Delaware River Report: June 20, 2026

The release from Cannonsville is 500 cfs. Today looks like it will be very similar to yesterday but with a few more clouds. The wind will be up druing the day again but the hourly shows it dropping towards dark. Nymphing or swinging wets will probably be the best bets during the day. 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 75 degrees with mix of sunshine and clouds. Wind will be 10 – 20 mph from the North.
