On January 26, 2024, American Whitewater purchased a large portion of the classic Lower Big Sandy river landscape. Located in northern West Virginia, the land includes 4.25 miles of river frontage spanning almost the entire river left side of the gorge, the remainder of which is already under conservation [...]Read More
Run Description
The Big Sandy is becoming more popular every year as the jewel of the Cheat River watershed, the largest undammed watershed east of the Mississippi. The run includes two waterfalls--Wonder Falls and the more challenging Big Splat--along with several technical class IV rapids. Big Splat is an AW Standard Rated Rapid with a difficulty of 5.1 when the Rockville Gauge reads 6.1.
Big Sandy starts with some big ledgy rapids and then morphs into a boulder garden run. The ledge above Wonder Falls can be tricky above 6.5' as a large hole awaits at the bottom left. This can be snuck right. The 18 foot Wonder Falls is next with multiple line possibilities at different flows. Ledges continue at Undercut rapid, Little Splat, and the Infamous Big Splat. Big Splat has a tricky entrance, the flow exiting the rapid pushes hard right (not the direction you want to be heading). Big Splat is run right to left avoiding the Splat Boulder at the base. Portage or seal launch on the left. The run below switches to boulder garden rapids with short pools in between. First and Second Islands are the standout rapids and might warrant a scout or check for wood. The run ends at the Cheat River confluence.
At higher water levels (> 6' at Rockville), it's often fun to run the Upper Big Sandy or the Little Sandy before the Lower. This gives a longer run including good play and scenery, and it gives those who don't want to tackle the Lower a good opportunity to enjoy the Sandy without fear. You'll find a nice surfing wave at the Rockville put-in, and a great view of the beautiful Sovern Run Falls.

After a mile of mostly Class-3 ledgy stuff, with some good play, the paddler comes to Wonder Falls. This 18-footer, which follows a mildly complex set of offset diagonal holes, is one of the more photogenic rapids around, and it's easier than most falls of its height. Warning: at higher water, 6.5' or so, it sneers viciously at the off-line paddler, with a hydraulic that will multiply recirculate the unfortunate swimmer. Those who want to run it a second, third, or seventh time carry back up on river left, a short hike through the omnipresent rhododendrons. One paddling friend found a can of beer there once, which made the foot attainment doubly worthwhile!
There are Highwater lines on river left that can be run. Above 7' tuck in behind the boulder on the left. At 8'+ you can run against the left bank.

Wonder Falls is followed by rapids that are typical of the character of the Sandy: continuous Class-3 boogie water. About a half mile along comes Undercut Rock, which lives up to its name only for those who choose to run it on the right. That line requires a strong punch of the hole that surfs the paddler into the rock. However, it's an easy ledge-drop for those who run it to the left of the rock.
Undercut Rock is the lead-in to the most intense section of the Sandy, beginning with Zoom Flume. Though this rapid can be run on the left, as AW safety guru Charlie Walbridge does, most boaters choose to take on a complex series of holes and diagonal waves just above a cheese-grater slide. This is where people tend to break paddles just out of the shrinkwrap, or put a grapefruit-sized hole in the shoulder of the article of clothing formerly known as 'drysuit.' Those who flip in Zoom Flume tend to favor one shoulder or elbow when they go to work the following Monday. Don't ask me how I know. See another good Zoom Flume pic by clicking here.
A short pool is abruptly punctuated by Little Splat. Not as notorious as its big brother, Little Splat can still pack a punch for the unwary. It's a long, technical rapid with a bad pinning rock at the end. My line begins at the far, far left, avoiding a ledge-hole that's grabbier than it looks. I then head for an eddy in the middle left before working my way to the far left again. Whatever you do, be sure to end up left of the pinning rock at the bottom (just to the river right of the paddler in the picture).
One short pool beyond Little Splat is the Biggie. There's no shame in walking Big Splat, a 15-footer in which all of the flow wants you to land on a bad piton rock. The line at the main drop is tough to read from water level. As if that weren't enough, the approach is gnarly, with undercuts and a bad keeper hole. This reporter once found himself upside-down through the horseshoe hole in the approach and barely rolled up in time for the main drop, an experience I never wish to repeat! Splat certainly lives up to its 5.1 AW rating. The portage is on river right, where a rope is attached to help you get down the ledgy drop.
Some first-timers walk around the gnarly approach to Splat and simply run the final drop.
Whether you walk or run Splat, it's a good idea to turn around and look back upstream. The view of the rocks, trees, and the travertine green water is something to treasure. It's part of why so many of us have fallen in love with the Big Sandy.
After Big Splat is some more of the Class-3 boogie water that makes the Sandy such a joy. The paddler has to keep his eyes open, as there are pinning spots to avoid (especially at low water) and some play holes to enjoy, but for the most part, it's a fun slalom adventure. About a mile downstream, soon after a good play hole, comes First Island. This is a pair of narrow slots separated by a narrow, deceptively short and fast 'pool.' The second slot requires a solid right boof against the flow that tries to land the paddler into a very unpleasant rock.
Coordinates from Jeff Macklin (verified by GPS). The coordinates of the end of this rapid are 39.60871, -79.73970.
Soon after First Island, when you see a rectangular concrete wall on River Left, you've come to this rapid, which has a big-ol' ledge-hole at higher levels.
Thanks to Jeff Macklin for the GPS coordinates for this rapid!
Another mile below First Island is...Second Island. Not normally counted among the Big Sandy 'Biggies,' this one is a fun, straightforward Class-3+ boulder hop--unless you go left! If you go left, it's a blind, screaming drop with only a couple of feet of leeway. Call it a Class 5; this is a good rapid for elbow pads, as even a good line can give the paddler an unwelcome shot.
Just a few short yards below Second Island is the takeout, the confluence with the Cheat Canyon, and the beginning of the scariest experience of the day: the shuttle out!

Takeout is at the Jenkinsburg Bridge just upstream on the Cheat River.

Several new trees from summer storms are now in the creek, all are avoidable. The worst is hanging down in the rapid below Little Splat and above Big Splat.

It appears the guy in the white house with the repeat offender white Pittbull has moved. As of last week it looked like new people were moving in. No dogs seen. Run/bike safe, I still recommend a big stick or can of pepper spray for this shuttle by foot.
