River Reports

Delaware River Report: August 13, 2025

The release from Cannonsville is back to 500 cfs. It’s slightly cooler today and there’s a chance for thunderstorms this afternoon and some much needed rain. Look for olives hatching after the rainfall and try some blind casting in the riffles with Isos beforehand.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 82 degrees with some potential thunderstorms in the afternoon. Winds from the SW at 5 to 10 mph.

The release from Cannonsville is 720 cfs this morning as we received another overnight pulse of water. We expect it to drop back to 500 cfs later this morning. We’ll have another typically warm and sunny August day. Even though we have cool water near the dams and through the West Branch, the bright sun will make the fish wary. Look for shaded areas and have your olives ready for the evening.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 90 degrees and sunny. Winds light and variable.

The release from Cannonsville is 699 cfs this morning from the overnight pulse to cool down the Mainstem. That should taper back to 500 cfs later this morning. We’ll be warmer and sunny today once the fog burns off. The Upper West has had tiny olives with some Sulphurs midday. The lower West has had olives and some Isonychias and Cahills towards evening. We’ve seen small olive spinners in the evening so have a few options in your box for those last light fish.

The release from Cannonsville is 500 cfs. We’re in typical mud August conditions. We’ll have sun today with no wind. The Upper West has had tiny olives with some Sulphurs midday. The lower West has had olives and some Isonychias and Cahills towards evening. Blind casting bigger flies or nymphing have been the best bets during the day. We have seen some spinners mixed with the duns during the hatch so double check what the fish are eating if you’re getting refusals.

Delaware River Report: August 8, 2025

The release from Cannonsville is 500 cfs. We had a very brief but heavy rain shower yesterday afternoon but the river flows didn’t budge and the rain was absorbed in to the ground. Today looks like a repeat of yesterday. We’ll have sun and light wind. The Upper West Branch was mostly small olives yesterday with a few sulphurs. There is algae so if you want to nymph stay on the lower West. We’ve also had some hatchng towards dark on the lower West. Mainly olives with some Isonychias and a few Cahills mixed in.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 81 degrees and partly cloudy. Wind will be 5 – 10 mph from the South.

Delaware River Report: August 7, 2025

The release from Cannonsville is 500 cfs. We’re coming off a cool night and the water temps are starting off a couple of degrees cooler than yesterday. We should have a bit more sun so they’ll climb a bit this afternoon. So it’s the same, normal August program. Midday sulphurs and olives on the Upper West and Upper East. The bugs have been a bit spotty on some sections so if you’re not seeing much mid afternoon move up or down a couple of pools. If you want to nymph or swing wets stick to the lower West Branch due to the algae in Deposit. The lower West has been decent for blind casting Isonychias and Cahills and has had some hatching as the sun drops.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 81 degrees and partly cloudy. There may some smoke in the air causing some haze but it should be less than yesterday. Wind will be 5 – 10 mph from the South.

Delaware River Report: August 6, 2025

The release from Cannonsville is 500 cfs. We’re going to a bit cooler today with cloud cover but the best shot at daytime dry fly fishing will still be in the coldest water on the Upper West and Upper East. It’s mostly been sulphurs and small olives with the occasional Isonychia and Cahill. The lower West may some some Isonychias, Cahills, and olives towards dark but it’s mostly been nymphing and wets. Streamer have been okay before the sun hits the water.

The release from Cannonsville is back down to 500 cfs. That’s been the normal release fro most of the Summer and works well for floating and wading. Today’s weather will be very similar to yesterday with less wind. So stay on the normal Summer program. Midday Sulphurs and olives on the Upper West Branch and Upper East Branch. If the hatches come on the lower West they will be in the evening. Olives, Isonychias, and a few Cahills. Nymphing has been better on the lower West due to the Algae in Deposit.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

The release from Cannonsville is 600 cfs. The increase shouldn’t be noticeable and the West Branch is still in good shape for wading and floating. We’re in for another sunny day so normal early August conditions. The Upper East and Upper West will have the best shot at midday dry fly fishing with sulphurs and small olives. The lower West is better for nymphing and wets since there has been some algae up top. There are some Isonychias hatching sporadically throughout the river so working the riffles could pay off.

The release from Cannonsville is 500 cfs. We’re on a warming trend again. I won’t be as hot as last week but we’ll have warmer temps and sunshine this week. So back to normal Summer conditions. The midday Sulphurs and olives have been happening on the Upper West and Upper East. They’ve been a bit spotty in some sections so if you’re not seeing them move up or down a few pools. The lower West was fishing well with Isonychias and Cahills. They may push later in the day with the bright sun today but blind casting the riffles should work well.

Delaware River Report: August 2, 2025

The release from Cannonsville is 500 cfs. The rain mostly slid around us and the West Branch is in great shape this morning. The cooler air temps have dropped the water temps a few degrees too. The best midday dry fly fishing is still in the coldest water on the Upper West and Upper East. Sulphurs and olives are making up the majority of the bugs. The lower West is fishing with Isonychias and Cahills. Blind casting has worked well when there are no bugs on the water. We’ll have more sunshine today so work the riffles or nymph on the lower river.

The Beaverkill, Lower East Branch, and Mainstem water temps are still peaking in the mid to high 70’s. It’s time to give these rivers a break until they cool back down.

Today will be 76 degrees with lots of sunshine. Wind will be 5 – 10 mph from the North.
