Delaware River Report: April 21, 2025
The wind made things tough yesterday but there were some breaks that allowed people to capitalize on caddis and some mayflies. The air temps look great this week and we should see the water temps hit good numbers in the afternoon. that should push the Blue Quills and Hendricksons. There are olives and Quill Gordons out there too. The caddis have been active in the mornings before the wind picks up and in the afternoons if the wind drops.
Today will be 60 degrees with partially cloudy skies becoming cloudier in the afternoon. Wind will be 10 – 20 mph from the South.

People had some success dry fly fishing yesterday. Olives, little black caddis, Blue Quills, and even a few Hendricksons showed up. The wind was tough but there were enough breaks that the let the fish get happy. Nymphing also worked during the windy periods. A few decent thunderstorms pushed through in the late afternoon. The river flows bumped slightly from the rain but not enough to be noticeable. Today will be cooler but still respectable at 56 degrees. Wind may be an issue again but hopefully we get some breaks again.
Today will be 56 degrees with a mix of sun and clouds. Wind will be 10 – 20 mph from the North.

Delaware River Report: April 19, 2025
We had the bugs. Yesterday some river sections saw a mix of Hendricksons, Blue Quills, Olives, and Stoneflies. There were also some little black caddis around. The heavy winds pretty much defeated everyone and forced a nymphing day. Water temps look great, the bugs are getting better and better, and the rivers are in good shape for wading and floating. We just need a break from the wind. The river temps are up this morning and should climb today despite the clouds and light rain. Try to hide from the wind. It’s tough to hide without the leaves on the trees but look for sheltered edges, side channels, and bends below islands.
Today will be 80 degrees with cloudy skies. We may see some scattered thunderstorms in the afternoon. Total rainfall should be .1″. Wind will be 10 – 20 mph from the South.

Yesterday people landed fish on nymphs, streamers, and dries. The water temps are in great shape and it feels like things are really starting to happen. We’ll have some wind to contend with but the bright sun and warm air temp should push the water temps even higher today. It’s cool this morning but should warm up a little quicker today. Olives, small black caddis, and stoneflies should be out. We should see a few blue quills start to pop any day now.
Today will be 69 degrees with sunshine. Come clouds may move in during the afternoon. Wind will be 10 – 20 mph from the South.

We’re back on a warming trend and everything looks great trough the weekend. We’ll have some wind to deal with but that’s a small price to pay to have air temps back in the 50’s to 60’s. The water temps are starting off today a bit low due to the cold and cloud cover yesterday. The air temp and the sunshine today should push them back up by mid afternoon. Olives, little black caddis, and stoneflies should be out. Look for wind protected areas and take advantage of any breaks. Blue Quills should start to show with this warmer weather. Nymphing or streamers will be the best bets early.
Today will be 54 degrees with plentiful sunshine. Wind will be 10 – 15 mph from the North.

There is a light dusting of snow in the higher elevations but the river valley is clear this morning. We’ll be a bit colder today with wind so pick your spot accordingly. If the wind forecast is correct today will be a nymph and streamer day. We warm back up tomorrow and should see the sun. We have seen fish eating midges, stoneflies, and olives on the days with no wind so that should pick up as the weather gets nicer. Blue Quills shouldn’t be too far off.
Today will be 41 degrees with clouds and a few scattered snow showers. We should not see any accumulation. Wind will be 10 – 20 mph from the North.

The water temps bumped up quite a bit yesterday and are starting off in good shape this morning. The West Branch at the 191 Bridge is 47 degrees at 6:30 am. There were quite a few stoneflies and little black caddis in the air yesterday but not a lot hit the water. There were a few olives here and there too. A few people saw some rising fish but nymphs and streamers are what brought the fish to the net. The wind will be back today so try to find some protected areas.
Today will be 57 degrees with cloudy skies. We may see some showers this afternoon. Total rainfall should be .09″. Wind will be 10 – 20 mph from the West.

Today looks like a beautiful day to be on the water with decent air temps and less wind than we’ve seen in a while. The water temps should bump by mid afternoon despite the clouds. That could push some olives and bring the caddis off the bushes. Blue Quills can’t be far off so definitely have some in your box. Yesterday was a bit unsettled but there were some nice periods when the sun would poke through the clouds. Nymphing and streamers were still the best options.
Today will be 63 degrees with cloudy skies. Wind will be 5 – 10 mph from the South.

Today will be much warmer which is a welcome change. There is no snow in the forecast. The warmer next few days should help bump the water temps and hopefully push the hatches. The feeder streams are up a bit from yesterdays rain but it shouldn’t be noticeable on the West Branch. We’re still at decent levels for wading and floating. The wind will be up a bit so try to find protected areas with good slow foam lines. It’s still early in the season so nymphing and streamers will be the best choices but we are seeing some olives, little black caddis, and stoneflies.
Today will be 53 degrees with cloudy skies. Wind will be 10 – 20 mph from the North.

There is some snow falling this morning but we are above freezing so it should turn to rain before too long. Nymphing and streamers are still the best bets but there were some fish rising in the slow foam lines on some river sections. It was mostly olives with some stoneflies and little black caddis mixed in. Despite the snow falling this morning we actually will warm up today and we’ll see even better temps over the next few days. That should bump the water temps and push the hatches.
Today will be 42 degrees with a mix of rain and snow in the morning turning to rain in the afternoon. Total precip should be .11″. Wind will be 10 – 15 mph from the North.

We had some rain mixed with snow showers overnight leaving a light coating in the higher elevations. That should melt off this morning and turn in to a nicer day. We’ll have less wind than normal. We’re still mainly nymphing and throwing streamers. There are some little black caddis showing up along with the stoneflies and olives. We should see more as we warm up over the next four days.

Despite the cooler weather the West Branch at Hale Eddy peaked at 48 degrees yesterday. Not too bad for early April. We’re on a bit of a warming trend and should have cloud cover and some mixed precipitation through the weekend. Nymphing and streamers continue to be the best bets but people are seeing some olives and stoneflies. The fish we have seen eat on top have been in the foam lines and tailouts. The dries have been an occasional bonus so count on fishing underneath. The wind may pick up this afternoon so look for more protected spots.
Today will be 46 degrees, cloudy with a chance of rain this afternoon. Total rainfall should be .05″. Wind will be 10 – 20 mph from the South.
