Delaware River Report: September 17, 2024
We’re in for a third day of the same weather. There will be some clouds around but mostly sunshine during the day. We should have some clouds come in overnight and last for the following couple of days. So it should fish the same today as yesterday with nymphing being the best bet early with small olives, some Isonchias and cahills, and hebes coming in the late afternoon. Some of the olives have been coming earlier and people are finding fish eating in the sunshine so it’s worth checking out before setting up the nymph rig.
The Beaverkill at Cooks Falls peaked at 70 degrees yesterday. It’s time to five the river a break until it cools back down.
Today will be 79 degrees with a mix of clouds and sun. Wind will be light and variable.

Today will look exactly like yesterday. We’re dealing with sunshine so nymphing or swinging wet will be the best bets early. We have found fish eating olives and Isonychias in the sunshine but it’s a bit spotty. Look for sections that get shade earlier in the day. Small olives, hebes, cahills, and Isonychias are making up most of the hatches. We are seeing some caddis. The forecast is changing constantly but it looks like we should have some cloud cover this week.

Delaware River Report: September 15, 2024
Yesterday afternoon people found success with a mix of nymphing and dry flies despite the sunshine. The hatches weren’t heavy during the day but some people found enough bugs to put fish in the net. The hatches are the same with small olives, Isonychias, some hebes, and a few cahills. Nymphing will still be the best shot early today but it’s worth looking around for sporadic risers first. The main hatch will be later in the afternoon as the sun drops.
Today will be 79 degrees with a mix of clouds and sun. Wind will be light and variable.

Delaware River Report: September 14, 2024
Today is going to be exactly like yesterday. Which was exactly like the day before. We’ll have sunshine, warm temps, and no wind. The rivers are in good shape with the higher releases and cool nights. We have seen some fish eating olives mid day in the sun but the majority of the dry fly fishing has been later in the afternoon. Olives mixed with some hebes and Isonychias have made up the bulk of the hatch. There are still some cahills around and there is always a chance for flying ants. We have some heavy fog on the river this morning but that should burn off in the next hour.
Today will be 82 degrees with mostly sunny skies. Wind will be light and variable.

Delaware River Report: September 13, 2024
Today is going to be exactly like yesterday with a few extra clouds. The rivers are in great shape with decent flows and temps. Conditions haven’t changed much so it’s fishing the same. Nymphing or swinging wets will be the best bet during the day. Some people are finding odd midday flushes of olives. Blind casting some riffles could also work. The olives should hatch in the late afternoon along with some hebes, Isonychias, and cahills. The warmer river sections may see some white flies. It’s definitely flying ant weather so have that box handy.
Today will be 81 degrees with partly sunny skies. Wind will be light and variable.

Today will be a little warmer with sunshine so nymphing will be the best bet once the the fog burns off. Blind casting Isonychias in the riffles could also be a good option. Look for areas that get shade earlier in the day. The olives have been hatching between 4 – 4:30 in the afternoon in good numbers. There are a few hebes, Isonychias, and cahills mixed in. The warmer weather over the next few days may bring the ants back in to play.
Today will be 77 degrees and partly cloudy. Wind will be light and variable.

We had a little rain after dark but not enough to bump the flows. All of the rivers are in great shape with decent water temps and flows. We’ll have a bit more sunshine today but the wind will be fine at 5 – 10 mph. So we’ll stick to the same program with nymphing or swinging wets early and dry fly in the afternoon. The olives have started between 3:30 and 4:30 most days with some hebes mixed in. There are some Isonychias and cahills around so blind casting the riffles could work well. We’re on a little warming trend this week so keep the flying ants in your box just in case. If you’re on the Mainstem have a couple white flies with you.
Today will be 72 degrees and partly cloudy. Wind will be 5 – 10 mph from the North.

Delaware River Report: September 9, 2024
The clouds should be back today and we may see some light afternoon showers. The wind will be way less than yesterday too so it looks like a good day to be on the water. Nymphing again will be the best bet in the morning but streamers could be an option with the clouds. In the afternoon we should see our normal hatches of small olives mixed with a few Isonychias, hebes, and the occasional cahill. The rivers are all in good shape with decent water temps due to the colder nights.
Today will be 68 degrees and cloudy with occasional afternoon rain showers. Total rainfall should be .1″. Wind will be 5 – 10 mph from the South.

We had some rain yesterday afternoon that bumped the flows slightly but not enough to be noticeable. The rain and cloud cover definitely helped yesterday and people landed fish on small olives and Isonychias. Nymphing and streamers also put fish in the net. We’ll have a bit more sun and wind today but the wind should drop back i the late afternoon into the evening. Water temps throughout the system are in great shape after another cool night.
Today will be 64 degrees and partly cloudy. Total rainfall should be .32″. Wind will be 10 – 15 mph from the North.

We finally have some cloud cover and rain in the forecast. The rain should start around noon with a total of .32″. It shouldn’t be enough to affect the rivers but hopefully it will push some bugs earlier in the day. Tiny olives, hebes, Isonychias and a few cahills are making up most of the bugs. There are some caddis starting to show up and that should get better over the next couple of weeks. Nymphing or swinging wets will still be the best option early. Streamers could be a good choice today with the weather.
Today will be 64 degrees with clouds and periods of rain. Total rainfall should be .32″. Wind will be 5 – 10 mph from the South.

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.
