Delaware River Report: June 16, 2026

The release from Cannonsville is 500 cfs. The flows have dropped back close to where we were before the rain. Water temps are starting off good this morning after the cooler nights. Some of the lower sections may still heat up from today’s sun. Yesterday was another odd one with the Sulphurs starting earlier in the afternoon than expected. Cahills, olives, and some tan caddis are around too. Nymphing or swinging wets have been the best bets during the day. Blind casting Isonychias or Cahills in the riffles could put a few fish in the net.

Today will be 65 degrees with sun and a few clouds. Wind will be 5 – 10 mph from the West.
