Grassy Creek is a long time favorite of the Russell Fork crowd, a very fun, very doable steep creek. Easy scouting, ledges, slides, continuous and technical.
First run by Jeff "Jabber" Adams and James Stapleton in the early 90's, it's run fairly frequently now. Low to mid level runs are Class III-IV, but large water pushes it to a solid Class V. There are no major undercuts or seives on this run, but the bed narrows to 4-6 feet in a couple of rapids, wrecks can and will leave marks.
The putin is off a wide spot on Highway 80 just below the Gateway Motel (right side as you're heading toward the Breaks Park from Kentucky). The creek runs into Kentucky where it meets the Russell Fork. The takeout is at Ratliff's Hole, a half mile downstream. You should note that the takeout is the regular Russell Fork takeout. Grassy comes into the Fork well below any of Russell's big rapids, just shoals to the takout. The takeout is located at the river access on HWY 80, about 2 miles east of Elkhorn City.
Although the run is pretty continuous, there are 5 significant rapids, in order of appearance:
Split Tail (Lickety Split)
Double Drop
Confluence into Hatfield's Revenge
Big Bang
HyperSlide into Chokehole
The first couple hundred yards is fairly gentle, boulder garden, slide, small ledge combos. After a 5 foot diagonal ledge drop (best run on creek left) you'll be nearing Split Tail. This is the one to carry, if you're going to carry one. A wreck in this one would lead to serious injury. Easily portaged and scouted from creek right. In this rapid, the creek bed pinches down to about 15 feet wide to begin down to about 6 feet at the end. The stream flow is split straight down the middle by a knife of rock that is the creek bed. At low and medium flow, it's entered in a left side seam, sliding about 30 feet through a trough, then dropping 6-7 feet into the narrowest part of the bed, where the split stream comes back together. At high flows, enter and run the right side instead!
Double Drop comes up next after a bit of shoals. Once again, the creek pinches down a bit into 2 quick 6-8 foot ledges with, of course, ledge holes. Best run powering off the left side and maintaining.
A couple more shoals separate Double Drop & Confluence Rapid. Confluence is a 3 parter, beginning with a long, narrow slide that opens back up (the Nozzle) where Center (right) and Laurel (left) Creeks meet Grassy. From there, the bed widens banking right into another banking slide to the left. This slide ends in Hatfield's Revenge, a nasty creek wide hydraulic. This is the longest full rapid on the creek, about 100 yards. Enter Confluence rapid in a seam toward creek right, working left quickly. From there, hang on until the bed opens back up. After you pass the actual confluence, begin working to creek right. Once you get halfway around the curve, a large curling reaction wave is coming off the right bank. Let it take you toward creek left to punch the hydraulic as far left as possible (if you miss the curler get far right and hope for the best).
The next major rapid, Big Bang, is about 100 yards down stream. It will follow some ledges and short slides. This rapid begins with a 7-8 foot slot drop followed by a gentle slide that ends in a 9-10 foot creekwide ledge. You can enter this rapid on either far left or far right, although most take the right hand slot. At the bottom of the slot, work down the center right (without getting too far right) and aim just left of a boulder on the ledge. Boof hard into the eddy below the ledge. If you run it right, you'll hear where it got its name.
Then catch your breath for the grin of the run! Hyper Slide into Chokehole is immediately below Big Bang, an 80 foot long steep, narrow, curving slide that ends in a huge eddy. Ok, it ends in a huge hole, then a huge eddy.
Pull out of Big Bang Eddy and make an exagerated S from left to right to left to right into the main slide (which then comes back left). Don't worry about the hole, you're going so fast at that point it barely slows you down. But it will clear your sinuses!
Now jump out on creek right and carry up & run it again. Below HyperSlide, there are about 200 yards of boulder gardens to the Russell Fork. Watch for pins!
