River Description

Big South Fork of the Cumberland is one of the hidden crown jewels of the Cumberland Plateau in East Tennessee. Formed by New River and Clear Fork near Oneida, Tennessee, this class II-IV run offers a big water adventure through a cliff lined gorge that is accessible only at a few points. Bring a playboat, river-runner, canoe, or raft. This run is truly a wilderness whitewater adventure.

The rock structure is typical Cumberland plateau sandstone, which locals know and love, but which can be unnerving for visitors to the area.  Beware of deep undercuts and sieves and treat every rock as if it had water underneath it until proven otherwise.

There are only a few (3?) actual class IV rapids, but they are classic and fun at a wide range of flows.  There are also some very long pools, so go prepared to paddle your way across the flats, or spend a very very long time waiting for the wind to blow you there.

For those who don't want to run the class IV's, it's possible to put in at O&W and join for just the bottom couple of miles of the run.  There's some great surfing in the O&W area.

Put-ins and Take-outs

There are several take-outs and put-ins for the Big South Fork. The run documented on this site is from the confluence of New River and Clear Fork to Leatherwood Ford. It is 6.2 miles in length and will take 2 to 4 hours (or longer) to complete.

The main take-out is at Leatherwood Ford where heated changing/restrooms are available. This is the most accessible take-out on this run with paved roads all the way. There is one additional take-out at the O&W Railroad Bridge. This take-out eliminates the last 2 miles of the run, which consists entirely of flat water with two class II rapids. If you put-in at the Confluence and take-out at the O&W Railroad Bridge, the run is only 4.2 miles and takes about 1 1/2 hours to complete. This run consists of almost all the class III and IV rapids on the entire Big South Fork. The O&W road is in much better shape now than in years past. In the spring of 2004, the Scott County Road Department graded, graveled, and ditched the road. Since that time, it has developed several potholes but is still in descent shape for a Scott County back road.

Confluence to Leatherwood Ford Shuttle Information
From Leatherwood Ford take SR 297 east for approximately 7 miles. You'll come to Coopertown Road. Make a right and go approximately 4 miles. Turn right on Verdun Road. Go 1.2 miles and make a right on US Hwy 27. Go 1.2 miles and make a right at the airport sign (formerly a Subway existed here). Cross the railroad and take a left on Detour Rd. Go 1 mile and make a right on Airport Road. You'll then go 1 mile where John Long Road will veer left by some oil tanks. Stay on John Long Road till it ends at the Confluence put-in parking lot. This road is 4.8 miles in length.

O&W Railroad Bridge Access
The O&W Railroad Bridge can be accessed from Verdun Road. About halfway between SR 297 and US Hwy 27 on Verdun Road is the Edgewood Estates entrance. This is where O&W Road begins in a sharp curve. The bridge is approximately 8.6 miles.  The easiest access is upstream from the bridge on river right.

The Canyon Section Run
Two miles upstream from the O&W Railroad Bridge is the Pine Creek put-in. You'll know the put-in by the gated road that drops off beside O&W Road. This put-in is just above Maria's Rock which is the start of the Canyon Section. This playable two-mile section offers big wave trains at around 3,000cfs and is great for those who don't want to run the entire Big South Fork section. Multiple runs on this section can be fun, fun, fun!

Rapid Descriptions

Google Map of Big South Fork

Class - Mile - 0

The Confluence

Class - Mile - 0.01
Rapid Thumbnail Missing
New River and Clear Fork meet at the confluence to form the Big South Fork. Access to the confluence is by hiking 1/4 mile down a trail from a parking lot at the end of John Long Road.

Confluence Rapid

Class - II+ Mile - 0.02
Confluence Rapid is the first rapid which is basically read and run.

Undercut Rock Rapid

Class - III Mile - 0.2
Rapid Thumbnail Missing
This rapid, sometimes refered to as Diagonal Wave, has a nasty undercut rock on river left. The standard line is right of center, then drive back toward center.

Triple Wave/Boof Rapid

Class - III Mile - 0.4

Boofing opportunities exist at this rapid. Simply line up left of center and BOOF!! The other line is run from right to left through 3 waves.

Big Rock

Class - II Mile - 0.6
Rapid Thumbnail Missing
Most run this class II rapid down the left bank. Just read and run.

First Drop of Double Drop

Class - III+ Mile - 0.8

Double Drop is the first of three rapids known as "The Big Three". The main line is on river right with a series of two drops. Catch an eddy on river right above the first drop then ferry across and drop off beside a rock on the left side. This will land you in a boiling eddy where you will then paddle aggresively down the center to run the second drop with a little left angle.

