Delaware River Report: April 17, 2026
The river flows are still dropping and the West should clear up even more today. It had a tint for most of yesterday but was fishable. Water temps are still high for April. It’s mostly been caddis and stoneflies still but there are some olives and a few blue quills popping. The bugs should push any day now. Nymphing and streamers are still putting fish in the net. It’s going to be cooler today which is a good thing. The last few days were too warm for mid April.
Today will be 70 degrees with clouds. There is a chance of a morning shower. Wind will be 5 – 10 mph from the West.

Delaware River Report: April 16, 2026
We had some rain overnight and most of the river flows bumped a couple hundred cfs. So not a huge deal and they should start to drop back this morning. It’s going to be another warm, sunny day. Water temps are looking great throughout the system and should climb higher with today’s weather. There’s some heavy fog this morning that should burn off quickly. Nymphs and streamers are still the most effective methods but the warmer water temps should push the olives and blue quills. There are some black caddis and stoneflies around.
Today will be 82 with a mix of sun and clouds. Wind will be 10 – 15 mph from the South.

Delaware River Report: April 15, 2026
We had some brief but violent thunderstorms move through last night. The river flows bumped a little. The rivers are still at decent levels so no real change. The river temps shot up in yesterday’s heat with most rivers hitting at least 50 degrees. Today’s weather looks very similar to yesterday’s so we should see another temp spike today. The warmer water should push the bugs this week. The lower water levels have opened up more nymphing opportunities too.
Today will be 80 degrees and partly cloudy in the afternoon. There is a chance of morning thunderstorms. Wind will be 10 – 15 mph from the South.

Delaware River Report: April 14, 2026
The release from Cannonsville has been cut back to 600 cfs. All of the rivers are now in good shape for wading and floating. It’s unseasonably warm this week so all of the water temps are starting off higher than yesterday morning. We’re starting to see some river sections peaking over 50 degrees. That should push some of the hatches. Today looks a lot like yesterday including the wind. Streamers and nymphs will be the best bets early. If you can find a spot protected from the wind definitely have your dry fly box with you.
Today will be 80 degrees with clouds and some light rain showers. Wind will be 10 – 20 mph from the South.

The flows are still slowly dropping and the rivers are in great shape. Water temps are starting off a couple of degrees higher than yesterday morning. We’re still mainly fishing streamers and nymphs but the dry fly fishing should pick up over the next week with the warmer temperatures. Try to find some spots that are sheltered from the wind. Today’s rain will be negligible at .05″.
Today will be 73 degrees with clouds and some light rain showers. Wind will be 10 – 20 mph from the South.

Delaware River Report: April 12, 2026
We’re back on a warming trend and it should be much more comfortable on the water today. We’re going to keep the same wind though except from the South. The reservoirs are pretty much done spilling and the river flows are dropping back accordingly. They are releasing 1,500 cfs on the West Branch hopefully to make a small void so it doesn’t spill after every small rain storm. There are still stoneflies around with a few olives. The little black caddis should pick up. Water temps should climb this week pushing more of the early hatches. Streamers and nymphs have still been the best bets in the wind.
Today will be 62 degrees with a mix of clouds and sun. Wind will be 10 – 15 mph from the South.

Tiny Black Stonefly – #18 – Capniidae sp.

Delaware River Report: April 11, 2026
It’s going to be much cooler today. We’re keeping the same wind as yesterday but it will come from the North. We saw quite a number of stoneflies yesterday but the fish didn’t really get on them in the sun and wind. Today should be similar so it looks like another streamer day with some nymphing possibilities. Cannonsville may have stopped spilling and / or the release has been cut back. The flow at Stilesville is 1,390 cfs.
Today will be 51 degrees with .01″ of rain possible. Wind will be 10 – 15 mph from the North.

The river flows are still dropping. Cannonsville and Pepacton are almost done spilling. The release from Cannonsville is 1,499 cfs. The Beaverkill and Willowemoc are at great levels for wading. All the rivers are starting off a few degrees warmer than yesterday morning. We should see them warm up quite a bit today. There were some stoneflies flying around yesterday but the wind was unkind. Definitely have a dry fly rod today in case we get some breaks in the wind. Streamers have still been the most productive.
Today will be 74 degrees with sunshine and clouds mixed. Wind will be 10 – 15 mph from the South.

Delaware River Report: April 9, 2026
It’s another cool morning in the high 20’s but we’ll hit 60 degrees this afternoon. Like yesterday it will take a bit for the water temps to climb today. The 10 day forecast doesn’t show any more nights below freezing. The flows are still dropping slowly. The Beaverkill and Willowemoc levels look great for wading. The reservoirs are still spilling but once that stops the tailwaters should drop to decent levels. Streamers are still bringing the most fish to net but nymphing will pick up as the water drops. As we warm up this week we should see a little dry fly activity too – if the wind lays down.
Today will be 60 degrees with sunshine. Wind will be 10 – 20 mph from the South.

We’re starting off this morning at 15 degrees but should hit 50 with sun by this afternoon. It’s going to take a while for the water temps to climb today. The river flows are still dropping slowly. The best wade opportunities are on the Beaverkill and Willowemoc. Cannonsville and Pepacton Reservoirs are still spilling. Wunderground is still calling for dry conditions for the next five days so we should see the rivers continue to drop. Nymphing should pick up with the lower water but streamers are sill bringing the most fish to net. Now that we’re warming up again we should see more fish eat on top this week.
Today will be 51 degrees with sunshine. Wind will be 5 – 10 mph from the South.

Delaware River Report: April 7, 2026
The river flows have dropped a bit more and there are wade opportunities on the Beaverkill and Willowemoc. The big rivers need a little more time but they are dropping. Water temps remain low after last nights cold. They shouldn’t climb much today with cloud cover and the cold air temp. We warm back up tomorrow and it looks like we stay warmer for the next 10 days. The higher water will keep streamers as the best bet. People are starting to nymph some spots. Once the warmer weather settles in and the water temps climb we should see the fish eating on top again.
Today will be 36 degrees with clouds and a possible snow shower. Wind will be 15 – 25 mph from the North.

Delaware River Report: April 6, 2026
Yesterday’s rain didn’t bump the flows much so we should see the rivers drop a bit over the next few days. We’re in for some cooler whether for a couple of days but no additional rain. Water temps are still cold so it’s mainly been streamers. Nymphing will pick up as the water drops. We have caught fish on dry flies on the less windy days. We seem to be progressing in to a “normal” Spring.
Today will be 43 degrees with clouds. We may see a few snow flurries. Wind will be 10 – 10 mph from the North.
