Delaware River Report: October 15, 2025
The release from Cannonsville has been bumped to 1,100 cfs. There are still some wade opportunities at this level but the lower East Branch and Upper Main will have more comfortable wading. The feeder streams are dropping after the rain so the increase in release is to cover the minimum flow at Montague, NJ. The increased release means increased tim on the West Brantch. Streamers and nymphs will still be the best bets early. In the afternoon we’ve seen a light mix of Cahills, hebes, Isonychias, olives, and caddis. The caddis seem to be picking up.
Today will be 57 degrees with a few morning clouds giving way to afternoon sunshine. Wind will be 10 – 20 mph from the North.
What’s Hatching:
Slate Drake – #12 – 14 – Isonychia bicolor
Light Cahill – #14 – Epeorus vitreus (male), Ephemeralla rotunda, Ephemerella invaria

Delaware River Report: October 14, 2025
The release from Cannonsville has been bumped slightly to 723 cfs. The rain has been a non factor for us so far. Oquaga Creek is a steady 11 cfs and the Beaverkill has bumped 60 cfs. The West Branch is still in great shape for wading and floating an is mostly release. Nymph and streamers will probably still be the best bets early – es[ecially with the light rain falling. Cahills, hebes, Isonychias, olives, and caddis should all be hatching in some numbers later in the afternoon.
Today will be 63 degrees with a few morning showers and a few clouds sticking around in the afternoon. Wind will be 10 – 15 mph from the North.

The release from Cannonsville has been dropped back to 637 cfs. They bumped us to over 1k overnight and have now dropped us back.

Cahills, hebes, Isonychias, olives, and caddis are all hatching in some numbers later in the afternoon.

We shouldn’t see any rain today and the total predicted over the next few days has been decreased. The West Branch is still in great shape for wading and floating this morning. Nymph and streamers will probably be the best bets early. Cahills, hebes, Isonychias, olives, and caddis are all hatching in some numbers.

The release from Cannonsville has been droped back to 589 cfs. This was done n anticipation of the rain over the next few days meeting the Montague Flow Target. The West Branch is in great shape for wading and floating this morning. It should also clear a bit with the lower release. It looks like a good fishing day with some possible light showers in the afternoon. That could push the hatches a little earlier than we’ve been seeing them. Cahills, hebes, Isonychias, olives, and caddis are all hatching in some numbers.
Today will be 65 degrees and partly cloudy. Clouds should increase in teh afternoon and we may see a stray shower. Wind will be 5 – 10 mph from the South.

Delaware River Report: October 10, 2025
The release from Cannonsville is 1,109 cfs. We’re coming off a cold night and there is frost on the ground this morning. The high release from Cannonsville kept the West Branch water temps pretty steady. The other river temps dropped overnight and will take a while to warm up today. There are some spots okay for wading on the West Branch but floating is better at this level. The Mainstem and East Branch have better wade conditions. The West Branch continues to have the tint from the reservoir. It’s been a bonus for streamer fishing. Cahills, hebes, Isonychias, olives, and caddis are all hatching in some numbers. Streamers and nymphs will still be the best bets early.
Today will be 61 degrees with sunshine. Wind will be 10 – 15 mph from the South.

The release from Cannonsville is 1,003 cfs. The rain really helped the rivers and everything is in good shape this morning. The West Branch continues to have the tint from the reservoir. It’s been a bonus for streamer fishing. We’re in a cold snap for a couple of days so water temps are great throughout the system too. Cahills, hebes, Isonychias, olives, and caddis are all hatching in some numbers. Streamers and nymphs will still be the best bets early.
Today will be 55 degrees with sunshine. Wind will be 5 – 10 mph from the North.

Delaware River Report: October 7, 2025
The release from Cannonsville is 774 cfs. The release was cut back again most likely in anticipation of the rain helping meet the Montague Flow Target. It’s been a while since we had cloud cover and a chance of showers. It looks like a good day to be on the water. The West Branch should clear slightly with the lower release and there are more wade opportunities than yesterday. The rainfall during the day should be a few light showers. We may see .5″ overnight. It’s been really dry so a lot of that should soak in to the ground. Streamers and nymphs will still be the best bets early. Cahills, hebes, Isonychias, olives, and caddis are all in play. Hopefully the weather change pushes them earlier in the day.
Today will be 76 degrees with clouds and possible afternoon showers. Wind will be 5 – 10 mph from the South.

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,

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.

Delaware River Report: October 2, 2025
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.
