Delaware River Report: June 11, 2026

The release from Cannonsville is 500 cfs. Most of the rain in yesterday’s forecast slid around us. Looking at Wunderground today it looks like it may do that again. We’ll have cloud cover with potential afternoon storms but total rainfall should only be .16″. The evening sulphurs have been the main hatch along with some Cahills, olives, and caddis. If you’re closer to the dams in the cold water you may still see some drakes.

Some of the water temps on some river sections are too hot to fish for trout. Some people (including some guides) will say that the Mainstem trout are used to warm temperatures and fishing to them in the high 60’s to 70’s is fine. We have never seen a study proving that and it’s really about greed and shows a total disregard for the resource. Please stick to fishing the colder water sections.

The Mainstem, the East Branch in Hancock, and the Beaverkill at Cooks Falls all peaked at or over 70 degrees again yesterday. It’s time to give these river sections a break until we cool back down.

Today will be 88 degrees and partly cloudy with potential afternoon storms. Wind will be 5 – 10 mph from the West.
