Delaware River Report / Conditions April 15, 2021
It’s going to be cooler today with the air temp reaching 50 degrees. We’ll see less than 1/4″ of rain according to Wunderground so the rivers should be fine. Wind will be 10 – 15 from the North. We warm up a bit more on Saturday but keep the cloud cover. There were some fish eating on top yesterday (or close to the top according to reports) so have a good selection of olive emergers ready in the late afternoon. Start off with either streamers or nymphs in the morning. In the late afternoon watch the slow foam lines in the big pools for subtle risers.
What’s Hatching:
Early Black / Brown Stone – #14 – 16 – Taeniopteryx fasciiata, Brachytera sp.
Tiny Black Stonefly – #18 – Capniidae sp.
Little Black Caddis – #18 – 20 – Chimarra sp.

Delaware River Report / Conditions April 14, 2021
It’s 35 degrees this morning but should warm up to the mid 60’s by the afternoon. We should see a mix of clouds and sun with a slight possibility of afternoon showers. Wind will be 5 – 10 from the South. This should be a good day to be on the water. The olive hatches have been better on overcast and rainy days. Nymphing and streamers will be your best bet early. The runoff from Sunday and Mondays rain is working it’s way down the system and our rivers flows have dropped slightly and are looking good

Delaware River Report / Conditions April 13, 2021
We had a little more rain yesterday afternoon and overnight. The river flows are up a little but not too bad. We should see most of them peak and begin to drop soon. The West Branch at Hale Eddy is at 627 cfs so it’s in good shape this morning. The weather will clear up today with sunshine, light wind, and 63 degrees. We may see some showers during the week but nothing that looks like it will add a lot water to the system. We found some fish eating olives yesterday in the rain. There were enough fish eating steady enough that you could target them and keep it interesting.
What’s Hatching:
Early Black / Brown Stone – #14 – 16 – Taeniopteryx fasciiata, Brachytera sp.

Delaware River Report / Conditions April 12, 2021
It seems like most of the rain went South of us and the river flows are in decent shape this morning. The West Branch at Hale Eddy is 569 cfs and beginning to drop. We may see another 1/4″ fall today before it clears up overnight and we’re back to sunshine tomorrow. Little black caddis, stoneflies, and a few olives are on the water. People are finding some rising fish in spots but most are coming to the net on nymphs and streamers. That should shift in the next week as the hatches intensify. The release from Cannonsville is 374 cfs.

We lost our friend Stevens back in the Fall so here’s a shot of him doing what he loved from pre Covid times.
What’s Hatching:
Early Black / Brown Stone – #14 – 16 – Taeniopteryx fasciiata, Brachytera sp.

Delaware River Report / Conditions April 11, 2021
Wunderground is calling for just under 1/2″ of rain today. It looks like the rain will fall all day which is better than a couple brief heavy storms. It should soak into the round for the most part. The cloud cover will be nice with the air temp hitting 60 and wind 10 mph from the South. Yesterday was slower than expected but people managed some fish. Nymphing and streamers were still the best bets but we have seen more olives over the last few days. The lower water should warm up faster and push the hatches a bit.
What’s Hatching:
Early Black / Brown Stone – #14 – 16 – Taeniopteryx fasciiata, Brachytera sp.
Tiny Black Stonefly – #18 – Capniidae sp.

Delaware River Report / Conditions April 10, 2021
The release from Cannonsville has been dropped and the West Branch flow at Stilesville shows 396 cfs this morning. Most likely that was done in anticipation of the rain this week adding runoff to the system. The last few warm days have really helped the water temps and most of the system is looking good this morning. The warm nights really help. We’ll hit the 70’s today and only drop into the low 50’s overnight. We should see some cloud cover in the afternoon but no rain until tomorrow. Wind will be 5 – 10 mph from the South. It looks like a great fishing day.
What’s Hatching:
Early Black / Brown Stone – #14 – 16 – Taeniopteryx fasciiata, Brachytera sp.

Delaware River Report / Conditions April 9, 2021
The release from Cannonsville was dropped yesterday afternoon and sits at 671 cfs this morning. It’s going to be cooler today with the air temp hitting 63 degrees. We will get some cloud cover which we’ve needed the last few days. Wind will be 10 mph from the South. We warm up to the 70’s again tomorrow with more sun. Still a lot of stoneflies and black caddis around so keep an eye for risers. Otherwise streamers and nymphs have brought the most fish to net. Nymphing seemed especially productive yesterday.
The water temps are getting better everyday. We should see good hatches soon.

Delaware River Report / Conditions April 8, 2021
Yesterday was the nicest day of the year so far. It was almost hot outside in the sun. Today looks just as nice. We’ll have sunshine, the air temp will hit 70 degrees, and wind will be 5 – 10 mph from the North. We’ll see some clouds push in tomorrow with the chance of a few showers. Streamers and nymphs are still the best producers but people are catching fish on stoneflies and small caddis too. The dry fly fishing will improve as the water temperatures climb over the next couple of weeks.

The release from Cannonsville has been cut back to 1,198 cfs. Cannonsville Reservoir is at 99.7% so the spill has stopped. The rivers are still dropping as the runoff subsides. We’re right around 30 degrees this morning but should hit 60 with some sunshine this afternoon. More wind from the North today at 10 – 15 mph. Wunderground shows the wind dropping tomorrow. That will be a huge help. Most of the fish are still being caught on streamers and nymphs. There are some stoneflies and caddis on the water so keep your eyes open.
Air temps look great in the 10 day forecast. We may see some rain towards the end ofthe weekend but chances are good that forecast will change.

Yesterday turned out to be a nice one. Good sunshine and the temp approached 60 degrees. The wind was tough at times but manageable. It was a nice day on the water. Today looks a lot like yesterday with sun, warm air temp, and wind. There were some bugs on the water but nymphing and streamers were still the best producers. The dry fly fishing should pick up as the water levels drop and temps rise. The air temps look great all the way into next week.
