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 So

The Confluence

Distance: 0.01 mi

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+Distance: 0.02 mi
Rapid
Confluence Rapid

Confluence Rapid is the first rapid which is basically read and run.

Undercut Rock Rapid

Class: IIIDistance: 0.2 mi
Hazard

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: IIIDistance: 0.4 mi
Hazard
Triple Wave/Boof Rapid

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: IIDistance: 0.6 mi
Rapid

Most run this class II rapid down the left bank. Just read and run.

First Drop of Double Drop

Class: III+Distance: 0.8 mi
Hazard
Waterfall / Large Drop
First Drop of Double Drop

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+Distance: 0.81 mi
Hazard
Second Drop of Double Drop

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: IIIDistance: 0.9 mi
Rapid
Washing Machine

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: IVDistance: 1 mi
The Ell

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: IIIDistance: 1.2 mi
Rapid

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: IIIDistance: 1.6 mi
Access Point
Hazard
Honey Creek Rapid/Kreckels

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: IDistance: 1.8 mi
Rapid
Hand of God Rock

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+Distance: 2.2 mi
Rapid
Rion's Eddy/A*s Kicker

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+Distance: 3 mi
Access Point
Canyon Section

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: IIIDistance: 3.3 mi
Hazard
The Sieve

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+Distance: 3.4 mi
Hazard
Jake's Ledge Hole

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: IIIDistance: 3.5 mi
Canyon Rapid a.k.a. Moonshoot

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: IIIDistance: 4.1 mi
Rapid

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: IIIDistance: 4.3 mi
Access Point
O&W Rapid

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.

River access points are shut down. My friend and I tried to run from confluence to Leatherwood Ford today and parking area is off limits. Had planned on running it around 860 or so cfs in a shredder but were unable to secure safe and secure access without harassment. We ended up speaking with an LE officer with the BSFNRRA who equated it to being like wally world on National Lampoons Vacation. Neither one of us found it too funny the river being off limits. In any event river access closed until further notice. I'm not sure how to do this on here through AW but Simon Krzych I'm interested in speaking to you if you dont mind. Several river related questions. Please reach me at wsteel15@gmail.com. Thanks again everyone. Hope to see you on the river.

We paddled to the O&W bridge with a canoe and two rafts on April 5th, 2020. The level was 1910 and the water was a beautiful bluish-green. 1910 feels pushy, but is a great level. The O&W road was crowded, but we did not see anyone else on the water.

If you've ever wondered what Double Drop looks like at minimum flow, this is it. Somewhere around 400cfs.

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.
