It doesn’t have to be competitive or stressful– you can simply wade out into the water and cast a line and enjoy being one with nature. Plus, you can plan your own trip with this DIY guide to fly fishing the West Branch Ausable River in New York.

About West Branch Ausable River

Fly fishing the West Branch Ausable River in New York

The West Branch Ausable River is a must for any angler who wants an authentic Adirondack experience when it comes to fly fishing. This river is a premier destination and perhaps one of the most popular for fly fishing, in particular, in the eastern U.S. Upper parts of the river pass through private lands and the Adirondack Forest Preserve, which offers plenty of public fishing access for anglers. 

The Ausable River comprises three sections in total: East Branch, West Branch, and Main Branch. This guide focuses on the West Branch Ausable River fly fishing opportunities. This branch is known for large trout and has become one of the best trout streams east of the Mississippi. 

There are sections of West Branch that are designated for catch-and-release only, artificial lures only, and other regulations. Many are open year-round. The Ausable River Association encourages conservation and has provided wader wash stations along the river during the summer months to allow anglers to clean their waders before entering the water.

The Ausable River Association is also involved in conservation efforts of wild brook trout throughout the region, in partnership with several local authorities and organizations. This is, in part, what makes the West Branch such a great choice for fly fishing. There are trout ranging from 10-17 inches on average, and it’s one of the most beautiful streams in the region. 

This is a freestone and tailwater stream, offering a selection of brown trout and brook trout that are part-wild and part-stocked to ensure maximum catch potential for anglers. This is a complex stream consisting of slow-flowing sections, pool/riffle configurations, and even a technical “lake” at the lower end of the river by the dam at Wilmington. Fishing in this section isn’t favorable due to the deep waters, but the rest of the river has plenty of potential.

Best Places to Fish the West Branch Ausable River

The West Branch Ausable River begins where South Meadow and March brooks merge as they flow from Mount March. It crosses Route 86 early on, and agave the bridge is great for slow to moderate waters that coast through the meadows. Below the bridge, it gets a little quicker and you’ll see more of the pool, run, riffle stream style that you expect in this region with a five-mile catch-and-release section that’s popular. 

Below the Wilmington Notch, you will come to the 100-foot high waterfall known as High Falls. Then, the river settles again with some pools and small waters before hitting Flume Falls, which has another pocket of fast action before settling down closer to the Wilmington Dam. You can generally find good fish anywhere that the water is flowing slower, but the actual “lake” area might prove too deep for good fishing.

Those who want the ideal fly fishing conditions will head to the tailwaters below the dam, which often looks more like a freestone stream in some places. With plenty of pocket water and large boulders, this is a good area if you can get to it. There’s also a good section near the Ausable Forks dam right before the river merges with the East Branch.

Best Time to Fish the West Branch Ausable River

During the fall months, the water gets a bit cold but fish are still biting. There are midges and BWOs hatching that attract plenty of catches and people fare well when using leeches and sculpin during these seasons. The best time to fish West Branch Ausable River is during May and June, but the summer months will offer great fishing for most of the season, as well. 

The Green Drake hatch, along with sulphurs and tricos, come in the summer and those are what attract the best catches. The winter is usually too cold in the large river for good catches, but you may be able to find larger trout with imitation midge larvae and pupae. If you go during the warmer months, the deeper areas will be best for fishing. 

In the fall and winter months, many opt for the shallower waters that may have warmer temps and attract the trout coming from the cold pockets on their search for a better spot. Usually, access won’t be impeded by weather or seasons, although the river can get a bit high in the spring and fall months.

Stream Flow and Current Conditions

Be sure to check the stream conditions before heading out to fish the West Branch Ausable River. The USGS stream gauge near Au Sable Forks, NY provide a good indication of current conditions.

The graph below shows the stream flow (discharge) for the past 7-days. If flows are considerably above or below historical norms (yellow triangles on the chart) then fishing conditions maybe not be ideal.
