Delaware River Report: September 6, 2024
The cool weather combined with the increased releases has all the rivers in good shape. The West Branch is still at a good level for wading and floating. Small olives in the afternoon / evening has been bringing some fish up. We’re seeing some Isonychias, cahills, and hebes in the mix too. The caddis should pick up as we push into September. Today looks similar to yesterday with a few more clouds. Nymphing has still been the best bet early but we are finding fish on dries. We have some rain in the forecast tomorrow but it’s been dry and should mostly soak into the ground.
Today will be 76 degrees with a mix of clouds and sun. Wind will be 5 – 10 mph from the South.

Delaware River Report: September 5, 2024
The releases remain the same as yesterday. The releases were increased to drop the reservoir levels before the potential aqueduct work in October. The cooler nights have helped to and all of the rivers are in good shape this morning. The West Branch is fine ofr wading with a 619 release. Tiny olives have made up the bulk of the bugs but we are seeing some fall caddis show along with Heptagenia and the Isonychias. The hatches should get stronger as we move into Fall. As normal nymphing or swinging wets will be your best bet early. Look for spots that get shade earlier in the afternoon,
Today will be 75 degrees with sunshine. Wind will be 5 – 10 mph from the South.

The release from Cannonsville is 619 cfs until further notice. The release from Pepacton has also increased and the flow at Downsville is 609 cfs. The releases were increased to drop the reservoir levels before the potential aqueduct work in October. We’re coming off a cold night so river temps are good everywhere and the rivers all look good this morning. The colder water may push some of the fall hatches over the next couple of weeks. Heptagenias, smaller Isonychias, and olives should all be around. The sunshine may push them off until evening but there may be some shots during the day. Nymphing early will still be more productive.
Today will be 76 degrees with sunshine. Wind will be light and variable.

We’re cooling down again with the air temp only reaching 68 today and dropping to 45 overnight. That will definitely help the water temps on the Main, lower East, and Beaverkill. The West Branch and Upper East have been in great shape the whole Summer. Nymphing will be the best choice early. some river sections have seen some Heptagenia flushes in the afternoons. The olives and a few Isonychias have been coming in the evening when the sun drops – along with some cahills after dark.
Today will be 68 degrees with a mix of clouds and sun. Wind will be 10 – 15 mph from the North.

We had a few brief, light showers yesterday afternoon but not enough to affect the rivers. Nymphing or swinging wets will be your best bets early. Blind casting Isonychias or cahills in the riffles could also put some fish in the net. We should see the small olives hatching in the evening. We’ll have more sunshine today so look for places that get shade early in the afternoon. The sun could also push the flying ants so have those patterns with you.
Today will be 81 degrees with mostly cloudy skies in the morning and sunshine in the afternoon. Wind will be 5 – 10 mph from the South.

We’re in good shape with another cloudy day ahead of us. It’ll be a little warmer than yesterday. There is a chance of some thunderstorms in the late afternoon so keep an eye on the radar. It’s the end of August so nymphing will again be your best bet early. We have been seeing some olives in the evening and a few Isonychias. We’re not seeing huge numbers of Isos and cahills but the fish are eating them in the riffles. Definitely keep your flying ants handy for the next couple of weeks.
Today will be 76 degrees with mostly cloudy skies. We may see scattered showers and a thunderstorm in the afternoon. Daytime rainfall should be .02″ followed by .22″ after dark. Wind will be 5 – 10 mph from the South.

We had some rain overnight but so far the rivers look fine. The flows bumped slightly but it shouldn’t be noticeable. Oquaga Creek is only 19 cfs so the feeders are in good shape too. We have decent cloud cover and it definitely looks like a blue wing olive day. We should see a few Isonychias in the afternoon too. Blind casting worked well yesterday evening in the riffles. We have seen some cahills after dark this week so hopefully the weather pushes them a little earlier. As per normal this time of year nymphing or swinging wets will be the best bets early.
The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Mainstem at Lordville all peaked close to 70 degrees yesterday. It’s time to give these rivers a break again.
Today will be 68 degrees with mostly cloudy skies. We may see a stray shower. Wind will be 5 – 10 mph from the South.

Today we start to cool back down with a high of 73 degrees. We may see a stray shower but the steady showers should hold off until after dark. The cloud cover is a bonus again but nymphing and wets will still be the best options early. If we do a shower there is a shot of some olives being pushed early. Blind casting Isonychias in the riffles is still a good option if you want to fish dries. We’ve been seeing more olives as the sun drops in the evening. Plus there is always a shot at flying ants this time of year.

The forecast has changed a bit for the better. We’re still in a bit of a heat wave at 81 degrees but at least we should have some cloud cover today. Nymphing will still be the best bet early. If we keep the clouds blind casting Isonychias or cahills in the riffles could be a good option too. Once the sun drops we should see the olives and some Heptagenia. If we do get a rainshower and then the sun pops out for a bit the ants could come in good numbers so definitely have those patterns handy. The air temp cools back down considerably tomorrow.

Yesterday’s afternoon shower or thunderstorm never materialized. We had bright sun with just a few clouds. Nymphing was definitely the best bet until the sun dropped in the evening. Isonychias, olives, a few Heptagenia, and a few cahills are making up most of the hatches. Flying ants are definitely around but a bit unpredictable. Today will look a lot like yesterday with bright sun once the fog burns off. It should fish the same.

Wunderground is calling for a slight chance of a shower today but the hourly forecast shows mostly sunshine. So it should fish a lot like the last two days. Nymphing or swinging wets will be your best bets early. There may be some fish eating left over bugs in the bigger pools before the sun hits the water. We should see olives and a few Isonychias in the colder water sections. Mid to lower West Branch should see them as the sun drops. Flying ants can happen anytime and have worked well over the last few days.
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.
