Delaware River Report / Conditions April 23, 2021
The air temp should be close to 60 degrees this afternoon. We’re starting off around 30 but once the sun pops out things should warm up quickly. The wind will be up a bit between 10 and 15 mph fro the North. It will be a welcome change after the last two days. Yesterday there were some blue quills and hendricksons for a short while but the wind made it really tough. The the snow, sleet, and hail did not help either. Some fish were landed on nymphs in the afternoon. The 10 day forecast looks great with some really warm days coming next week. This week should fish really well.

The wind, rain, and snow made for challenging conditions yesterday. There were some fish landed on nymphs but it wasn’t easy. Today looks a little better with the air temp reaching the low 40’s. Rising temps are better than falling temps at least. We may see a little more snow this morning but mostly in the higher elevations. The wind will still be up. Looking ahead things turn back to normal tomorrow with the air temp reaching close to 60 degrees. The ten day outlook shows warm temps, some sun and rain, and no more snow.

Delaware River Report / Conditions April 21, 2021
The wind was not kind for dry fly fishing but yesterday worked out fine for nymphing. There were a few flushes of hendricksons and blue quills that happened in some calm periods so there were some dry fly shots. There are a lot of active nymphs in the rivers right now so that’s always a great way to start and a good back up plan. Use nymphs similar in size to the naturals hatching. It’s going to be cooler today with a little rain in the morning. We may see some snow showers in the afternoon. Wind will start from the South and turn from the North 15 – 20 mph as the front pushes in. Streamers and nymphs will be the best bets today. The air temp climbs back up Friday and looks great through the weekend.

Delaware River Report / Conditions April 20, 2021
Some people found awesome dry fly fishing on hendricksons yesterday while other people did really well nymphing. It sounded like a solid day to be on the water either way. The wind wasn’t kind for a little while in the afternoon but that didn’t seem to bother the bugs. If you don’t find fish by mid afternoon move around and check out other areas. The river flows are dropping slowly and everything is in great shape this morning. Today will be warm again hitting 60 degrees with a mix of clouds and sun. Wind will be 10 – 15 from the West which should be workable.

Delaware River Report / Conditions April 19, 2021
Some river sections saw decent Hendricksons mixed in with olives and blue quills yesterday. The little black caddis and a few stoneflies are still around too. The sections that didn’t report good Hendricksons reported really good olive hatches. It sounded hard to make a bad decision yesterday. Just about everyone we spoke with had some kind of good dry fly action. It’s cool this morning but should warm up into the low 60’s this afternoon. We have cloud cover and the chance of light rain. Light wind. Today should fish really well.

Most of the river fished yesterday with good hatches in the afternoon. Nymphing worked well in the morning but the olives and blue quills came in the afternoon offering good dry fly fishing. It was cold, wet, and unpleasant out for a while but well worth it for those who stuck it out. Today looks just as good but even warmer. We should hit the high 50’s with cloud cover and a chance of a shower. Wind will be 5 – 10 from the North. It should fish really well today.
It’s good to finally see solid hatching after the long winter. The 10 day forecast looks good for mid April.

Delaware River Report / Conditions April 17, 2021
Some of the river flows bumped up overnight from the rain but not enough to make a difference this morning. The water temps all seem to be within a degree of yesterday morning too. That leaves us with a decent start today. We’ll be close to 50 degrees this afternoon but may see a few snow showers before lunch. The precip. shouldn’t amount to anything. Wind from North 5 – 10 mph. Nymphing and streamers early will be your best bets early but keep an eye out for risers in the afternoon. The dry fly fishing has been picking up offering some good shots each day.

Delaware River Report / Conditions April 16, 2021
Yesterday afternoon we had a decent olive hatch with a few blue quill mixed in. Good olives. It was the happiest we have seen fish yet. The rain and overcast sky certainly helped keep the bugs on the water. The next few days look cloudy with little rain. The air temp is down a little but should be back over 50 degrees tomorrow. The eastern drainage flows are up a little from the rain but should begin to drop back. No rivers came up dramatically and everything looks good for the weekend.

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.

Early Black / Brown Stone – #14 – 16 – Taeniopteryx fasciiata, Brachytera sp.

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

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.

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.
