River Description

The West Fork Tuckasegee Gorge is currently a wild and beautiful, but woody place. Hike in on the incredible trail built by Duke Energy that starts in a well-signed parking lot just across the dam from Highway 107. Don't get lured into putting on before the trail ends at the base of the massive double drop known as High Falls or Cullowhee Falls. Put on too soon and you could risk going over one of two big unrunnable drops.  

At the put in, amidst the spray and wind coming off High Falls, you will have a choice: Either paddle across the river and hike around the first two challenging Class IV/V rapids, or run them. Note that the entire run below the put in is private property.  After the two entry rapids (and some wood) the river mellows and flows through small rapids until a house comes into view on river left, and an obvious horizon line appears. Pick your way center through a couple entry slides and then you come to the hallmark drop of the run, a 25 foot slide typically run well left of center. Note that at least two people have suffered significant back injuries on this slide, and scouting is extremely difficult. 

Small rapids (and strainers) continue until you come to two houses right on the stream bank on river left. The homeowners of both of these homes are very concerned about trespassing, so please be respectful. These mark the location of a man-made relatively new rapid. It offers a nice 4 foot boof just a couple feet off the left bank. There is a rock in the landing but a good boof should make for a soft enough landing.  If you scout this drop, stay in the streambed and respect private property. Just past this rapid there is currently a large tree across the flow. You can portage either direction but catching a small eddy river right will be the easiest route and keeps you further from the homeowners.

The river continues at this Class II/III pace for a ways. You will see a small house on the right just above the river. Just after this house, the river will drop over a series of slides. These aren't as steep or tall as the earlier big slide, but quite a bit of fun.  You can catch a small eddy on river right above the first one to scout.  he first of these slides (Kornegay's Cascade) is the biggest, probably 15-20 feet of total drop. The river right side is currently no good with trees in the runout.  The preferred current line starts left of center and moves right down the slide to the bottom. The other slides are smaller and easy to scout from your boat.

These slides will continue until you pass under Cullowhee Forest Bridge (a private road with no public access), at which point the river changes character dramatically. A nice slide indicates you are almost to High Turnover, the crux of the run. High Turnover boasts a lead in wave/hole followed by a vertical ledge hole, followed by a sloping ledgehole that can dish out some surfs at the right flow. More cool bedrock rapids continue for a while as the river flows through a small mini-gorge before the run opens up. Once it opens up it stays pretty mellow to the takout at the bridge near the Tuckasegee Powerhouse.   

The West Fork offers paddlers a couple of complex boulder garden Class IV/V rapids at the put-in, a big slide, several smaller slides, a standout class IV mini-gorge, and many other class III rapids. Be aware that this entire run below the put in flows through private property - travel respectfully. 

Put in: Drive across the spillway and dam to a wide turnout – parking area on the right at the west edge of the dam. The recommended put in is downstream of High Falls, about 8/10 of a mile below the dam, at the terminus of the well marked trail.  DO NOT PUT IN ABOVE HIGH FALLS.  

Take out:  There is a parking area on Hwy 107 next to the powerhouse. The shuttle is 7 miles exactly. Duke Power has built a walkway from the takeout bridge to the parking area.

Rescue Protocol:  Someone who is injured and needs to be assisted off the river from the private land needs to call the Glenville Rescue Squad at 828.743.3655. They will come in with access to the private land gates (Cullowhee Forest has multiple gates, not just the one at Hwy 107) and remove and/or transport an injured paddler to care.

Release History: On June 29, 2001, American Whitewater organized a team of volunteers to run this dewatered reach as part of a whitewater flow study. We found a super fun creek run of moderate difficulty with one big drop and tons of great low angle slides and boulder rapids. We signed a settlement agreement with Duke Power and other stakeholders in 2003 recommending 7 annual releases, which were expected to begin in 2006.  Delays associated with the removal of Dillsboro Dam have prevented the new releases from becoming a reality. FERC licenses were issued in 2011, and 2013 became the magic year when releases began.

