Shortly downstream from the dam powerhouse rapid starts. The river narrows and pushes up against the left bank. The gradient is rather steep over large boulders creating a lot of turbulence with several holes to avoid. Scout from river right.
An easy rapid the starts just above the Maplewood bridge. At the tail end of the rapid is a chute formed by a large rock on river right. The main flow at low to medium water levels pushes over a pourover in the middle of the chute. The pourover is easily avoided by catching the eddy behind the rock on river right. From here a jet ferry will carry you above the pourover into an eddy on river left. This eddy affords great access to a series of nice surfable standing waves just below the pourover.
After a long section of quickwater and class I the river approaches Alderbrook rapids. To recognize the start of Alderbrook look for a gray box like house on river right at a class II rapid. Note, in LesselÂs New England Whitewater guide this house is said to be pink, it has not doubt been painted since that writing. The rapid is not easy to describe so scouting is recommended, it generally requires a boater to start on river left move to river right then back left. Scouting is easiest from river left; portaging is easiest from river right.
USGS gauge located just upstream from the put in on river left. The Ammonoosuc starts high up on Mt Washington (6288') and runs later in the season than most other White Mountain rivers. Forecast Late April

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.
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.
American Whitewater and Merrimack Valley Paddlers have reached an agreement to purchase a 10-acre parcel fronting on Contoocook River in Henniker, NH. The land serves as an important launch point for whitewater paddlers enjoying the popular section of the river that runs from Hillsborough to Henniker. This section of the Contoocook River contains rapids ranging in difficulty from Class II to Class IV.
