River Description

Smarts Brook put in is a 1.5 mile hike up a cross-county/mountain bike trail to the put in. Put in at the bridge over the river linking the Smarts Brook and Yellow Jacket trails. The first mile has several class IV ledge drops with easy class II-III water in between. When the river takes a sharp left and enters a shear wall gorge, take out and scout. The gorge is approximately 1/4 mile long with many steep constricted drops. Access is difficult because of the shear walls. Logs also are a problem often blocking the only route through. Take out at the Smarts Brook trail access parking lot or continue into the Mad river and takeout at the "Eddy" two miles downstream.




Flow Information

There is no gauge on this river. Smarts Brook runs only during high water runoff in spring, usually late April or May. Watch out for ice in the shaded gorge. The correlation gauge is an estimate. If you run this section please leave a comment with more flow beta.

Protecting Access to New Hampshire Rivers

Robert Nasdor

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

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.
