Delaware River Report: September 29, 2024
We woke up to some light showers that should end before lunch leaving u with a cooler, cloudy afternoon. The fog is patchy but thick in some areas. It should burn off in the next couple of hours. Olives made up most of the hatch again yesterday with some hebes mixed in. Some river sections are seeing Isonychias and a few cahills in the afternoons so blind casting riffles can still be a good bet. Nymphing was the better bet early yesterday. The tint on the West Branch is also making it a little better for streamer fishing.
Cannonsville is turning over so the West Branch has that green tint we get most Falls. It doesn’t bother the fish or the bugs.
Today will be 64 with morning showers turning into a cloudy afternoon. Wind will be light and variable.

The good weather continues with decent clouds and a chance of some light afternoon rain. We should see decent olives again mixed with hebes. There were a few Isonychias and cahills mixed in but the olives were the main hatch. Some river sections are seeing better bugs than others so if you’re not seeing much in the afternoon move.
Cannonsville is turning over so the West Branch has that green tint we get most Falls. It doesn’t bother the fish or the bugs.

Delaware River Report: September 27, 2024
Today looks like a good day to be on the water with no wind and clouds. Some sections have heavy fog but that should burn off in the next hour. Throwing streamers while the fog is still there could pay off early. Yesterday rain bumped the river flows slightly but it shouldn’t be noticeable. The hatches were good in the rain over the last few days mainly with olives and hebes. Some people are finding Isonychias and cahills on some river sections so it’s definitely worth blind casting if nothing is going on.
Cannonsville is turning over so the West Branch has that green tint we get most Falls. It doesn’t bother the fish or the bugs.

We were hit with some rain showers in the late afternoon and again overnight but the river flows barely bumped. We should see another 1/4″ today but that shouldn’t be enough to change anything. The East Branch, West Branch, and Mainstem are all at good levels. This looks like another good day for blue wing olives. We should also see some Isonychias, cahills, and hebes. Some river sections have had decent flushes of Isos this week. The West Branch has that greenish tint we get in the Fall but it doesn’t bother the fish or the bugs. It may actually help mask tippet on presentations.
Today will be 70 degrees with clouds and rain showers. Total rainfall should be .25″. Wind will be 5 – 10 mph from the South.

The clouds and occasional rain showers over last few days have done nothing to the river flows but it’s been a great break from the bright sun we had last week. The hatching has been good after the rains or during lighter rains. Olives, hebes, cahills, and Isonychias have made up the bulk of the bugs. There are some caddis around and we should see more as we get deeper into Fall. The rain should start early this afternoon.
Today will be 61 degrees with clouds and occasional afternoon rain showers. Total rainfall should be .25″. Wind will be 10 – 15 mph from the South.

Delaware River Report: September 24, 2024
Yesterday’s rain soaked into the ground with no affect on the river flows. The cloud cover and rain was a nice change and there were fish on the olives and hebes. Today looks similar with clouds, less rain, and a bit higher air temp. The rain will be negligible. Nymphing or swinging wets should be the best bets early. There have been some fish eating on top in some of the slower pools before the sun really hits the water. The afternoon hatches have mostly been olives with a few hebes. There are some Isonychias and cahills around. The caddis should pick up as we push deeper into Fall.
Today will be 65 degrees with clouds and slight chance of rain showers. Wind will be 5 – 10 mph from the South.

Big change in the weather with clouds, much cooler temps, and even a rain shower. The rain doesn’t look like much and should soak right into the ground. It should help by keeping the bugs on the water longer. We’ve had some minor mid day dry fly action followed by more in the late afternoon. Olives and hebes are making up most of the hatch but there are cahills and Isonychias in the mix.
Today will be 59 degrees with clouds and rain showers. Total rainfall should be .12″. Wind will be 5 – 10 mph from the South.

Again today will look like the last two days but just barely cooler so it should fish the same. Streamers should be a good bet before the sun hits the water. There’s also a shot of finding some surface feeding early. We’ve had some olive flushes in the sun but mostly in the late afternoon with a light mix of hebes, Isonychias, and cahills. If Wunderground is correct we should get some rain beginning tomorrow and lasting or a few days plus much cooler temps. That could push the fall bugs this week.
Today will be 75 degrees with a mix of sun and clouds. Wind will be light and variable.

Today will be a couple of degrees cooler than yesterday but otherwise it looks exactly the same. The West Branch has that Fall color we get when the reservoir starts to turn but the bugs and fish don’t care. There is less fog on the lower West than normal but it could still pay off to throw streamers before the sun hits the water. Nymphing or blind casting Isonychias or cahills should be good bets during the day. The hatches should happen mid to late afternoon with mostly olives and hebes mixed with a few Isos and cahills.
Today will be 77 degrees with a mix of sun and clouds. Wind will be light and variable.

We’re on a cooling trend over the next few days but today will be a lot like yesterday with sun and clouds. The weather has been pretty consistent so the fishing has been the same. streamers in the early morning before the fog burns off could pay off. Once the sun hits the water nymphing will be the best bet. There have been fish eating olives in the sun so keep an eye out early but the majority of the hatching has been in the late afternoon. Olives have been the strongest hatch but there are some hebes, cahills, and Isonychias.
Today will be 79 degrees with a mix of sun and clouds. Wind will be light and variable.

The rivers will be foggy this morning but it should burn off in the next hour or two. We should be left with some clouds for the rest of the day. Small streamers could be good before the sun hits the water. Once the fog burns off we’ll be back to the normal program of nymphing early with the hatches coming later in the afternoon. Some people are still finding a few fish mid day on small olives. Blind casting cahills and Isonychias in the riffles is always an option. We’re getting later in September but don’t leave the flying ants at home yet.
Today will be 82 degrees and partly cloudy this afternoon. Wind will be 5 – 10 mph from the North.

We’re going to start off with some sunshine this morning but the cloud cover should increase this afternoon. The forecast doesn’t show us getting any rain this week but clouds and no wind will be okay. We’ve had some decent fog in the mornings. If you’re up early enough throwing streamers before it burns off could pay off. Nymphing will be a better bet once the fog burns off. The clouds should roll in during the afternoon. The olive hatches have been decent along with a few Isonychias, cahills, and hebes. The intensity of the bugs has varied a bit form river section to river section.
The Beaverkill at Cooks Falls peaked at 68 degrees yesterday.
Today will be 76 degrees with a mix of clouds and sun early with more clouds in the afternoon. Wind will be light and variable.
