River Description


The Mad has a relatively short season due to its small and steep watershed. When it is running this is one of the longest stretches of continuous class III-IV whitewater in the state. Be cautious of rain or warm days in the spring when you are at the put-in. The river can rise up from low to too high by the time you reach the gage 6 miles down river. On one occasion in May of 1994, a group put on in a light rain. The rain along with snowmelt from higher elevations of the watershed raised the river to a ragging torrent about 4 miles into the trip. Many boats, and paddles were flushed downstream as their occupants were rescued and found their way out. Most of this group took off at this point.

Take a left at the Waterville Valley ski area access road.
1/4 mile take a right by the gas station/country store (Mountain Petroleum).
Drive up to the recycling area just past the store.
The put-in is down a steep bank on the left.
There are other possible put-ins upstream from this point, chech a map for other alternatives.
 

Take out

Rapid Descriptions

Map of the Mid Pemi region

Class - Mile - 0

Ho Hum

Class - IV Mile - 2
Class II and III rapids will be continuous until NH route 49 becomes visible for a short distance on your left. Once the river turns away from the roadway a sharp drop will be visible in the distance. Take out river left and scout the best line. Normally you would start from river left then move your way into the eddies behind a couple large boulders midstream. From this point you can peel out towards river right through a couple big holes at the bottom. In low water this drop can be full of pinning rocks. Even in high water large rocks can throw you off your line.

Landslide falls

Class - IV Mile - 5
Once again this drop is out of site from NH 49. As you approach Welch Mtn on your right class III water leads up to a short pool. Look for a sudden drop in the river up ahead, a rock slide will be visible just to the right of the drop. Pull out on river left and scout. There are two possible routes, going to the right of the large boulder midstream will drop you vertically 3'to 4' into a fairly large hole. Going to the left of the boulder forces you to make a sharp right turn into a wierd hole. Where the river takes a sharp right the water piles up against a rock creating a pillow. Use the pillow to drop you into and through the wierd hole/whirlpool below. At low water there is not much of a pillow and the wierd hole is just a series of smaller holes.

Smarts Brook Rapid

Class - IV Mile - 7.2
Once you pass the Upper Mad river road bridge the river calms down from continous class III to class II+. 1/4 mile from the bridge Smarts Brook enters on the left, NH route 49 will be visible straight ahead with a distinct drop before the road. Use a zig zag manuever starting from river right, move left, then river right once more around immense boulders. The turbulance in this section can be considerable in medium and high water.

Gage Descriptions

Note: The gauge refered to in this section is a virtual "regional" gauge. It is in a nearby watershed but the proximity of the gauge and the river characteristics are similar. These gauges work best in the spring or wide area rain events. Do not rely on this gauge for localized rain events such as summertime thunderstorm activity. Current minimum run level for this stretch is still to be verified (see table below). There is a hand painted gage on a rock at six mile bridge (Upper Mad river road). It is located on river left just under the upstream edge of the bridge.
 

Level      Painted gauge    USGS EB gauge (CFS)
Minimum         1.3           830
Scratchy       <1.6	       1200
Low            <1.8           1530
Low to medium  <2.1	       2060
Medium         <2.5           2870
Mdium high     <2.8           3600
High           >2.8
Too high......>above gage rock


Estimated chance (%) of finding the river runnable.
Month............% chance.................comment
 

January ............ 0%....Frozen. 
February.............0%....Frozen. 
March...............10%....usually Frozen. 
April...............35%....Best chance in late April
May ................25%....Best chance in early May. 
June.................5%
July.................3% 
August...............3%....Just a trickle
September............3%....Lowest water month 
October........�.....8%
November............20%....Fall rains, dormant trees 
December............20%....River starts freezing early in month. 


Be aware this is averaged out over several years. The % chance refers to the probability of finding the river running on any given day. For instance a 3% probability for September means on average you can only expect 1 day of water. One year there could be 2 days in September with water, other years none. Spring levels are usually higher than fall levels. The river rises and falls rapidly because of the small steep watershed. An occasional summer storm could bring the river up for a couple hours.

Building a "Virtual" gauge for the Mad
In the table below visual observations have been matched with actual USGS gauge readings from the East Branch USGS. This is an attempt to build a Virtual gauge for the Mad. Virtual gauges work best during spring runoff and widespread rain events but should not be relied upon for localized rain events such as thunderstorm activity. Once enough observations have been matched with the USGS gauge readings, we will determine which USGS gauge readings best matches the Mad river's runoff profile.

Protecting Access to New Hampshire Rivers

11/3/2016
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

6/2/2015
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.

AW, MVP Protect Land and Access on the Contoocook River (NH)

6/18/2013
Robert Nasdor

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.
