Delaware River Report / Conditions August 12, 2021
Yesterday was a hot one but we did have some cloud cover that made it easier to bear. They’re messing around with the Cannonsville release a bit and Stilesville is around 550 cfs this morning. The fishing will be similar to yesterday with sulphurs and olives mid day in Deposit and nymphing with some evening activity on the mid to lower West Branch. Blind casting Isonychias and cahills should work if you don’t like nymphing. Today will be another hot one but we should have decent cloud cover by the afternoon. 50% chance of afternoon thunderstorms with wind 10 – 15 mph from the South. Much better than bright sun
The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Upper Mainstem all peaked close to or over 70 degrees yesterday. Those rivers are done for a while.

Delaware River Report / Conditions August 11, 2021
There was a quick pulse from Cannonsville that bumped the Stilesville flow to 650 cfs but that is already dropping back this morning. The extra 50 cfs won’t be noticeable as it works it’s way down the river. Yesterday’s thunderstorms missed us and we had a mix of clouds and sun most of the afternoon. The Upper West and very Upper East are still your best bet for daytime dry fly activity. Nymphing has produced on the mid to lower West Branch and we are seeing some flushes of olives, cahills, and a few Isonychias as the sun drops.

Delaware River Report / Conditions August 10, 2021
Yesterday wan another bright, sunny day. So it fished the same as it has been . Sulphurs with a few olives on the Upper West. Normal Deposit fishing. Be patient and if you can’t get the fish to eat throw something different just to mix it up. Mid to lower West was better nymphing than dries yesterday. There are some spots with caddis mixed with a few cahills, Isonychias, and olives. Not if great numbers but enough to get a few fish looking up in the evening. Today could be totally different Since we should see some clouds. Wunderground is calling for a 50% chance of some afternoon thunderstorms. We shouldn’t see a lot of rain out of it. Hopefully we get some light storms that push the bugs.

Delaware River Report / Conditions August 9, 2021
A clear sky and blazing sun made yesterday a tough one. Small flies and picky fish. Things picked up a bit once the sun dropped. Today looks similar with a high of 85 degrees and a mix of clouds and sun. Wind will be 5 – 10 mph from the South so that’s a little better than yesterday. Head close to dams for the coldest water during the day. That will be the best hatching. Sulphurs, small olives, isonychias, and cahills will make up most of the hatches. Small sulphurs and small olives are the most important. Definitely carry your flying ant box too.

Delaware River Report / Conditions August 8, 2021
Yesterday was a mix of haze and clouds so the water temps climbed but not as high as we thought they would. The lack of direct sun definitely helped. The upper river sections are still fishing with mid afternoon sulphurs plus a few olives and cahills. In the evening the lower West had some small olives hatching. A lot of fish are eating just under the surface thoughout the river so it’s a good tim eto play with wet flies or cut back your dries to make them sink in the film. Blind casting Isonychias in the riffles lets you fish big bugs with some success. We’ll have more sunshine today with a few clouds so watch those water temps on the East, Main, and Beaverkill. 84 degrees with light and variable wind.

Delaware River Report / Conditions August 7, 2021
Yesterday was hot and sunny. The sulphurs still hatched in Deposit. When they get real picky keep downsizing your patterns and find something very low profile. Some of the pseudos can be #16 and #28. The fish do get on them. Small wet flies can work when they’re eating just under the surface. A shaded bank really helps too. Today is going to be a lot like yesterday hitting 85 degrees. We may have a few more clouds and chance of an afternoon thunderstorm. Winds 5 – 10 mph from the South.
The Esat Branch at Fishs Eddy, Beaverkill at Cooks Falls, and Mainstem at Lordville all peaked close to or over 70 degrees yesterday. They are starting off warmer this morning than yesterday. Time to give these rivers a break again.

Delaware River Report / Conditions August 6, 2021
Yesterday was very similar to Wednesday. Sulphurs on the upper river sections mid day. Mixed with a few olives and Isonychias. If you were below Hale Eddy mid day it’s a mix of nymphing and or blind casting Isonychias or cahill patterns. In the evenings you have a good shot at cahills and Isonychias. We should pick up more cloud cover tomorrow according to Wunderground.
We’ll hit 86 degrees today with mostly sun. Wind 5 – 10 mph from the South.
The water temps started to creep up yesterday on the Beaverkill at Cooks Falls and on the Mainstem. Watch those temps today with the sunshine and heat.

Delaware River Report / Conditions August 5, 2021
Today looks like another sunny day with a few clouds here and there. Stick to the normal program for this release and stay near the dams for daytime sulphurs and then drop down to the mid or lower West for cahills, Isonychias, and a few olives. We are seeing some caddis back on the water. Nymphing has been effective during the day. If you don’t like to nymph we are finding fish blind casting Isonychias and cahills. The cool nights have kept a lot of water open to us so take advantage before the heat comes back. 79 degrees with wind 5 – 10 mph from the North. The overnight will be back down to 57 degrees.

The sun stuck around a little longer than we wanted but there were some passing clouds that helped the fishing. There is still mid day fishing on some sections with sulphurs, olives, and some Isonychias. Mid West Branch picked up with decent cahills and a few pseudos in the late afternoon. We’re also seeing a few golden drakes mixed in. Nymphing midday put some fish in the net too. Today looks the same as yesterday with a high of 77 degrees and sunshine. Wind will be 5 – 10 from the East. The cooler air temps have really helped the water temps. Especially the nights in he 50’s.

Water temps are holding on pretty well throughout the river system. People are spread out and finding fish in odd spots for the beginning of August. But if it’s sunny and you’re looking for daytime hatching your best bet is still to head close to the dams. Sulphurs, olives, and Isonychias. The lower river is fishing well on overcast and rainy days. Bright sun has made it tougher than normal. We’ll be cool again today at 76 degrees with light wind. We should see some decent cloud cover move in this afternoon.

We were hit with rain late yesterday afternoon that added some runoff to the rivers. The West Branch at Hale Eddy peaked around 800 cfs and is already dropping this morning. The rain did push olives and some Isonychias in the evening. The fish did get on them in the slow sections until the river colored up just towards dark. it cleared up overnight and Homepool looks good this morning. We’ll see more sun today with no rain. 74 degrees with wind 10 – 15 mph from the North.

Yesterday turned out to a beautiful day if not a little too sunny. If you’re looking for dry fly activity on the sunny days move up towards the dam where the water is coldest. The mid day sulphurs are still there along with olives and a few Isonychias. The lower river has been day to day but decent on rainy days. Wunderground is calling for a 90% chance of rain today. It looks like scattered thunderstorms so we may see between 1/4″ and 1/2″ of rain. Maybe. 75 degrees with wind 5 – 10 mph from the North.