The alternate Double Drop line is extremely far river left. This line is a class II read and run line that lands in a large eddy.
One of the better play spots is located just above this rapid. It is a low-angled, fluffy hole that is great for today's short boats.

Second Drop of Double Drop

Class - III+ Mile - 0.81

You must paddle aggresively at levels below 1000 cfs due to a pin rock that sits about two feet of the right bank. The second drop will surf you into the rock where water will pile up on your stern. Then, you are jambed into the crack stern down. Several paddlers have gotten pinned vertically in this spot.




Washing Machine

Class - III Mile - 0.9

Washing Machine is known for it's twisting and sticky action at levels below 1000 cfs. It's a 10ft wide chute that drops into a twisting hole. An alternate route can be cheated on river left over a small ledge. However, this ledge can develop into a nasty hydraulic above 1,500 cfs. At levels above 1000cfs, the sticky hole in the main line disappears and the rapid is simply run from left to right.

The Ell

Class - IV Mile - 1

The Ell is the last rapid of "The Big Three". Start from an eddy on river right to boat scout this one. Look for a rock on river left where the river curls from left to right. This marks the final drop and is where you want to aim. Drive hard toward this rock a little left of center while the river tries to pull you to the right. Then, get ready for a ninety degree turn to the right for the final drop. If you flip in this one, tuck hard at levels below 2000cfs due to "Cheese Grater Rock" being only a few feet or less underwater immediately downstream. The center and right side of the final drop is a large hole that can be sticky.

Oh Sh*t

Class - III Mile - 1.2
Rapid Thumbnail Missing
This rapid is run on river left down a chute. Start left of center, then drive back right.
At flows above 8,500 cfs, this rapid turns into a river wide terminal hole of death.

Honey Creek Rapid/Kreckels

Class - III Mile - 1.6
Honey Creek rapid offers something for everybody. It starts with a play spot, continues with a wave train and holes, and then finishes with a couple of sieves.
Work your way down the left bank to find an awesome play hole. Just downstream, the river bends to the right where a long, wave train begins. Enter the wave train in the center then drive left into a large eddy to avoid "Punch in the Nose" which can be a monster wave hole. Next, ferry out of the eddy into the last half of the wave train to run the final drop right of center. Then drive back left across boiling eddies and swirls.
Just above Honey Creek Rapid on river left is an access point. The trail will take you straight up the side of the gorge to the Honey Creek Overlook.
CAUTION: The last drop at the end of the wave train includes a rock, just left of center, that has a sieve under it. A boater once bumped into the upstream side and was sucked under to resurface on the downstream side. Additionally, there are multiple sieves in and around the large river right rocks after this drop. I know of at least one boat that has been eaten by these sieves.
The last part of Honey Creek Rapid creates a terminal hole above 9,000cfs.

Hand of God Rock

Class - I Mile - 1.8

You'll have to look upstream to see this rock. It makes you wonder who might have created the Big South Fork gorge.

There's a cave under this rock that you can paddle through at 400cfs.

Rion's Eddy/A*s Kicker

Class - III+ Mile - 2.2
The standard line is left of center. Go too far left and you'll land in an eddy that can be difficult to get out of. Run too far right and you'll find a hole that's caught many boaters. A river right eddy makes boat scouting easy.

Canyon Section

Class - III+ Mile - 3
Maria�s Rock is a large rock in the center of the river, which marks the start of the Canyon Section also known as The Narrows. The Canyon Section consists of mostly fun wave trains and a few surfing waves.
Just upstream, there is an access point from O&W Road at Pine Creek that is popular for those who are camped at the O&W railroad bridge and are only running the Canyon Section.

The Sieve

Class - III Mile - 3.3
You don't want to wash into this sieve. It's usually jammed with trees and whatever else happens to float by. Run this rapid on river left by riding the tongue from left to right between two holes. A river right chute appears to be runable but also ends in a sieve.
This rapid turns into a terminal hole at 10,000cfs.

Jake's Ledge Hole

Class - III+ Mile - 3.4
Jake's Ledge Hole is a riverwide ledge that has two options for running. At flows below 1,500cfs, you can run the boof line which is far left about 2 feet off the left bank. This line will land you in an eddy but, at higher flows it turns into a terminal hydraulic. I saw a boat recirculated for 15 minutes here one day. It has also been said that the left wall is undercut.
The other line is on river right beside an undercut rock. Just line up left of the rock and paddle straight through.

