Delaware River Report: July 8, 2024
The release from Cannonsville has been increased to 800 cfs. The release will be stepped down back to 500 cfs beginning at 8 am. This is likely to prevent the Mainstem at Lordville temp from exceeding 75 degrees. We’re in for another bright day. Sulphurs and olives in Deposit will be your best shot at midday dry fly fishing. There is algae up there and with the bump in release nymphing will be hard. Nymphing will be best on the mid to lower West after the algae settles. Towards dark we should see some olives, cahills, and Isonychias into dark. Sometimes the push of cold water can push the bugs a little earlier so there may be some afternoon dry fly fishing. Find the banks that get shade the earliest.
Today will be 89 degrees with sunshine. Wind will be light and variable.
The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Mainstem at Lordville water temps are all starting over 70 degrees this morning. It’s time to give these rivers a break.

The lower West has cleared after the slug of runofff pushed through yesterday afternoon and it looks good this morning. We’ll have a lot of sunshine to day so nymphing or swinging wets will be the best bet on the mid to lower West. We should see olives, sulphurs, some cahills, and some Isonychias once the sun drops. The upper West has some midday sulphurs and tiny olives. There has been some algae up top so it is more of a dry fly play.
Today will be 86 degrees with sunshine and a few clouds. Wind will be 5 – 10 mph from the North.

Noon Update: There is color in the lower West Branch as the runoff passes through. It should begin to clear as the flows drop.
We had some rain overnight and the flow at Hale Eddy is 938 cfs. It is already dropping back. As of 6:30 am it’s clear out front. If that changes we’ll post an update. The flow at Stilesville is still 509 cfs. We had some color in the lower West yesterday and some people did well throwing streamers. There was some dry fly action in the evening. The daytime sulphur hatches are offering some mid day shots closer to the dams. There is algae in Deposit so nymphing is tough on the upper river.
Today will be 86 degrees with sun and clouds mixed. Wind will be 5 – 10 mph from the South. There is a slight chance of a stay afternoon shower.
The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Mainstem at Lordville water temps all peaked at 70 degrees or higher yesterday. It’s still time to give these rivers a break.

We had a little rain overnight that barely bumped the flows. The cloud cover looks good today and should be good for the fishing. Nymphs or wet flies are still the best bets early. Blind casting Isonychias or cahills in the riffles would be a good bet too. There are some daytime sulphurs mixed with olives up close to the dams offering some dry fly shots. The rain in today’s forecast looks negligable but it may push some hatches a little earlier.
Today will be cloudy with a high of 84. Winds light and variable. There may some scattered thunderstorms in the afternoon but Wunderground is showing the total precip as .04″.

Happy Fourth of July! The fly shop is open this morning.
The sun yesterday didn’t help the hatches or the water temps. There were opportunities but waiting until dark was the best option. We are starting the day with clouds and scattered rain around the area. Hopefully the clouds will stay – great for fishing, less desirable for July 4th parties. Have your summer mayflies ready – sulphurs, Isos, cahills, olives. Look out for spinners in the last light.
Today will be cloudy with a high of 83. Winds light and variable from the South and WSW.

Yesterday was a typical sunny summer day. Your best bet is nymphs or wet flies in the morning, looking for the midday dry fly hatches into evening. Once the sun starts to go down, the activity should pick up. Bring an assortment of summer mayflies – sulphurs, Isos, cahills, olives. Add a few caddis for variety and spinners for the late day.
Today will be sunny with a high of 81. Winds 10-15 from the South.

We got reports of decent hatches yesterday. The sulphurs are going strong, but bring a selection of summer mayflies (Isos, cahills, olives) as well as some caddis. Keep some spinners handy for the evening.

Another round of thundersrtorms hit us yesterday morning. This raised the flows on the Beaverkill and lower system but had little affect on the West.
The summer mayflies are still hatching. Make sure to bring a variety of sulphur patterns as well as cahills, Isos and some different sizes of olives.
Partly cloudy today with a high of 73. Winds 10 – 15 mph from the North, dropping in the evening.

We got some much needed rain yesterday. We had light showers early in the day, followed by a heavier patch in the afternoon and evening. While most of the rain soaked into the ground, the Beaverkill did see some increased flow – though it remains warm. The West branch is clear this morning out front.
In the rain yesterday, fish were still eating sulphur patterns. You’ll want to bring your summer box of sulphurs, cahills, Isos and olives with you. Don’t forget to pack a few spinners.
Starting with some fog over the river this morning with a chance of scattered thunderstorms in the afternoon. Winds 10 – 15 mph from the West, with higher gusts during the storms.

Yesterday’s temperatures were a welcome relief from the hot days we’ve had so far. The wind was tough and didn’t relent until late into the evening. However, the bugs were still hatching and less fussy about presentation.
We saw plenty of sulphurs in the afternoon on the lower West Branch. Cahills, Isos and small olives were also mixed in. Bring along a few caddis today if you’re out midday.
Today will be 76 degrees and mostly sunny. Wind will be 5 – 10 mph from the East and much more manageable.

The storms last night were mild here and mostly slid south of us. We got far less rain than they forecast so there’s little impact to the flows, except for a little bump on the East Branch. However, the air temperature is a lot cooler this morning.
With the cooler temps, we should hopefully see good hatches today. Carry your sulphurs and a good selection of your summer variations – cahills, Isos, small olives and some caddis.
Today will be 73 degrees with clouds in the morning and sun in the afternoon. Wind will be 10 – 15 mph from the Northwest.
