River Description



The description here is from the put in along state route 302 about two miles west from the intersection of state route 3 in Twin Mountain.  Look for a convenient riverside pull off.  Alternatively, you can access the river close to the route 3 intersection and run the upper part.  This adds 2 to 3 miles of class I-II river good for a warm up before encountering the continuous class II and III waters below. 

The river starts with typical boulder strewn class II  then builds up to a more difficult class III- drop called Boat Breaker just half a mile upstream of the take out at Pierce bridge. 

Most of the river is secluded and out of site of the road with tall northern spruce along the banks.  There are occasional camps along the way.

Post Irene update. Carl F and I ran this section on Monday Oct 2nd at 4.07 ft on the gage. The run is currently clear of strainers and debris. We had an enjoyable run. Lots of surf and technical eddy hopping. Enjoy, Steve Jacques, Bartlett, NH

Protecting Access to New Hampshire Rivers

2016-11-03 13:30:00-04

Northeast boaters can celebrate that another beloved whitewater gem has been protected. Paddlers on the Winnipeseaukee River are now assured that the put-in on the Lower Winni in Northfield, NH will be forever protected thanks to the donation of a parcel from Gloria Blais in memory of her husband Roger. Gloria donated the land to the Town of Northfield for the purpose of assuring that future generations of boaters will have access to the river. Protecting river access to the Winni is part of an ongoing effort by AW in the northeast region to protect river access.

Bellows Falls (VT) Flow Study Reveals Hidden Whitewater

2015-06-02 15:57:00-04
Robert Nasdor

A hardy group of northeast boaters climbed into the natural river channel below a hydropower dam to participate in a flow study designed to assess whether whitewater flows should be restored to this dewatered river reach on the Connecticut River. While significant obstacles remain, this site has the potential for providing instruction, playboating, and a big water feature that that could be run throughout much of the year and provide a much needed boost to the local economy.