Canyon Rapid a.k.a. Moonshoot

Class - III Mile - 3.5
Canyon Rapid starts with two holes and ends with three waves known as "The Three Sisters". You'll run this one down the center on a tonge that will twist you between the two holes. Next, continue down the center through "The Three Sisters". This is where you'll find eddy service on the right for wave surfing action.

Deliverance Rapid

Class - III Mile - 4.1
Rapid Thumbnail Missing
After a long pool, which is the original Jake’s Hole, is a sharp bend. This is the start of Deliverance Rapid. Simply go down the center and enjoy the waves.
This rapid got its name back in the day when commercial rafting was on the Big South Fork. When the rafts would come around the bend, a local would streak the customers and run.

O&W Rapid

Class - III Mile - 4.3
This rapid, located under the O&W Railroad Bridge, consists of several waves including one large one. Run this one straight down the middle.
The O&W Railroad Bridge can be used as a take-out thus, eliminating the last 2 miles of flat water. There are also several camp sites at both ends of this bridge.

Leatherwood Ford Take-Out

Class - Mile - 6.2
Rapid Thumbnail Missing
After an awesome run on one of the plateau's best rivers, you will find that the twin bridges at Leatherwood Ford is a welcome site to see.

Ran the BSF three times this spring and couldn't count the number of tires in the beaches. This run is in dire need of a river cleanup.

Paddled this 3/12/17 level was ~9.5ft. or ~3500 cfs a bit pushy with chaotic waves and many boils. I portaged almost every major rapid. I enjoyed the flow at ~950 cfs or ~6.5 ft. much better 2 weeks prior. It was a beautiful sunny day didn't see anyone else on the river. Put in near burnt mill bridge maybe 1 mile downstream along the trail. overall was still an excellent day on the water would have ran more rapids but was running solo. Hiked in from Leatherwood ford day prior, John Muir trail, excellent hike as well.

4/5/15, 2400 cfs, overcast skies but highs in the 60's. G, Adam, Robert, Chris, Eli and CT. We mixed it up with the maxi me, the new grabner tandem inflatable canoe and the spanish fly. The grabner did great on the bigger water and ran pretty dry over the big waves. We all ran the left side of double drop, and Adam and Eli ran multiple laps on the El while we ate lunch. This is a great level for cleaning up some of the scrapey rocks and the holes arnt that stompy yet. No swims just smiles.

On Thursday we launched from Burnt Mill Bridge to Leatherwood. A mixed group, from Canada eh? , of canoes and me in my kayak. Half of the group stopped at the Confluence and hiked out to the car parked on the road past the Scott County Airport. The kayak and two open BlackFly canoes went on downstream. Matching post for Clear Fork section exists. Level was about 1800cfs which was lower than what I usually see on this section (2000-3000cfs more typical for me in the past). We enjoyed the heated changing-room at the takout, but noted the set of stairs leading from the high-water line at O&W Bridge as a possible takeout in the future to avoid the 2 miles from OWB to Leatherwood Ford. From the confluence it's approx 3/4 mile to the first of the big three and that 3/4s mile is mostly straight. When the river first starts to turn back to the left, below the Confluence, is where Double Drop is getting close. Scout from river right. We had more room for the larger canoes in a higher eddy rather than the eddy that I normally scout from in my kayak. The first drop was fine, center or slightly right of center into the boiling funny-water before the second drop. We ran the second drop angled towards the massive boulder pointing our bows river-left to square-up to the curler wave coming off of the boulder. One canoe flipped and we separated swimmer from boat in the pool to keep him away from what appears to be a sieve just downstream. Washing Machine gave us no trouble. Scouted the El from a taller, large boulder in an eddy upstream and then also walked downstream on river left to get a better look at the curler on river left side of the maw of the hole. Boat-scouted the rest of the river. Decent surfing waves for my Nomad8.5 in and below The Narrows.

Sep 1st 2014 The river was running at 1,050 CFS with a time on the river close to 4 hours. The water crafts where 2 Spanish Fly's, Mamba, Mini Me and the Maxi Me. Great day full of sunshine. We had Eli, Crisler, and Golder as our Guides/safety's and G, Steve, Chris, John Christen and I as the crew. G ran the river great in his Canoe, switching out on just a few rapids that Golder and I ran. Steve started out great, than had a few trips and lost his composure, letting Crisler paddled the Mamba the remainder of the river. I flipped the Spanish Fly on a rapid a few down below the Ell.