Gauge and Flow: A very useful stick gauge is located across Hwy 107 from Thorpe Powerhouse. It is located underneath the upstream side of the metal bridge, bolted to a boulder next to the bridge's foundation on river-right and facing downstream. The gauge measures level in feet and tenths of a foot. Much of the river feels like class III with a few class IVs when the water is bouncing between 2.6ft and 3ft on the stick. The river's class IV rapids remain class IV down to 2.4ft or even 2.2ft. However, 2.4ft makes the river's class II/III slides very scrapey, and turns its class III rapids into mostly class II+. Running the harder stretches is not advised for typical class III boaters when water is hitting 3ft on the gauge.  The first two rapids of the class IV mini gorge (The Crux and Center Boof) are frightening at 3ft and higher.  However, the last two rapids (which merge into one at 3ft) are stiff but manageable class IV as high as 3.3ft, and the Two Mile Runout is a class III+ romp at 3.3ft. Scheduled releases are intended to be 250cfs, which corresponds to water bouncing between 2.4ft and 2.6ft on the stick gauge across from Thorpe Powerhouse

Duke Energy links messages about unscheduled and scheduled releases into the WFT gorge on its "Nantahala Lake Levels" page (http://www.duke-energy.com/lakes/nantahala/nantahala-lake-levels.asp). Just look in the last column of Lake Glenville's row. If there's a date, click it to open a page that has announcements about releases from the lake into the WFT gorge.

Two web pages can be used together for a usually reliable "online" way to know if there's water in the WFT gorge:
  b. Duke Energy's Power Generation Schedule on EFT and WFT:
There is probably water in the WFT gorge if *any one* of the four following conditions is met.
  1. At least 250cfs at the SR1172 gauge (link "a" above) AND *no* power generation on the WFT or EFT (link "b" above).
  2. At least 500cfs at the SR1172 gauge (link "a" above) AND power generation on the WFT but not on the EFT (link "b" above).
  3. At least 750cfs at the SR1172 gauge (link "a" above) AND power generation on the EFT but not on the WFT (link "b" above).
  4. At least 1000cfs or more at the SR1172 gauge (link "a" above) AND power generation on both forks (link "b" above).
These "rules-of-thumb" are based on three facts:
   1) Power generation on WFT through the Thorpe Diversion Pipe adds around 250cfs at the SR 1172 gauge.
   2) Power generation on EFT through Cedar Cliff's powerhouse adds around 500cfs at the SR 1172 gauge.
   3) Releases through Thorpe Dam's gate are typically close to 250cfs.
Two glitches in these "rules-of-thumb" I can think of are 1) the rare circumstance when Duke opens Cedar Cliff Dam's flood gate, adding more water to EFT than the electricity-generating release, and 2) when Duke reports releases into WFT (link B) that aren't through the Thorpe Diversion Pipe.

Kevin Colburn's story about the flow study pdf.  Note that the second flow referred to in this story as "350cfs" was determined later to have actually been 250cfs.  This optimal flow will be the one provided by releases starting in 2013.

Rapid Descriptions

Thorpe Dam (Class N/A, Mile -0.8)

Launching immediately below the dam is not recommended because of the major waterfalls downstream.

First Falls (Class VI, Mile -0.2)

Mandatory Portage!  This falls can be portaged with difficulty on either side, but the river left side may be easier.  On the left, climb down next to the falls and jump the last bit into a pool at the base.

High Falls (Class VI, Mile -0.1)

High Falls on the WF Tuck

High Falls on the WF Tuck

Mandatory Portage!  This waterfall has two tiers and is about 170 to 200 feet high.  The river right side is blocked by high cliffs, but there is a use trail on river left which facilitates the portage.


Put In below High Falls (Class IV)

West Fork Tuck put-in

West Fork Tuck put-in

This is the recommended put in because it avoids two very difficult portages. A parking area is located about 0.25 mile after crossing the dam's spillway. The trail to the put-in begins with a gravel road and then becomes a trail with log steps and boulder steps down to a put-in that is sprayed with water comming off High Falls.

Put in below High Falls. To walk the put-in rapid, ferry across the river to the big eddy and the river right trail. A long class IV rapid begins immediately after the put-in. At levels higher than the normal release, the two rapids merge into one.

