River Description

The Boreas River is a classic Northcountry river.
Just below the route 28N bridge put-in, the water flows peacefully though a boreal forest. The pace picks up, and suddenly you find yourself in a challenging zig-zag rapid (IV) which constricts into an exit hydrologic. Immediately downstream is a waterfall (V), which can be scouted (and/or carried) on the right.
Minor rapids lead into a substantial section of flatwater. Just when you're beginning to wonder when it will end, the riverbed tilts downward. Get ready, because the next several miles has some of the most continuous creeking rapids (IV) in the Adirondacks. When you reach the North Woods Club Road bridge, you can take-out here, or continue another mile of rapids (II) to the Hudson River.

If you're not into the continuous set of Class IV rapids, you might be interested in the Upper Boreas.

Rapid Descriptions

Entrance Exam

Class - IV Mile - 0.5
Rapid Thumbnail Missing

After an initial warm-up of gently moving water, the river turns sharply left and tilts downhill. Class III/IV whitewater has an eddy on the lower left; you may want to catch this eddy and scout around the next bend. The river turns sharply to the right, narrows, and ends in a hole which can usually be punched through. The waterfall is several hundred yards downstream.


Class - 5.0 Mile - 1
Rapid Thumbnail Missing

This is about a 10 foot waterfall. It is vertical on the right and sloping in the center. It is a double drop on the extreme left, next to the undercut wall.

Guts & Glory

Class - N/A Mile - 4
Rapid Thumbnail Missing

After several miles of flatwater, the river tilts noticably downward. After about a mile of class III fun, there is a large eddy on river left. You may want to catch the eddy and catch your breath; this is where the nonstop class IV action begins. The river is steeper and twisting from here to the Northwoods Club bridge. Swimming is to be avoided.

   The name was originally coined by Dennis Squires, who wrote a whitewater guidebook and perished on a river in New Zealand.


Gage Descriptions

The bridge over the Boreas river on the Northwoods Club road features a hand-painted gage (thanks, Pierre). It is on river right, on the downstream side on the bridge.

The gauge minimum is based on a rough approximation from Dennis Squires' book; it should not be used as a definitive guide for whether or not the river is runnable or not.
