Delaware River Report / Conditions September 10, 2019
There was some dry fly action in the evening but early nymphing was the best bet in the sun. There is some color in the West Branch with the higher release so streamers are working too. Isonychas, lots of olives, a few caddis, a few cahills, and a few flying ants. Today should be similar to yesterday with a high of 72 degrees, wind 5 – 10 from the South, and maybe a few more clouds. We’re going to warm up tomorrow with some rain and then drop right back into our normal late summer / early fall weather pattern. Hopefully the rain and heat bring out good numbers of flying ants tomorrow.

Delaware River Report / Conditions September 9, 2019
The release from Cannonsville has been bumped up slightly again to 913 cfs. This is likely due to water needed to meet the Montague flow target. Wading is possible on some West Branch river sections and is fine on the Mainstem. Today’s weather looks like a repeat of yesterday with sunshine and a high of 72 degrees. Wind will be a non factor. Nymphing and wet flies will probably be your best bet until the afternoon olive hatches. Blind casting isonychias in the riffles may also be a good choice. The morning tricos are still around but fish rising to them seems to still be spotty. We’re still patiently waiting for a big flying ant fall but there are some around.

Thank you to all the participants and volunteers for another successful Hooked on Hope Paint the Upper Delaware Pink breast cancer retreat!

Delaware River Report / Conditions September 8, 2019
Well the release from Cannonsville has been increased again. It is 831 cfs this morning. The flow on the lower West Branch is still climbing as the higher release makes it down river but we should level out by the afternoon. We’re starting off cool again this morning at 50 degrees but should reach 70 by the afternoon. Clouds and wind 5 -10 mph from the North. That’s much better than the wind we dealt with yesterday. There were olives and a surprising number of yellow sallies out yesterday but the wind did not help at all. Nymphing was a decent bet but a few people found success on top.

Delaware River Report / Conditions September 7, 2019
The Stilesville gauge looks off so the release is steady at 450 cfs bringing the flow at Hale Eddy to 575 cfs. Good for floating and wading. We’re starting off at 48 degrees this morning but should hit 70 by late afternoon. The wind will be up a bit at 10 -15 from the North so adjust your plan accordingly. Nymphing has worked well during the day although some people are finding fish eating olives even in the sunshine. Most of the olives have been coming off in the late afternoon mixed with a few isos and cahills. There are tricos out again this morning but on these cold mornings they sometimes fall later than you expect so watch the tail outs once the sun hits the water.

Delaware River Report / Conditions September 6, 2019
Well it looks like NYC DEP has had enough of ramping the flows up and down. The release hit close to 1,200 cfs yesterday afternoon and was immediately dropped back to 450 cfs. The recording says 450 cfs release but the gauge at Stilesville shows a 387 cfs flow this morning. The flow on the lower West and Upper Main will continue to drop but everything is in good shape for wading already. Of course the quick bump in release pushed the weeds but they should have settled out for the most part. Fish were rising in the high water in the evening so they should be easier to reach today. We’re looking at 70 degrees today with a mix of clouds and sunshine. Wind 5 – 10 mph from the South. It looks like a great weather weekend. Olives, isonychias, and cahills are still on the menu. Definitely have your ants and yellow sallys ready just in case they hit the water.

The release from Cannonsville has been increase to 801 cfs. Probably a temperature bump because the Mainstem at Lordville hit 69 degrees yesterday. Today will be cooler with the air temp only hitting 73 degrees. We’ll have sunshine with wind 5 – 10 mph from the North. That’s actually better than yesterday when the wind mad fishing tough mid afternoon. A few storms threatened us but the precipitation was non existent here – just the wind. We’re still mostly fishing small olives, isonychias, and cahills. Some caddis are around but we’ve also been finding a lot of yellow sally stoneflies. Tricos have been spotty but they are still around. If you don’t find fish on them by mid morning move around to different river sections. They can also fall later than expected on cold mornings.

The release from Cannonsville has been increased to 550 cfs. The recording still says 450 but Stilesville is a steady 562 cfs this morning. The flow at Hale Eddy will rise slightly during the morning. Still a good level for both wading and floating. We have clouds this morning and may see a few storms push through around lunch time. The projected rain amount is only .08″ but keep en eye on the radar in case we get a couple of severe storms are in the area. Wind will be 10 – 15 from the South. Olives, isonychias, and cahills. We’re still only finding a few flying ants but caddis are around.

Delaware River Report / Conditions September 3, 2019
We had quite a bit of rain come down yesterday morning but most of it seemed to get soaked in to the ground. The rain stopped around lunch time and while the clouds came in and out during the afternoon the rest of the storms slid around us. The rivers are up a little this morning but look fine and are fishable and and at a decent level for floating and wading. The West Branch flow is dropping back slowly as the runoff subsides. Today should be partly cloudy, 77 degrees wit wind 5 mph from the South. Olives, isonychias, caddis, and maybe a few cahills should cover you today. We have seen a few flying ants around but have not seen a large fall on the river yet.

The release from Cannonsville has been cut back to 450 cfs according to the recording. The Stilesville gauge show 396 cfs.. It looks like they are counting on the rain to make up the flow difference. We’ve had some light steady rain so far this morning but nothing significant. The forecasted amount of rain today has been reduced to 1/2″ . This could turn out to be a good day on the water rather than a washout. High of 73 degrees with wind 5 -10 from the South. Yesterday fished well after the evening rain with really good olives, some isonychias, and even a few cahills showing. There were a lot of fish rising- a lot of small fish but if you were patient or lucky there were some good fish eating on top too.

September 1st and it’s 49 degrees this morning. Sections of the river fished well last night with olives and isonychias. It took a while to get going but we did find some nicer fish rising plus all of the small ones we’ve been seeing. Today looks good if Wunderground is correct. We’ll see partly a partly cloudy sky give way to clouds in the afternoon. The high will hit 73 degrees with wind 5 -1 0 from the south. There is a 20% chance of rian but only .13″ if it even happens. Blind casting isos would be a good move until the olives hatch. The weeds in the water from the release bump the other day made nymphing tough in spots but it filtered out enough to make it possible. The release from Cannonsville has been cut back a bit to 500 cfs.

Yesterday afternoon the release from Cannonsville was bumped up to around 950 cfs. It has been dropped back to around 679 cfs this morning so the West is back in good shape for both wading and floating. The sudden increase did dislodge weeds and dirt making it tough/ almost impossible to fish the upper river yesterday evening. That should flush out today with the lower release. The river looks fine out front this morning. We’re going to be cooler today with the high reaching 73 degrees. Sunshine with a few clouds. Wind will be 5 – 8 mph from the North.
