Delaware River Report: September 9, 2022
The river flow are dropping back to normal and people are wading areas other than Stilesville again. The clarity is fine. The sun was out yesterday afternoon so nymphing worked well early. Small blue wing olives are still the main hatch but there are some Isonychisa, cahill/stenos, heptagenia, and flying ants around. We’re also seeing a few more caddis which means Fall is definitely coming. It’s really foggy this morning but that should burn off in the next hour or two. Today will be sunny hitting 80 degrees. wind will be light and variable.

Delaware River Report: September 8, 2022
We had some power issues on Winterdale yesterday. Everything is up and running today. We ended up with quite a bit of needed rain over the last two days. The flows are dropping back to normal and while there is some color in the lower West it’s clear enough for fish to rise if the olives hatch. Most of the fish netted over the last couple of days have been on streamers but there have been a couple caught on dries in the slower tailouts. Blue wing olives have still been the main hatch but we are finding some Isonychias and yellow sallies. Flying ants are unpredictable but are definitely around too. We’ll be 78 degrees today with a sight chance of a shower. Wind 5 – 10 mph from the North.

What’s Hatching:
Slate Drake – 12- 14- Isonychia bicolor

Delaware River Report: September 6, 2022
It’s been raining for almost 24 hours giving us a much needed soaking. The West Branch at Stilesville above most of the feeders is relatively unaffected like normal with a flow of 383 cfs. The feeder streams are pumping quite a bit of water so the flow at Hale Eddy is 1,560 cfs and is off color. We’re going to see a little more rain today but it should be less than 1/4″. If you’re wading your only real option is above the feeders in Stilesville. Floating is fine at these flows as long as there is no debris in the water. People will be throwing streamers this afternoon.
Keep an eye on the radar and the latest flow information. And use good judgement.
