Delaware River Report: October 6, 2025
The release from Cannonsville is 959 cfs. The release was cut back a bit which should make the lower West Branch a bit clearer. There will still be color but less than yesterday. Wading will also be a bit easier on the West today but the Mainstem will still have better wade options. It’s going to be another sunny day. Streamers and nymphs will still be the best bets early. We’ve been seeing a mix of bugs as the sun drops. Cahills, hebes, Isonychias, olives, and caddis are all in play. The amount of bugs has varied each day and the sun and warm temps may push them later in the day,
Today will be 81 degrees and sunny. Wind will be 5 – 10 mph from the South.

Delaware River Report: October 4, 2025
The release from Cannonsville is 1,349 cfs. The higher release means more tint in the West Branch. That should help the streamer fishing. Nymphing will also be a good bet early. Olives are making up the bulk of the bugs but there are Isonychia, Cahills, hebes, and the caddis are picking up. We’re seeing the hatches in the late afternoon in to the evening. Today’s weather looks good for spinners. Wading is getting tough on the West Branch but the Mainstem is relatively low so there there are good opportunities there.
Today will be 79 degrees and sunny. Wind will be light and variable.

The release from Cannonsville is 1,140 cfs. This is another situation where the system would benefit by splitting some of the release between the East Branch and the West Branch. The tint on the West Branch is still there and has been helpful for the fishing. Streamers and nymphs have worked during the day with the dry flies coming in the late afternoon / evening. Olives are making up the bulk of the bugs but there are Isonychichia, Cahills, hebes, and some caddis around. It’s starting to be a good Fall mix and the cooler nights should help.
Today will be 67 degrees with a mix of clouds and sun. Wind will be 5 – 10 mph from the South.

The release from Cannonsville is 1,362 cfs. The increase is to meet the flow target in Montague, NJ. This is another situation where the system would benefit by splitting some of the increase between the East Branch and the West Branch. The tint on the West Branch will be a bit darker today with the higher release. That keeps streamers as a viable daytime option despite the sunshine. Wading is still an option in some spots on the West Branch. The Mainstem is still relatively low and may be a better option. We’re seeing more caddis along with olives, Isonychias, Cahills, and hebes. The amount of bug has varied day to day. The best dry fly shots have been in the evening.
Today will be 67 degrees with sun. Wind will be 10 – 15 mph from the North.

The release from Cannonsville is 880 cfs. We’re having trouble with the flow gauges this morning but most rivers dropped a bit since yesterday and the West Branch flow is up about 80 cfs. The West Branch has the Fall tint to it from the Reservoir turning. It’s been helpful on the sunny days. We had more clouds than expected yesterday and bugs a little earlier than we’ve been seeing. It’s still mainly olives with some hebes, Isonychias, and Cahills mixed in. There have been spinners towards dark. Streamers and nymphs are both good options before the hatches.
Today will be 76 degrees with clouds and sun. Wind will be 5 – 10 mph from the North.

Delaware River Report: September 29, 2025
The release from Cannonsville is 771 cfs. They bumped us a bit higher yesterday afternoon and then dropped us back down. There is no rain in the forecast and the runoff is dropping so the release will likely stay at this level or higher for a while. The West Branch will have a pretty good tint to it at this release. It’s the normal color we get every Fall when the reservoir starts to turn or reaches a certain level. The fish and bugs aren’t bothered by it. It actually makes streamer fishing a more viable option and the fish should be a little more forgiving on dries. The small olives have been around in the late afternoons / evenings along with a few Isonychias and Cahills. Some riffles have decent Isonychia spinners at dark. It;s just a matter of being there when they hit the water.
Today will be 77 degrees with partly cloudy skies. Wind will be light and variable.

The release from Cannonsville is 350 cfs. The release from Cannonsville will likely stay there until water is needed to meet the Montague Flow Target. Montague is at 2,250 and dropping this morning so hopefully they’ll call for additional water soon. We had a few more clouds than expected yesterday. Nymphing was still the best option but streamers are still in play – especially in low light. The rivers have cleared and dropped back. There are still small olives in the slow foam lines along with some Isonychias and Cahills towards dark. Definitely have your Isonychia spinners if you’re fishing late.
Today will be 81 degrees with partly cloudy skies. Wind will be 5 – 10 mph from the North.

Delaware River Report: September 27, 2025
The release from Cannonsville is 350 cfs. All of the river flows dropped quickly and despite the rain all the rivers are starting off a little low this morning. The flow at Montague, NJ has peaked and is beginning to drop. Hopefully we’ll get a bump in the release in a few days after the runoff passes through. Nymphing and streamers worked well yesterday but there were some olives in the slow foam lines. There are still some Isonychias and Cahills around so blind casting the riffles could pay off.
Today will be 77 degrees with partly cloudy skies in the morning turning overcast this afternoon. Wind will light and variable.

The release from Cannonsville is 350 cfs. We got some much needed rain and the West Branch came through just fine and is still at a good level for floating and wading. The flow at Hale Eddy is 532 cfs. The feeder streams are adding a bit more below the gauge but overall we look good. We are off color but fishable. It will clear as the runoff subsides. Most of the runoff is on the Beaverkill and East Branch. We’re still seeing small olives. Nymphs and streamers were the best bets yesterday with some fish eating the olives in the slow foam lines.
Today will be 70 degrees with cloudy skies in the morning turning partly cloudy this afternoon. Wind will be 5 – 10 mph from the North.

Delaware River Report: September 24, 2025
The release from Cannonsville has be reduced to 350 cfs. We woke up to some light rain this morning. This is probably the best fishing weather we’ve seen in a long time. The feeder creek flows have bumped slightly but it won’t be noticeable on the river. The West Branch will still have the “tint” from the release but it should be less color than yesterday. The lower release should concentrate the bugs and fish a little more than we’ve seen in weeks. Olives and hebes are still making up most of the bugs but there are Isonychias, Cahills, and flying ants around.
Today will be 73 degrees with clouds and periods of rain. Total rainfall during the day should be .03″. Wind will be 5 – 10 mph from the South.
