Delaware River Report: July 26, 2025

The release from Cannonsville is 549 cfs. Yesterday’s storms were a non factor and the rivers are starting off about where they were yesterday morning. We should get some afternoon cloud cover today but no precipitation until after dark. There are still midday sulphurs and small olives hatching in the coldest river sections. That’s still the best bet for rising fish during the day. There have been some olives on other river sections so keep an eye out for risers if you’re nymphing the lower West. Blind casting Isonychias and Cahills is still paying off on the mid to lower West Branch.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 83 degrees and partly cloudy early and cloudy this afternoon. Wind will be 5 – 10 mph from the South.

It’s that time of year. August 15 – 16. Let’s clean up the river!

Delaware River Report: July 25, 2025

The release from Cannonsville has been dropped back to 549 cfs. Yesterday’s increase was just a pulse to cool the Mainstem at Lordville. We’re back to normal levels and in good shape for wading and floating. It’s going to be hot again today so look for spots with shade in the afternoon. The midday sulphurs and olives should come off in the coldest water. The lower West has been better for nymphing and blind casting with some sulphurs, olives, Cahills, and Isonychias coming off at dark or in the dark. We may see some thunderstorms today so keep an eye on the radar.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 85 degrees and partly cloudy early. We may see some scattered thunderstorms with stronger winds in the afternoon. Total rainfall should be .15″. Wind will be 5 – 10 mph from the North.

Delaware River Report: July 24, 2025

The release from Cannonsville has been increased to 750 cfs. The increase was most likely done to keep the water temp at Lordville from exceeding 75 degrees as we head into to a few days of warmer air temps. It’s still a decent level or floating and wading in most spots. The fishing should remain unaffected with midday sulphurs and olives in the coldest water sections of the Upper West and Upper East Branches. That will be the best dry fly fishing. It shouldn’t be enough to push hatches earlier on the lower West so that should fish the same. Nymphing or singing wets will be the best bets along with blind casting Isonychias and Cahills in the riffles.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be a little warmer and we’re keeping the sunshine. It should fish just like it did yesterday. Midday Sulphurs in the coldest water will be your best bet for dries. There have been some small olives mixed in so watch the fish rising to make sure they’re actually eating the sulphurs and not something else. Nymphing and swinging wets will be the best bets on the mid to lower West. Blind casting Isonychias and Cahills in the riffles could work too. There is a shot at spinners and some hatching as the sun drops and in to dark.

We’ll be cooler today but with sunshine. It’s July fishing so go the cold water on the Upper West or Upper East for the best hatching. Sulphurs should start between noon and 2 pm. The could be some smaller olives mixed in so keep an eye out for those. No wind so we may see some spinners in the evening. The lower West could fish in the evening but during the day it’s been nymphs and wets. Blind casting Isonychias and Cahills has worked this week.

The thunderstorms slid South of us but we did get the cooler weather. It’s still normal July fishing so go the cold water on the Upper West or Upper East for the best hatching. Sulphurs are still the main hatch but we are seeing some olives and sporadic Isonychias and Cahills. The lower West has been better for nymphing or swinging wets. Blind casting Isonychias or Cahills has also brought some fish to the net. The rest of the week looks clear and we warm back up so that program shouldn’t change.

We have clouds and fog to start off this morning. The forecast has been changing a lot but right now we may see some scattered afternoon thunderstorms. Total rainfall should be .17″ but we may see the wind pick up as they pass through. Despite the couds the best shot at hatches will be the afternoon sulphurs on the Upper West and Upper East. We may see some bugs on the lower West if we get the rain. The clouds should help the nymphing and blindcasting.

Last night was cool for a change and the water temps are starting off a couple of degrees colder than yesterday morning. We have some fog on the river but that should burn off quickly. It’s going to be sunny again so look for areas that get shade earlier in the afternoon. It’s normal Summer fishing so the best hatching will still be in the coldest water. The Upper West and Upper East are the two best bets during the day. Midday sulphurs are on mixed with some olives, Isonychias, and Cahills. There are a few tan caddis around as a bonus. The lower West is in great shape for nymphing or blind casting bigger flies through the riffles.

Yesterday’s thunderstorms missed us. The West Branch is in good shape for floating and wading. The Upper East is in good shape for wading. Midday Sulphurs and olives are hatching in the coldest river sections along with some Cahills and Isonychias. Blind casing the larger flies on the lower river sections could payoff.

We should have decent cloud cover today. The best daytime hatching is still going to in the coldest water. We may see some bugs on the lower West if we get a nice steady rain shower.