First Boulder Garden (aka, Debris Field) (Class IV, Mile 0.1)


Photo by Matt J. (top) and unknown (bottom) taken 04/08/18 @ 0 cfs

A small pool on river-right separates the put-in rapid from the first boulder garden.  This second rapid is roughly 100 yards long. The first half can be run river-left or center. The last half is run river-right.  One should scout river-left before putting on if running the left line because trees tend to accumulate a few feet downstream of the first drop.  Trees also accumulate in the center line, but they're usually obvious from the upstream pool.

Second Boulder Garden (Class IV, Mile 0.2)


Photo by clipped from Boyd Ruppelt's video (https://www.youtube.com/watch?v=M1-mHq90j0Q) taken 06/04/16

A shallow-angle slide and perhaps 30 yards of class II+ water separates the first boulder garden from the second boulder garden. Take the right channel, which will lead to two back-to-back boulder drops on the right channel's left side (visible in the photo above) immediately followed by 20+ meters of a fast, bedrock rapid (not visible in the photo).

Trailside Stretch (Class III, Mile 0.3)

A little over a mile of class II water along with two or three class III rapids follow the second boulder garden.  The first class III rapid after the second boulder garden  passes a pretty waterfall on river-left formed by Rough Run Creek.  It is private property and posted as such with signs and steel cables.

A trail on river-right is never far from the river until the river-right bank steepens and rises 50 feet or so above the river.  The trail is on private land, but public access by foot is generously permitted with posted restrictions (no fires, no camping, no hunting, etc.).  Signs near the trailhead on Shoal Creek Mountain Road specify the restricted activites.

Lead-in Ledges to Breakbone Falls (Class III, Mile 1.3)

The first horizon-line you see about the time a house comes into view on river-left is *not* Breakbone Falls (aka, Flight Simulator). It's a 10ish foot high ledge on river-left or a fun, fast curving slide on river-right.  You can see the horizon of Breakbone about 100 yards downstream from the base of this first lead-in ledge. There are two more sloping ledges upstream of the falls. Both have eddies in the center, left, and right.

Breakbone Falls (aka, Flight Simulator) (Class IV+, Mile 1.4)


Photo by Ben Peters, Chris Mriscin, Crystal Gustin taken 06/08/18

Leland Davis, the first known to run the right line, informally called this falls "the Big One" in his guide to western NC creeks and rivers.  The river's local sage, Burt Kornegay, has long called it Breakbone Falls, an apt name given the fact that it fractured vertebrae of two people who were carried out on backboards during the first year of official releases.  See http://www.americanwhitewater.org/content/Article/view/articleid/31911 for identification of the line where inujuries have occurred.

The river-left line (known to some as Crash Landing) is a 28 foot, broken, rough slide into a large pool.  Enter far left over the center of a small wave on the horizon line.  Being too far right on the small wave results in a ride with two or three very hard hits. Being too far left can result in hitting a bedrock slab about one-third of the way down.

The river-right line (commonly called Flight Simulator, but also called Fright Stimulator or Go Right and Fly by others) is about 25 feet high.  It starts with a 6.5 foot sloping ledge if you're far enough right, but it'll start with a pothole that's 7 feet deep and 12 feet wide if you're too far left. The sloping ledge ends with a 4.5 foot drop followed by a 14 foot vertical drop. Beware pitoning at the top or at the bottom if too far left. Pitoning in the top pothole can result in a beating, either in the pothole or on the way down the remaining 20ish feet.

Thanks, Burt and Harrison, for making the measurements.

One more word about back injuries.  The big bounce on the river-left line that has caused back injuries is located near the bottom a bit right of the ideal left line.   Photo 1 and photo 2 show boats on the big bounce.  Paddlers who  lean forward over the bounce have had far smoother lines than those sitting up or boofing.  Check out this photo taken at base flow to understand the landing zone.

Residential Stretch (Class III, Mile 1.6)

A few class II+/III slides and ledges form the runout of Breakbone Falls and lead to a right bend that is soon followed by three houses and a stretch of class II bouldery water.  The river bends right again after this stretch and offers a 3 to 5 foot river-left boof in the bend.  Several class II+ ledges and a couple class III ledges (some bouldery, others bedrock) and small slides follow.

