Fishing Recommendations

The Great Chazy River in Northeastern New York is one of the Adirondack region’s most underrated gems. Flowing from the mountains near Lyon Mountain down to the flats of Lake Champlain, it offers a "tale of two rivers": a classic cold-water trout fishery in its upper reaches and a world-class smallmouth bass fishery as it nears the lake.

As your guide, here is the comprehensive breakdown for fishing the Great Chazy.


🎣 Location Overview

The Great Chazy River is characterized by its diversity. In the upper stretches around Ellenburg and Mooers, you’ll find classic Adirondack pocket water, tumbling riffles, and deep, cool pools carved into the bedrock. This is prime trout territory.

As the river flows east toward the town of Champlain, the gradient levels out, the water warms slightly, and the habitat shifts toward large boulders, submerged logs, and slower glides. This lower section is a Smallmouth Bass paradise. The river is special because it lacks the heavy "tourist" pressure of the nearby Ausable, offering a more solitary experience with highly productive water.

💡 Pro Tips & Local Knowledge

  1. The Mooers "Transition Zone": The stretch of river near the village of Mooers is where the trout and bass water overlaps. On a good June day, it is entirely possible to catch a 16-inch Brown Trout and a 3-lb Smallmouth in the same pool.
  2. Match the Crayfish: The Chazy has a massive population of rusty crayfish. If you aren't sure what to throw for bass, use a heavy-beaded streamer in a "burnt orange" or "olive brown" color and bounce it along the bottom.
  3. Watch the Gauge: The Chazy is a "flashy" river, meaning it rises and falls quickly after rain. Check the USGS gauge at Perry Mills. If the flow is spiking, stick to the edges with large, dark streamers.
  4. Stealth Matters: In the upper trout sections, the water can get very clear. Long leaders (9-12 feet) and a stealthy approach (don't splash!) are required for the larger holdover Browns.
