River Description

The East Branch of the Pemigewasset is a natural flow river best run in late April and May with the snowmelt from the high peaks of the White Mountains.

The river gets its start in the mountainous federally designated wilderness area upstream from the put-in. As a result the water is clean, clear, and usually cold when the river is running. Don't be fooled if the water looks too low; local river lore states that if it looks like there's enough water then it's probably too much!!!

This river is a classic New England run. Continuous whitewater, a few more difficult rapids, and lots of technical moves required. Many boaters consider this river one of the best regularly run rivers in New England.

With the exception of a few bigger rapids on either side of Loon Mountain, the entire run is similar in character. (Although some purists claim that the upper section, reachable only by walking upstream is the best.) The river is relatively wide (85') for a New England river. It is strewn with car (and larger) sized boulders. These boulders create extreme turbulence during high water. The rapids are continuous and at high water all blend all together for a long class IV-V run. Any swim at high levels may result in the loss of one's boat as it is quickly swept many miles downstream. Be aware because of the nature of this river, boulders (even large ones) move and shift every spring changing the river character.

The Upper East Branch of the Pemigewasset run starts below Franconia Falls at the confluence of Franconia Brook and the North Fork of the Pemigewasset. To reach it you must walk/carry/drag your boat up the Wilderness Trail three miles along the river. The upper section is a bit more technical and unforgiving then the lower sections. Additionally the riverbed is more wide open, requiring a bit more water to paddle.

If a long walk just to paddle a beautiful river doesn't appeal to you, then start your run (as most do) on the middle section o

Another boulder strewn stairstep rapid. This rapid is just downstream from a large Mack truck sized boulder next to the first home you come up to on river right.

Culvert

Class: IVDistance: 4.9 mi
Rapid

After passing a series of condos on your left, the river splits around an island, at low levels the left channel is too scratchy to be much fun. The right channel is narrow (25 feet) but steep. Many holes force the paddler to dart around the narrow channel. Just before the river joins up with its other half you will notice the remains of a dam on river right. There are also two large culvets in the river bed that must be avoided. Be aware fo another culvert downstream in the middle of the channel, as of September 2001, the openning of this culvert was facing downstream but high water could once again turn this culvert into a more dangerous position.

Upper Loon Rapid

Class: IVDistance: 5.1 mi
Rapid
Upper Loon Rapid

Just before reaching Loon Mountain Ski Area, and shortly after the end of Culvert Rapid in a longish, pushy, technical rapid.  The river is wide open here and there are multiple channels and routes.  The huge number of large boulders and holes require constant maneuvering.  This is the longest difficult stretch on the river.  Go left at the bottom and take out to scout Loon Mountain Rapid.

Loon Mtn. Rapid

Hazard
Loon Mtn. Rapid

Update: Post-Hurricane Irene this is a different rapid. The upper section is easier; at the bottom the left is more technical and pushy.  [Prior description: At the bridge to Loon Mountain ski area, the river drops over the most difficult rapid on the Pemi. This rapid has changed over the past several years, a flood in 1994 undermined the bridge abutments. The bridge abutments were repaired and the riverbed was filled with blasted rock just downstream of the abutments. This changed the rapid considerably leaving no good channel to run until the river scoured out a couple of channels over the past few years. The far left channel is easiest; it starts just past the bridge and is mostly a clean stair step drop onto the head of a rock island that splits the river. At this point you can maneuver to river right and complete the drop through a myriad of sharp pinning boulders that require lots of maneuvering or you can stay in the river left channel at higher water levels for an easier run. The right channel at the top of the rapid is more difficult because of the precise lines required to run it successfully. The usual route threads a pushy course along the left side of the channel bouncing thru some big waves. At higher water you can also thread your way down a narrow chute towards the right side of the channel. Scout this rapid carefully before you run.]

The river drops over the rubble left over from a dilapidated dam. There only seem to be boulders and some concrete in this drop but be aware that there could be rebar or spikes. Holes and pinning rocks are the greatest hazard here. Post-Hurricane Irene Update: This rapid is now more technical and difficult, especially at the bottom.