Kornegay's Cascade (Class III+, Mile 2.7)


Photo by clipped from Boyd Ruppelt's video (https://www.youtube.com/watch?v=M1-mHq90j0Q) taken 06/04/16

Shortly after passing a house on river-right, there'll be a horizon line that marks this 20ish foot, medium-angle cascade. Run it pretty much anywhere, but most run it center and just a smidge left of center for the most fun.  Do not get too far left or you may dry out on your way down.  There is a medium-small hole midway down the center-left line.  There are two medium-small holes near the bottom of the center line.  There's a ledge hole at the bottom of both lines, but it has been friendly at the normal release level.  A medium size sloping ledge with a moderately stronge hole on river-left and then some fun slides follow Kornegay's Cascade for about 0.1 mile.

This cascade is visible from the guard rail of the hairpin curve on Hwy 107 known as Cabbage Curve.  However, the property along side the road is private and posted.

Cullowhee Forest Bridge (Class III, Mile 2.8)


Photo taken 05/08/12

After going under Cullowhee Forest Bridge, head right over wet bedrock. Stay right to boof the left side of a 5 foot ledge. Alternatively, head over to the left bank for a steep 10ish foot slide that hides between the bank and a large boulder.

The next rapid is 30 yards or less away.  It's a sloping ledge that has a left-to-right crease in the bedrock. Some run right to left. Others run it pointing straight downstream.

The photo above shows the third rapid after the bridge. This shallow slide can be run about anywhere. The photo was taken when the level was much lower than the normal release level. The ledges visible in the photo are padded to the point of being pretty much indistinguishable during a scheduled release, but the slide is still shallow.

A left bend after the slide signals the lead-in to the mini gorge.

Mini Gorge (general description) (Class IV, Mile 3.0)

People who participated in the 2001 flow study identified a collection of four rapids as the "mini-gorge."  The number of back-enders and flips they experienced in the first rapid of the mini-gorge led them to collectively name the rapid High Turnover.  This first rapid, which is also called The Crux and Burt's Beasts by some people, is indeed "the crux" of the mini-gorge.  It is distinct from the mini-gorge's other three rapids, and it is separated from them by a pool and another 50 yards or so of class II water:  The rapids downstream of High Turnover include two back-to-back (but distinct) ledges followed by a long, tight, fast, bedrock rapid with small ledges and strong swirls. These three rapids become one, long rapid when the level rises above 3 feet on the gauge at the take-out bridge  Each is identified separately with individual descirptions for clarity.

Mini Gorge's First Rapid: High Turnover (aka, The Crux) (Class IV, Mile 3.0)


Photo taken 08/22/15 @ 2.70 ft

The mini gorge's High Turnover can be scouted river-right.

The first half of High Turnover consists of a steep, sloping ledge that feeds into a sneaky, speed-trap hole. The speed-trap hole is followed by a benign-looking, 2ish foot high, river-wide ledge. The speed-trap causes many people to get stuck in this benign-looking ledge. If stuck, most people are able to work themselves out on river-right (surfer's left).

The second half of High Turnover consist of a notch (left) or a boulder boof/drop (center) followed by a smooth, bedrock, shallow-angled slide into a stompy hole that has a strong, horizontal recirculation coming off the river-left, bowl-shaped wall. The hole is strongest on river-left. If stuck, work your way out of on river-right (surfer's left).

Mini Gorge's Second Rapid: Center Boof (Class III+, Mile 3.1)


Photo taken 05/08/12

A pool follows High Turnover.  The river splits 50 feet downstream of the pool.  The left channel is usually blocked with wood. The river-right channel is shallow and cluttered with suitcase-size rocks that want to force you farther right, which is bad.  Regardless of which channel you take, get to the center as you round the island because you want to hit the center launch pad of the ledge that follows. There is real potential for a vertical pin in the right corner of this ledge.

The photo was taken when flow was WAY LOWER than the normal release level.

Be aware that the this ledge changes its nature when level exceeds 3ft on the gauge at the take-out bridge.  The center pad becomes a pour-over into a very large, boiling, recirculating hole.

