River Description

River description.
There is a small parking area at the put-in near Ayers Island dam. There is a porta poty located here along with trash cans. Additional parking can be found at the top of the dam where a hiking trail leads down to the put-in parking lot.
The river is about 1-1/2 miles long with three distinct play spots. The first big drop is about 1/4 mile downstream with a medium size sidesurfing hole (Rodeo Hole)it is not for novices to play in. Run right at this point. Downstream 100 yards there is a good surfing wave depending on level. The river from this point to the take out is mostly small rapids with a few oppertunities for surfing a sidesurfing. The last rapid is a series of reactionary waves and holes caused by protruding ledges on a long sweeping right turn. The last ledge at the take out is probably one of the best summer time play spots in NH with a great sunning and spectating rock to go with it. Depending on level it is either a sidesurfing hole, surfing wave, and or ender spot.
You can takeout at the Pemi Park & Play or just slightly downstream at a ledge. This take-out is easier for canoes and rafts. It also leads up to a small parking area on Coolidge Woods road which has new porta poties maintained by Public Service company of NH.

Mapquest Directions

From Concord, NH 

 

Directions from southern NH.


Interstate 93 north to exit 23.
Left on state rt. 104 (west) towards Bristol.
Approximately 4.5 miles, look for a baseball field on the left.
There will be a yellow playground sign just before you get there.
Take a left here and go around the ball field towards the recycling
center.
Drive past the entrance to the town garage, sewage treatment
facility, and recycling center. The road at this point turns to a
rough dirt road descending steeply to the small parking area at the
base of the dam. Note new handicap accessible outhouse.
 

Directions to the take out:
As of the Fall of 2009 a new bridge opened to replace the metal truss bridge that used to cross the river from Bristol to New Hampton.  This cuts the shuttle down to 2 miles from the 8 miles we had to endure over the last couple years.

Head back out to NH rt 104 and take a left toward Bristol.

In the center of town at the intersection of rt 3a take a left then another immediate left in the town square.

Take the right (downhill) at the fork. 

Follow the road down over the bridge then take a right on Coolidge Woods road (dirt).

Approximately 1/3 mile to take out. Look for vehicles parked at the
play spot. Or take out a little further down stream where the river
flattens out. 


 

New put in access

In the summer of 2006 a new river access path was put in by PSNH. It is accessed from the same parking area. The path leads a short distance downstream from the old put in. The path is made up of crushed stone and has an even grade all the way to river level. This is a great improvement over the continually shifting rock jumble we used to put in at.
 

Osprey cam

In 2003 Public Service Company of New Hampshire installed an artificial osprey nest at their Ayers Island hydro facility. Since that time a nesting pair of Ospreys have taken up residents to raise their chicks for the last few years. This Nest is visable from the putin. Look to the river left side of the dam to view the telephone pole platform with a large nest on top. In the summer of 2006 PSNH installed a webcam so we can view the nest at anytime.
