Summer Recreational Releases

The Pontook releases every weekend from Memorial day weekend through two weekends following Labor Day.  Releases start at 10 am and conclude at 4pm


Erroll NH...Gateway town

Errol NH located in northern NH close to the Maine border offers a wide range boating opportunities all summer long. This area offers some of the most remote regions in the eastern US. Wildlife is plentiful and may include Moose, bear, Loons, Bald Eagles etc. In addition Lake Umbagog located just north of Errol is a federally protected National Wildlife Refuge .
The Errol rapid located on the east side of Errol is a short class II section good for training and novices. Saco Bound (Northern Waters) has set up a small outfit here on the western shore with a campground, paddling school, and small boating shop. Water is controlled by a hydro dam just upstream from the campground and runs through this section every summer day. This section is onlabout 1/3 of a mile long and boaters usually carry back upstream and run it several times a day.
The Pontook section of the Androscoggin is about 15 miles south of Errol on route 16. This section offers a longer and more interesting class II run. Pontook dam releases most weekends.
Starting in late June and ending in late August, the Magalloway and Rapid rivers offer more challenging boating.
The Magalloway located 20 miles north of Errol in Wilson Mills Maine, offers class III and V boating on the upper stretch. Releases are on weekends starting in late June through the second week in July. The Rapid then has four release weekends until the middle of August then once again the Magalloway finishes up the month of August with weekend releases.
The Rapid River offers class IV boating in a remote setting. The Rapid can only be reached via a maze of logging roads just outside of Upton Maine about 10 miles east of Errol.

Rapid Descriptions

Dam View rapids

Class - II Mile - 0.2
Rapid Thumbnail Missing
The put in is located at Pontook dam. There is good access here with parking, picnic tables and bathrooms. Carry down just below the dam and put in here. During a release the tailrace from the dam can create some very large and powerfull waves. Downstream from here class I and II rapids over a very wide river bed are the norm.

Road View rapids

Class - II Mile - 1
Just as the road comes into view are the most difficult rapids on this river segment. Very large waves and some holes on river left. At the end of this segment the river slacks off a bit until you reach Powerline.


Class - II Mile - 1.3
Rapid Thumbnail Missing
Easy class II rapid with some play on the waves.


Class - II Mile - 1.9
Rapid Thumbnail Missing
The last rapid on the Pontook. Good waves and holes sprinkled about. River left provides the most sport. River right tends to be shallow. Once you reach Wheeler pool just below the bypass dam the rapids are over for this section. Paddle downstream around a small island then take out on river right at the Bowfinger public canoe access.

(Originally reported May 27, 2018) There is a 20 foot log near the beginning of the Pontook put in. The log like tree trunk is in river center and very difficult to see until you are on top of it. A raft was stuck and got off after much effort. We were upstream and did not realize the raft was on a log and assumed a rock. We should have been more careful. One of our kayaker was pinned to the trunk. Luckily the trunk moved after he took off his spray skirt and his boat filled with water. Both him and the boat flushed under the trunk. A young man from the raft was able to move the trunk a little so it is more visible and at more of an angle. I believe that they hope to go back and remove the trunk once the water level dropped. Thank you to the people on the raft for helping us in this difficult situation. [Edited by Streamkeeper.]

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.
