Delaware River Report: June 10, 2026

The release from Cannonsville is 500 cfs. We should see some cloud cover this afternoon with a chance of showers. Total rainfall should only be .03″ but the clouds will be a welcome change. The sulphurs were decent last night once the sun dropped a bit. March Browns, Gray Fox, Green Drakes, and Cahills are around on some river sections. We’re still seeing some tan caddis in the riffles. Hopefully they get active a little earlier in the day with the cloud cover. Blind casting midday did put some fish in the net yesterday but nymphing is still the best bet early. We should see some much needed rain overnight and tomorrow but not enough to affect the river flows. The West Branch is at a decent level for floating or wading. The East Branch above the Beaverkill is too low to float.

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 83 degrees and partly cloudy with afternoon rain showers. Wind will be 5 – 10 mph from the South.
