Delaware River Report: July 18, 2025

The thunderstorms missed us again and the West Branch looks good again this morning. It’s going to be 10 degrees cooler today and already feels much better outside. The best hatching will still be in the coldest water so 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.

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.

Today will be 77 degrees with clouds early and sun in the afternoon. Wind will be 10 – 15 mph from the North.

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

Slate Drake – #12-2xl – 12 – Isonychia bicolor

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.

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 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.

We had a little more rain yesterday afternoon but most of the storms slid around us. The West Branch looks fine this morning and is at a good level for floating and wading. There arr midday sulphurs on the upper river sections along with some olives, Cahills, and Isonychias. It’s cloudy and foggy this morning but it’s going to get sunny and hot this afternoon. Fish the coldest water for the best hatches. And look for areas that get shade early in the day.

Some thunderstorms hit us hard overnight and the rivers are high and off color. The best shot at clear water would be to get close to the dams above the feeder creeks.

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.

The release from Cannonsville has been dropped back to 549 cfs. We have good cloud cover again and the forecasted rain looks negligible at .18″. Overall it looks like a great day to be on the water. Just watch the radar in the afternoon. The midday Sulphurs are offering the best shot at dry fly fishing. The should be olives, Cahills, and Isonychias mixed in as well. The lower West has been a better bet for nymphs and wets but we may see some earlier bugs if we get the rain.

The release from Cannonsville has been increased to 750 cfs. The West Branch is in great shape and the cloud cover is a bonus. The midday Sulphurs are on the upper river sections along with some olives, Cahills, and Isonychias. Nymphing should be good on the lower West today with the clouds. Blind casting Isonychias or Cahills in the riffles is an option all Summer. Yesterday’s thunderstorms and showers missed us.

Some river sections have heavy fog this morning but that should burn off in the next hour or two. We’re looking at another normal July day so head to the coldest water for the midday Sulphur hatches. There should be some Isonychias, Cahills, and olives mixed in as well. The lower West will fish best with nymphs and wets. Blind casting Isonychias in the riffles would work for people who don’t want to nymph. We may some some sulphurs in the evening – especially if we et clouds and some stray rain showers.

We had a little lightening and a rain shower last night but the river flows barely bumped and everything looks fine this morning. We are seeing the midday sulphurs in the coldest river sections along with some Isonychias, olives, and Cahills. The lower West is in good shape for nymphing, swinging wets, or blind casting Isonychias. We’ve settled into the normal July fishing. The hatches on the lower West are towards dark with the same bugs as up top.

The release from Cannonsville has been cut back a bit to 549 cfs. Our power is back on. Look for the coldest water for a shot at dry fly fishing during the day. There have been some sulphurs and a few isonychias in the afternoon. The lower sections of river that are still cold enough to fish may have some bugs in the evening as the sun drops. So we’re in normal July fishing. Blind casting Cahills or Isonychias may pay off along with nymphing or swinging wets. Look for [laces that get shade earlier in the day. We do cool down and we should have more clouds as we come in to the weekend.

The release from Cannonsville has been cut back a bit to 549 cfs. We lost power in Thursday’s storms. It’s estimated to come back on Sunday at 11 pm. Hopefully. Today looks like another sunny hot day so look for the coldest water for the best hatches. Sulphurs, some Cahills, tiny olives, and Isonychias should be out there. Blind casting Isonychias and Cahills could be a good bet on the lower West Branch. Nymphing or swinging wets would also be a good bet. The normal Summer Delaware fishing is kicking in.