Mill Dam

Portage
Hazard
Mill Dam

Once you view the USGS gauging building on your right, take out on river left on a gravel beach and scout the next drop. The rapid funnels through a cut in the log cribbing of an old delapitated dam then slides over a smooth ledge with two river wide hydraulics. At low water the upper hydraulic is worse, while at high water the lower one is. These hydraulics can hold boats and boaters for sometime and most people choose to walk around this rapid. There is a sneak route on the far left and another just to the left of the holes. The far left requires a paddler to scrape over ledge halfway down if the water is medium or lower. The usual route would be to run the tightrope just left of the holes and right of the shallow ledge. You can easily get off line here and end up in one of the holes.

South Mountain Rapid

Class: IVDistance: 7.4 mi

After Mill dam the river widens and can be a little scratchy at low levels. Most of the water in the river then channels to the left and is only about 25' wide at this point. Rapids pick up to the South Mountain bridge crossing. After the bridge the river drops over a constricted boulder pile that requires precise manuevering. At the base of the drop a nice series of surfing waves form with a convinient eddy on river left at medium levels.

Good view of this rapid from the I-93 bridges.  At medium or high levels the waves can get quite big here due to the large gradient.

This was a fun level, requiring some scouting in places where the drops are steep enough to prevent a good boat scout. The culvert has washed up into the right bank below the island just above Upper Loon Rapids. Upper Loon had the most technical and sustained rapid finishing with several drops, some into stout holes, just upstream of the bridge. Took a barely-in sneak line past the old dams at 'Old Hole' behind Gordi's steakhouse and didn't have to carry. Very fun run to teach and practice good scouting!

Great run today with 6 paddlers new to the EBP, 6 miles from Lincoln Woods trailhead to the Fire Station in Woodstock.  Total run with a few stops took 5 hours.  Perfect intro level to learn the demands of this river character as it is not too pushy.  The flip side is that there are half a dozen locations where the river widens and water gets thin requiring a few shoves over rocky shoals. 600 cfs would likely be more fluid over the entire range and still a good intro for new paddlers to Class 3/4 rivers.  800 cfs definitely ramps up to more forceful conditions that require faster reaction times.  At 400 cfs, LOON RAPID was easy to scout and discuss on river right.  We set safety and all who chose to paddle through had no trouble on the typical route of bobbling into the upper pool on river left, then darting across the current diagonally toward river right, aiming for the largest boulder, which creates a smooth line just past the hole on river left-center in the last drop.  This river never lets up!  The rapids are consistent with steep gradients and many holes and boulders to navigate, with many rapids ending in an unavoidable flushing hole.  Only one significant STRAINER at this location tag, a half-mile before Mill Rapid.  44.050704, -71.651645   It is easily seen and does not cover the whole river with a 10-ft bypass on far river right.

There is a river wide strainer just as the I93 bridge comes into view. It's right below a rapid and around a curve so you can't really see it until you are in the rapid. My best guess of coordinates based on looking on Google maps after the fact: 44.034664,-71.674087

From longtime AW member Jim Sindelar:

I ran this yesterday (4/20/06).

The level during my run was just under 1 foot on the Kank. Bridge boaters gage. The rapids were definitely 'white,' not green flowing water. I would call it a delightful and exciting level on the low side of 'medium,' definitely not a scratchy low water run. Thus the meaning of the gage has continued to evolve and now seems to be back to the early days of the first gage when 1 foot meant a good medium level.

The strainer identified in the river left drop by the island requiring a portage in 2004 is no longer a problem. The trunk of the tree is still there, but has settled into the river deeply enough that with good control, a clear run is available.

The upper put-in is reached after a two-and-a-half hour (three mile) trek up a trail or road along the river.

This section of the river, located approximately 3/4 of a mile from the put-in, shows the typical character of the upper East Branch.

The Upper East Branch begins at the confluence of Franconia Brook and the North Fork of the Pemigewasset. There are old trails/roads along both sides of the river.

The eighth major drop on the Upper East Branch is currently blocked by a strainer requiring a portage or drag around.