Mini Gorge's Third Rapid: Crevice Ledge (aka, Lumpy Ledge) (Class IV, Mile 3.1)


Photo of Crevice Ledge by Burt Kornegay taken 06/08/13 @ 2.60 ft

Typically run far right. At normal release levels, there are two river-right eddies and a river-left eddy between Center Boof and Crevice Ledge.  Some people run it exactly as shown in the photo, boofing into the crevice.  Others run far right. One an also run it far, far left (shoulder agains bank). Running it left or center is abusive.

The photo shows that the mini-gorge's 3rd rapid and its 4th rapid can be considered a single, long rapid even at 2.6ft.  They truly merge into one long rapid when the level nears or exceeds 3ft.

Mini Gorge's Fourth Rapid: Swirly Gneiss (aka, Smooth Granite) (Class III+, Mile 3.2)


Photo of Swirly Gneiss by Burt Kornegay taken 06/08/13 @ 2.60 ft

Coming off Crevice Ledge river-right or center-right will feed directly into this last rapid of the mini gorge.  A tongue of fast green water sweeps down right-to-left before rising and piling up on the river-left wall.  The water then swirls for a couple hundred feet over smooth, gneiss bedrock with three small (~3ft) ledges under a smooth-face cliff.  The swirling water, fun waves, smooth bedrock, and sheer cliff create the sense of being in a miniature, less difficult version of Tallulah's Amphitheater.  Although usually pure fun, you should be watching for wood in this very narrow, fast, swirling stretch.

Photo shows paddler dropping into the top of this fourth and last rapid of the mini gorge.

Two Mile Runout (Class II+, Mile 3.3)

A mix of class II and III water with several wave-trains and small slides.

Thorpe Powerhouse - Take Out (Class II, Mile 5.5)

The take-out is across Hwy 107 from Thorpe Powerhouse on the downstream, river-right side of a metal bridge.  It is clearly identified with a sign as the take-out.  The official stick gauge is located on river-right under the bridge, bolted to a boulder near the bridge's foundation.  For release weekends, expect designated parking areas for paddlers.

The takeout stick gauge was showing 2.5~ft. for the 250 CFS release on 8-10-13 . At that time I
found folks asking when it would start to release. Don't let view fool you, it does look low, so
check the gauge. Also new long tree down across the run very shortly below the little bridge.
Approach with caution and go center-left and forget the top eddie on right . At This Time, the tree
is still green leafed and help up by it's branches for now. We ducked under it fine , this time.

Hiked down the trail to the put-in today. Starts out as a dirt road then a well constructed trail
starts on the right as the dirt road continues left. The well - constructed trail continues for a
short distance, ending in a clearing with a bunch of trees that have been cut. The dirt road comes
back in and continues for a couple of hundred feet, then turns into an unimproved (narrow, muddy,
slick) trail. This continues past the first waterfall that is huge. The trail continues, eventually
dropping below a set of cliffs near the top of the second waterfall. The trail then turns into a
scramble among rocks, logs, and trees down the hillside until it is nearly even with the bottom of
the first of the two drops in the second falls (huge, lands on rocks). The trail (if you can call
it that at this point) continues down amongst the large rocks, logs, and trees into a large patch
of rhododendron until it meets the river at the bottom of the second drop of the second falls. It
was a difficult hike without a boat. With a boat it would be best to use a rope to lower the boat
down to someone waiting below in stages. It will take a LOT of work to turn the current scramble
into a trail walkable with boats.

Ran this yesterday (just happened to catch it- don't know the flow, so I might be overestimating
what the river will be like at release and my comments below might be overinflated) and have to
make some comments:

this is a creek, so if you don't have skills to run stuff like the North Fork French Broad, Lower
Big Creek, or similar stuff, you will find this a little big for your taste. The reason I say this
is based upon the number of holes (some pretty sticky), the amount of trees, and the overall
difficulty of a couple of rapids. One rapid in particular, located about 1/3 to 1/2 mile below the
bridge at Cullowhee Forest development is a Class IV/IV+ (maybe a V at high water) due to the two
holes in the rapid, and an undercut I noticed. It has 3 or 4 moves in it, and drops into a pretty
nasty hole on the bottom left. Be careful and be good at boat scouting if you've never run this,
you'll be in boogie water alot in some sections.

Overall, I think it is going to be a gem of a run (the water was crystal clear)- we just need to
get some strainers moved out of there.
