Delaware River Report: May 25, 2025
The release from Cannonsville is 600 cfs with 234 cfs spilling over the top. We had a few showers yesterday but the rivers came through fine again. It was an odd mix of clouds, light rain, sun, and wind. The flows are still dropping slowly and there are plenty of wade and float opportunities throughout the system. It looks like the cooler weather is past us and we should have warmer temps for the next week. Nymphs and streamers are still the go to in the morning. The hatch time has varied a little here and there but plan on being ready by early afternoon. The cloud cover and light rain showers could push them a little earlier.
Today will be 60 degrees, cloudy skies, with a few afternoon showers. Total rainfall over the day should be .02″. Wind will be 10 – 15 mph from the North.

The release from Cannonsville is 600 cfs with 339 cfs spilling over the top. The river flows are still dropping and the wade opportunities are opening up. We’ll have rain today but if Wunderground is correct and it’s only 1/4″ over the course of the day we shouldn’t see much of a bump in flows.

Not particular heavy hatching but enough to get some fish looking up. Today looks like an olive day.

The release from Cannonsville is 600 cfs with 1,625 cfs spilling over the top. We had a little rain yesterday that didn’t do much to the flows. The East West, and Main flows all dropped a bit while the Beaverkill bumped slightly. There is still no wading on the main rivers but are in great shape for floating. The Beaverkill and Willowemoc have the only safe wading right now. Yesterday fished well with streamers and some dry fly shots in the afternoon. It’s a good mix of bugs with Hendricksons still holding on in some sections and a few sulphurs showing on other sections. Today looks similar with good cloud cover and less wind. The rain totals will be negligible.
Today will be 74 degrees, overcast with a slight chance of a rain shower. Total rainfall should only be .12″. Wind will be 5 – 10 mph from the South.

The release from Cannonsville is 600 cfs with 2,209 cfs spilling over the top. The Beaverkill flow dropped below 1,000 cfs so there are some wad opportunities there and on the Willowemoc. The West, East, and Main flows are dropping but there are no wade opportunities. The cloud cover has helped the fishing and the rain totals look negligible for the next couple of days. There are some afternoon hatches offering some dry fly fishing. We are still finding some Hendricksons on some river sections along with March Browns. Bring your spinner box too. Nymphs and streamers are working when we’re not finding bugs. The wind will be up today but at least the leaves are now offering some shelter.
