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 88 degrees with sun and partly cloudy. Wind will be 5 – 10 mph from the South.

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

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.

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

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. Nymphing or swinging wets should work early. The cloud cover will be a bonus this morning. The wind will be up so look for areas that get some protection in the afternoon.

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. Sulphurs, Isonychias, and Cahills are making up most of the hatch. There are some tan caddis around too. The West is at a good level for floating and wading and the Upper East is at a good wade level. Keep an eye on the radar. We shouldn’t see much rain but there is a possibility of some afternoon thunderstorms.

The West Branch looks good out front this morning. We had some rain yesterday that bumped the flows and some creeks were putting some color in the river. They all dropped back to normal quickly and things look fine. We’re still fishing the midday Sulphurs in Deposit. Isonychias, Cahills, and olives are still in play too. Nymphing or swinging wets would be the best bets early. If we get more rain and the creeks throw color again we could have some decent streamer fishing. We may see some afternoon storms so keep an eye on the radar.
