Delaware River Report: September 13, 2025
The release from Cannonsville is 733 cfs. We seem to be stuck in the same weather pattern for a bit. there were a few clouds yesterday but for the most part we’re dealing with cool nights and warm, sunny days. So the fishing hasn’t changed much in the last week. Nymphing or swinging wets will be the best bets during the day but you can blind cast Isonychias or cahills in the riffles. There have been some fish on little olives early in the afternoon but that has been spotty. Most of the dry fly fishing ill be later in the afternoon. Small olives and hebes have been making up most of the hatch but there are some caddis showing along with flying ants.
Today will be 78 degrees and sun and clouds mixed. Wind will be 5 – 10 mph from the West.
Sadly Ryan Geiges, a friend and former DRC guide, recently lost his battle with cancer. He will be missed by many – both off and on the water. There is a GoFundMe for Ryan’s family if you’d like to support them in this difficult time.

The release from Cannonsville is 607 cfs. We’re still in great shape for wading or floating. Conditions should be about the same as yesterday with less wind. We seem to be dealing with the same conditions everyday so we’ll just leave this: Nymphing or swinging wets will be the best bets during the day. If you’re looking for dry fly fishing early blind casting Isonychias or Cahills in riffles could pay off. In the afternoon we’ve been seeing good olive hatches along with hebes. We haven’t seen huge flying ant falls (likely due to the weather) but there are out there.
Today will be 76 degrees and sun and clouds mixed. Wind will be light and variable.

The release from Cannonsville is 450 cfs. We’re back in to want sunny days and cool nights. Nymphing or swinging wets will be the best bets during the day but people have found fish eating tiny olives during the day in the slow pools. A few clouds would definitely help. The olives have been coming in the afternoon. There are a few Isonychias and Cahills around. Some fish are eating them so it’s worth a shot if you don’t want to fish tiny olives. Flying ants are always a possibility this time of year.
Today will be 73 degrees with abundant sunshine. Wind will be 5 – 10 mph from the South.

Delaware River Report: September 8, 2025
The release from Cannonsville is 520 cfs. Yesterday was a mix of small olives and hebes. Heavy on the olives. Some fish were willing to eat Isonychias and Cahills but the small olives were definitely the preferred bug. Today looks similar to yesterday with a bit more sun. Nymphing or swinging wets will be the best bets during the day but keep an eye on the slow pools for fish sipping super small olives or flying ants.
Today will be 68 degrees with sun and a few clouds. Wind will be 5 – 10 mph from the North.

Delaware River Report: September 7, 2025
The release from Cannonsville is 453 cfs. Montague is 1,580 cfs after the rain and climbing slowly but should level off soon. The release should be higher. Most of that rain missed us. We ended up with great conditions yesterday with good cloud cover and occasional light rain. The olive hatch was good with some hebes mixed in. The fish are also eating Isonychias, Cahills, and flying ants. We’re starting off showing the fish the bigger bugs and dropping down to the olives when necessary. We’ll have more sun today but the bugs should still come in the afternoon.
Today will be 68 degrees with clouds in the morning clearing to partly cloudy in the afternoon. Wind will be 5 – 10 mph from the North.

Delaware River Report: September 6, 2025
The release from Cannonsville is 450 cfs. It looks like they are still anticipating the rain adding enough runoff to meet the flow target in Montague, NJ. Most of that rain seems to miss us so we’ll see. It looks like a good olive day. We have clouds and little rain in the forecast. The wind will be less than yesterday. A lot of the fish eating olives seem just as happy to eat and Isonychia or Cahill so definitely have those in your box. There are some hebes on some river sections. Flying ants are always a possibility this time of year.
Today will be 69 degrees with some rain in the morning and possible scattered thunderstorms this afternoon. Total rainfall should be .17″. Wind will be 5 – 10 mph from the West.

Delaware River Report: September 5, 2025
The release from Cannonsville is 450 cfs. The release was likely dropped in anticipation of the rain adding enough runoff to meet the flow target in Montague, NJ. Most of that rain seemed to miss us. None of the gauges are showing a significant bump and most flows have peaked and are falling. Keep an eye on the Stilesville gauge in case they increase the release today to hit the flow target in Montague. The lower water should make nymphing and blind casting dries more effective. And concentrate the bugs in the afternoon / evening. Olives, Isonychias, Cahills, and hebes are out. have some flying ants with you just in case.
Today will be 79 degrees and cloudy. It will clear to partly cloudy in the afternoon. . Wind will be 10 – 15 mph from the South.

The release from Cannonsville is 495 cfs. The release was likely dropped in anticipation of the rain adding enough runoff to meet the flow target in Montague, NJ. Nymphing or swinging wets will likely be the best bets during the day. The wind will be a bit of an issue so look for protected areas. If the wind drops in the evening or you do find protected areas during the day we should see decent olives. There are also some hebes, Isonychias, and Cahills so have those ready just in case.
Today will be 78 degrees and partly cloudy. We may see some afternoon thunderstorms with rainfall of .19 during the day and another .34 overnight. Wind will be 10 – 20 mph from the South.

Delaware River Report: September 3, 2025
The release from Cannonsville is 709 cfs. The lower release will make wading easier but still keeps us at a good level for floating. The cooler nights have really helped the water temps on the other rivers opening up more fishing options. Nymphing or swinging wets will likely be the best bets during the day. We’ve seen decent olives most afternoons mixed with hebes, Isonychias, and Cahills. The fish seem happy to eat the bigger bugs even when we’re not seeing them.
Today will be 77 degrees with sunshine and a few afternoon clouds. Wind will be light and variable.

Delaware River Report: September 2, 2025
The release from Cannonsville is 935 cfs. The release was most likely bumped up again to meet the 1,750 cfs flow target at Montague, NJ. The West Branch is fine for wading and floating but choose your wade spots carefully. The Upper Mainstem is fishing and is at a great level for wading. Olives have mad up the bulk of the hatch but a lot of fish are willing to eat Cahills and Isonychias. Blind casting the riffles has also been working. We’ll have a bit more sun than yesterday so nymphing or swinging wets might make the most sense during the day.
Today will be 75 degrees and partly cloudy. Wind will be light and variable.
