River Description

The Middle Swift is a very good intermediate run. This section of the Swift is sandwiched between two class V drops that can easily be by-passed. The rapids in between are a lot mellower mainly class III. The biggest drop in this section is Triple Drop; it is two 3' drops about 50' apart with a big wave/hole at the bottom. At lower water Triple drop should be considered class III+. A look at the take-out for this section is advised since you don't want to run Lower Falls without scouting.
The Swift runs along side the scenic Kancamaugus Highway in the White Mountain National Forest. It is not wild but still scenic, the road and tourist areas at the put in and take out can be crowded with curious people taking pictures or just gawking especially late in the Spring. Note: the above mentioned gradient information does not include Upper and Lower Falls. See also the Upper and Lower Swift.

Put in

From Interstate 93.
Interstate 93 to exit 32. State route 112 (Kancamaugus Highway) east for approximately 24 miles.
Approximately 3 miles pass Bear notch road look for the pull off for Rocky Gorge Scenic area.
From NH route 16.
Take a left on NH route 112 (Kancamaugus Highway), head west for approximately 9 miles to Rocky Gorge Scenic area.
The put-in is down a steep bank on river right just downstream from the foot bridge. Caution: do not put in at the parking lot.
Parking may be difficult in April due to snow and the bathroom facilities may be locked and unavailable.

Take out

Head east towards Conway on the Kancamaugus Highway for 2.8 miles.
Take a left at the next tourist/scenic/picnic area signed Lower Falls.
Parking here should not be a problem in April due to snow because it is partially plowed but the bathroom facilities here may also be locked and unavailable.
Note: At the put-in and take out it will be necessary to have a White Mountain National Forest parking sticker. These can be purchased at the information center just off exit 32 on Interstate 93 on the west end of rt 112 (Kancamaugus Highway). Or at the National Forest Service information center at the intersection of NH routes 112 and 16 on the east end of the Kancamagus highway. It is also possible to buy a day pass from the self service kiosk at the Lower Falls recreation area.

Rapid Descriptions

Upper Falls

Class - 5.0 Mile - 0
Rapid Thumbnail Missing
Upper Falls is located in a tourist area called Rocky Gorge. From the parking lot at the put in class II-III water leads up to a 15' falls into a small box canyon. If you are running the upper section along with this section make sure you scout this area carefully. Pull out well upstream once the river starts dropping over small ledges with sticky holes. Carry around below the tourist foot bridge for an easy put in on river right or a 10' seal launch from either side of the box canyon. Should you choose to run the falls the usual line is from river right over a 45 degree slide to the 10' verticle drop below. Keep the nose of your boat up on the slide to keep from pitoning off protruding ledges at low water levels.

Triple Drop

Class - III+ Mile - 1.8
The biggest drop in this section, not including the put in or take out rapids, is Triple Drop; it is three 2' to 3' drops about 50' apart with a big wave/hole at the bottom. When the Kancamaugus highway disappears and is replaced with a high cliff wall on your right, make your way to river left just above the first drop and scout your line through the holes at each drop.

Lower Falls

Class - 5.0 Mile - 3.5
Rapid Thumbnail Missing
When picnic tables and tourist with sneakers and cameras appear on river right takeout and scout Lower Falls. The river gradually picks up pace and difficulty as one heads down through the entrance rapid. Lower falls is a series of 6' to 8' ledges that run parallel to the river from the center with the ledges dropping off from left to right. You must scout this drop. It is necessary to run a route through a series of blind drops. A far left route leads the paddler over a more gradual slide. But the approach requires you to punch two large stickey holes. The slide itself contains numerous holes and boulders along its path. The other route (the usual one) requires a precise drop over the 8' ledge between a boulder and some shallow water. Take a sharp left after this drop paddle hard to launch over the next ledge over a stickey hole at the bottom of the drop. Below lies a fairly large calm pool for an esier put in for the lower section.

Ran the Middle Swift today at 0.85 ft. Great run, starts scratchy and I would say that it requires Class III technical skills to avoid a potential pin. We cleared a strainer and the whole river is quite clear, assuming new high water does not pull something into the river. The low level does leave a nasty piton rock exposed on a drop too difficult to identify in a comment, just use caution. I love this run, how it starts slow and really picks up about half way and then never stops. The run takes about 1 to 1 1/2 hours, depending on how much you pause on the river. Like the guide says, pay attention at the end or you will end up unwittingly running Lower Falls.

Ran it on 10/22/11 at about .7 ft. This is well below what AW says is minimum, but I though it was a great level. We did shorten the run on both ends though. This was my first run, so I can not say what changed after Irene. Other members of the group said the changes were minimal. All the rapids were fine.

Has anyone run Rocky Gorge? The story about that gal in '49 or whenever it was that got sucked in that underwater cave gave me second thoughts, if anyone has please post best route (straight through on river left or snaking through a little to the right). Thanks!

Gage Descriptions

The gauge is painted on the gorge wall (also known as Cabin gorge) in the Lower Section; you have to stop along the Kancamagus to look at it. It is located about 1 mile below the Albany covered bridge. Look for cabins across the river as the river drops below the view from the road; park carefully along the narrow shoulder and look up against the cliff on river left.
3/4' .....minimum scratchy level
1.75......Low to medium
3' .......very high
Estimated chance (%) of finding the river runnable.

In the summer of 2009 a new USGS gage was installed on the river right bank just downstream of the visual gage.  We are still in the process of correlating this new gage.

Month............% chance.................comment

January ............. 0%....frozen. 
March.................5%....Usually frozen.
April................65%....Best chance mid to late April
May .................35%....Best chance in early May. 
August................3%....Just a trickle 
September.............8%....Tropical storms and their remains 
November.............30%....Fall rains, dormant trees 
December.............20%....River starts freezing early to mid 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 August means on average you can only expect 1 day of water. One year there could be 2 days in August with water, other years none. Spring levels are usually higher than fall levels. The headwaters contain a mix of mostly steep mountainous terrain but also some small lakes and swamps in the watershed just above this section. These tend to buffer the flows somewhat allowing a more gradual rise and fall than other rivers in the White Mountains. Spring levels are more dependable due to snowmelt at the higher elevations. An occasional summer storm could bring the river up for a day.

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.
