Delaware River Report: August 25, 2024
Flying ants were out yesterday and people were finding fish eating them. While not the biggest ant fall there were enough throughout the river to get fish looking up. towards dark we had the normal tiny olives mixed with a few Isonychias. There are still a few cahills and sulphurs hanging on too. Nymphing was the best bet early with the bright sunshine. Today’s weather looks a lot like yesterday so it should fish the same.
The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Mainstem at Lordville all peaked around 68 degrees yesterday. Today they will peak a little higher. It’s time to give these rivers a break again.
Today will be 82 degrees with sun and a few clouds. Wind will be light and variable.

We’re back on a warming trend with sun. The West Branch temps remain steady. The Beaverkill, East Branch and Mainstem are still okay but all are starting off two degrees warmer than yesterday morning. The sunshine will bump them up today. Nymphing is still the best bet early. The coldest water sections may see some dry fly activity a little earlier in the day. Once the sun drops we are seeing decent olives, a few sulphurs, and Isonychias. The Isos haven’t been heavy but the fish are looking for them in the evening. As it warms up this week we have a better shot at flying ants.
Today will be 80 degrees with sun and a few clouds. Wind will be light and variable.

The rain slid around us yesterday and all of the rivers are in good shape this morning. The cooler air temps and cloud cover over the last few days really helped the water temps on the Beaverkill, East Branch, and Mainstem. Today will be warmer with some sunshine but no wind for a change. Nymphing has still been the best bet early but we are seeing decent olives in the evening. Isonychias worked well last night as the sun dropped. The warmer weather coming should be better for the flying ants.
Today will be 77 degrees with a mix of clouds and sun. Wind will be light and variable.

Yesterday was a bit unsettled with rain showers and sunshine, sometimes at the same time. The rain wasn’t heavy and the rivers are in fine shape this morning. People found fish on a mix of nymphs and dry flies. Today will be a bit warmer with less wind and some afternoon clouds. The tiny olives have been consistent in the afternoon / evening mixed with some left over sulphurs, cahills, and Isonychias. There is always a shot at flying ants for the next month plus we should see the caddis hatches pick up with the cooler weather.
Today will be 71 degrees with a mix of clouds and sun. The cloud cover should increase in the afternoon with a slight chance of a rain shower. Wind will be 5 – 10 mph from the North.

The cooler air temps an cloud cover has really helped the water temps. Everything looks good this morning. Today looks a lot like yesterday with cool temps, maybe a rain shower, and some wind. The hourly forecast shows the wind dropping in the evening. Nymphing will be the best bet early with some possible streamer fishing. We’ve been finding fish on olives in the late afternoon and a few eating Isonychias. A lt of the olives are tiny but there are some #18’s around too. While today doesn’t look like the best day for them definitely have your flying ant box. A few Cahills and sulphur / Heptagenia should round it out.
Today will be 63 degrees, mainly cloudy, and a chance of a rain shower in the afternoon. Wind will be 10 – 15 mph from the North.

We’re in a cooling stretch with decent daytime temps and cloud cover today. The rain in the 10 day forecast looks negligible. That should definitely help keep the lower East Branch and Mainstem water temps in check. There is still a tinge of color on the the Main but it’s looking okay. The West Branch is in great shape and clear. Small olives and Isonychias have been around along with a few left over sulphurs. Flying ants have been spotted but we haven’t seen a big fall yet.
Today will be 64 degrees, mainly cloudy, and a chance of a rain shower. We m ay see some heavier showers in the afternoon. Wind will be 10 – 15 mph from the North.

We were hit with some storms overnight but the West Branch looks good with a flow of 662 cfs at Hale Eddy. It’s clear in Homepool right now. Oquaga Creek is only 50 cfs so it seems like we came through the storms just fine. The main storms must have passed just South and East of us because The lower East Branch and Mainstem are chocolate from the feeder streams. Olives, Isonychias, and maybe a few sulphurs and cahills should make up most of the bugs. The wind will be up a bit so look for protected areas. Nymphing will be the best bet early in the day.
Today will be 72 degrees with some rain showers in the morning. We m ay see some heavier showers in the afternoon. Total rainfall should be .26″ according to Wunderground. Wind will be 10 – 15 mph from the North.

We’d like to thank all of the volunteers that showed up for the 7th annual Get Trashed River cleanup. Over 90 people showed up to clean the river, sections, of road, and access points. It’s an amazing group that does a lot of good for the river system.
We have some light rain / heavy mist this morning. Wunderground is calling for afternoon thunderstorms and .59″ of rain but keep and eye on the radar in case they slide around us. We had a bit more rain than forecasted yesterday but the rivers held together and look good. There were some olives and Isonychias around. Sporadic rising fish in the riffles seemed happy to eat an Isonychia. If we do get the rain today it would probably make a decent streamer afternoon. Large amounts of flying ants are more likely to fall on humid days but definitely have them in your box.
Today will be 77 degrees with clouds and light rain showers in the morning developing into thunderstorms in the afternoon. Total rainfall should be .59″. Wind will be 5 – 10 mph from the South.

We woke up to some light rain. We should see showers on and off today but the total precipitation amounts shouldn’t bump the flows. The cooler weather and rain could push some olives and Isonychias so definitively have those in your box. Nymphing has been better on the cloudy days too. Streamers could be a decent option in this weather too.
The Main Stem, Beaverkill and lower East Branch are starting to warm up again now that the levels have dropped. Bring your thermometer if you’re fishing those areas.
Today will be 75 degrees with clouds and light rain showers. Total rainfall should be .18″. Wind will be 10 – 15 mph from the South.

The rivers are still dropping but the West Branch remains in good shape for wading and floating. Nymphing has been the best bet early but people have seen some fish eating junk / leftover spinners in the big, slow pools before the sun hits the water. Isonychias are still putting some fish in the net. Olives and flying ants are definitely on the menu now too.
The Main Stem, Beaverkill and lower East Branch are starting to warm up again now that the levels have dropped. Bring your thermometer if you’re fishing those areas.

The river is fishing well, even with the touch of color remaining in the water. We’ve found fish on nymphs, streamers and dries – depending on the time of day. Have your Isos, olives, cahills and a few spinners with you. The Main Stem, Beaverkill and lower East Branch are starting to warm up again now that the levels have dropped. Bring your thermometer if you’re fishing those areas.
Today will be 82 degrees with a mix of sun and clouds and a small chance of showers in the afternoon. Winds 5 – 10 mph from the West.

The flows are in good shape and the stain has cleared from most river sections. There are plenty of safe wading opportunities on the upper West and more will open up as the levels continue to drop. The higher water gave us good streamer fishing, but as it drops we’re back to nymphing early and looking for rising fish as the sun drops. Make sure to have a selection of small olives, Isos and caddis with you.
Today will be 80 degrees with a mix of sun and clouds. Winds 5 – 10 mph from the West.