7/1/12 Leatherwood Ford the Canyon Section. Water was running at 625cfs and was really nice to see how much the river changes with less than 300cfs drop. George and Simon with Eli as our guide. We ran the Probe 12 and the Detonator. Gerge had another perfect run without any falls on the Probe 12 and Simon fell 2 times on the Detonator. Water was low but still great on a canoe, almost better without as much pushing water and more rocks to man over around. Great day learning how to paddle a canoe.

Ok South Fork regulars. Let's see if you can add to this list of sieves on the run.... New

Forum: BoaterTalk
Date: Dec 30 2003, 2:14 GMT
From: hardboater

1. Center, top drop of Double Drop - water slides into an undercut which actually sieves out due to sitting cocked funny on a slab rock.

2. River right side of the pool between Double Drop and Washing Machine.

3. The recently learned of top left of the Kreckles.

4. Bottom right of the Kreckles - water sieves out a crack in the bottom right side of a really boily/swirley room with an eddy harsh fence blocking exit.

5. Bottom left wall of Ass Kicker - 3/4 of the way down

6. The obvious one that everyone knows about in river center about 1/3 of the way through the Canyon - always has wood jammed in it....

7, 8, & 9. The far river right of #6. The river drops into a box canyon and filters out through sieves on the right, left and underneath.

10. Right above the big river right eddy 1/3 of the way through the rapid above O&W (the longest rapid on the run). Water filters through a slot too small for a boat and into the eddy.

11. Far river left at the very top of O&W.

Crazy how many sieves there are on this class III-IV run. And this post doesnt even touch on the undercuts......

This was my first time down the canyon and..... words cannot describe the wow factor. Emerald green water and the orange sandstone cliffs - sweeet. I guess we caught it @ 1400 a really nice level with lots of play spots - watch out surfing the shallow pour overs/waves. Really nice ender hole about halfway down and one MACH 3 killer surfing wave.

Had a few guys from knoxville with and worked the jackson crew in their tight little behinds. Flow was around 370-350 for the day. Got to see a boat getting worked for a moment in washing machine. When i went through the drop i went under and then poped up below. Pretty sweet to make my way under the suface in the BLUNT. Even for such a long drive and little water it turned out to be a great day on the water. Rapids were still fun and there were tons of slots to play around with. If ya haven't done it its worth it for the fact that its so beautiful in there. Can't wait until a good flow so i can take my squirt boat. It looks to be like a great place to tap into.

I paddled BSF on 7/23/2005 at about 1300cfs. Washing Machine was truly what it's called, a "Washing Machine." The entrance to the Ell was a lot pushier and fun. Moonshoot was the best surfing spot on the whole river. I had forgotten how much fun BSF can be at low water.

The BSF gorge and canyon sections are runnable at least as low as 350 cfs at Leatherwood. I haven't tried to go any lower, but they're still fun at that level.

the pin spot is located at the second drop, it is a large seive with a pin spot.
the pin is in play below about 1000 CFS and gets worse as the water level gets lower.
I posted two pics (taken by Wilko) of a boater in the pin spot river right at the second drop. The Boater did not paddle thru the hole at the second drop of this rapid, was stern squirted and then surfed into the pin.
this is the way the pin typically happens. I have pulled three of my friends from this spot and observed two other pins in this same location.

I believe running the second drop on the right is much safer than running the hole. another option is to run far channel left, but is more difficult than running right, from the squirrelly water between the drops.

it is difficult to get out of your boat in the eddy beside the pin spot. if you are going to set safety, hike down from the top of the rapid, or make sure ppl wait until u have time to run the rapid and get out of your boat. the eddy is deep and squirrelly.

My favorite levels are from 700 to 1200 cfs (technical verticle drops; watch out for Ryan's Eddy) and between 3500 and 4500 cfs (continuous big waves; Honey Creek rapids and Pine Creek CAnyon Yippee!).

Gage Descriptions

Much of the flow for BSF comes from New River which drains the Cumberland Mountains north of Oak Ridge and Clinton, Tennessee. When hard rains hit that area, look for BSF to be running the next day.

When running shuttle to the Leatherwood Ford take-out, there is an electronic gage in the gazebo that you can checkout for the latest flow information.

Several of the rapids get more difficult at levels below 1,000 cfs such as Double Drop, Washing Machine, The Ell, and others while large wave-trains form at around 3,000 cfs.
This run has even been paddled at levels above 10,000 cfs. I know of one group who ran it at around 50,000 cfs. Just remember that the river changes character considerably at these higher levels and a swim could potentially be long and very dangerous.
