives, and some caddis but the sulphurs have been the main bug the last few nights. If you can stay late for the hatches stay late.

Today will be 77 degrees with mix of sunshine and clouds. Wind will be 5 – 10 mph from the North.
