Delaware River Report: June 12, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is 1,083 cfs spilling. The water temp at Stilesville dropped again overnight but it is still colder at Hale Eddy. As the spill lessens the water temps will drop more. Today will look a lot like yesterday except the wind will be out of the North. Nymphs, wets, and streamers will be the best bets early. Sulphurs, cahills, and caddis should make up the bulk of the bugs. And definitely have some Isonychias. The hatches have continued to be later in the evening and even in the dark. The weekend forecast keeps changing but the latest has a little rain over the weekend but not too much. The cloud cover and light rain should be good for the hatches.

Today will be 79 degrees with sun and clouds mixed. Wind will be 10 – 15 mph from the North.
