I just learned that several days ago a boater swam above the siphon on Suck Hole on the Top Yough and his boat went down it. Fortunately the boater managed to avoid going down the siphon too. (I was not there when it happened, but heard about it from those who were.) The boat disappeared completely. It was down in there for a couple of days, but has since been recovered. At any rate, the logs, etc that had been blocking the siphon for the past few years have shifted... and the siphon is once again open for business. I think a lot of younger boaters dont even know where the Suck Hole siphon is, or how dangerous it can be, since it has been blocked by debris for so long. Be careful and spread the word.

Look behind you next time you are in that eddy and you will see it.)
Alternate takeout: paddle an extra 4 miles of flatwater and run the Upper Yough!
This one's maybe a little smaller and tighter than the Upper Yough. On balance, it's a bit easier, because the continuous rapids aren't quite so big. Nonetheless, it deserves respect and it's a lot of fun.
Gradient, from putin to takeout: 110, 110, 30. In other words, you have two very busy miles before it flattens.
Rapids of note:
Swallow Falls. This is the first rapid, a long slide into a hole. You don't want to go upside-down here,
...
A variety of routes depending on water levels. The scouting rocks on river right are very slippery.
Note: There's a piton rock at the bottom of the slide. In 2012, this was the scene of a back injury. Check out this photo to see the rock at low water.

A big-ol' ledge drop. At higher levels, this can be sticky.
On the river left after Muddy Creek comes in is Best Boof in Maryland. There's a big boulder river left with a horizon line above it which is the boof. A good eddy is formed above it for lining up or giving a first timer beta. Aim for the slight mound, lining up a so you're pointing slightly right of the the boulder. As you get closer you'll see the flake.

Eddy hop down the left. Don't go into the sieve on the right, just below the big rock at the top that hides most of the rapid. This sieve has swallowed numerous boats over the years. It's especially dangerous when it's not jammed full of logs, bottles, tires, woodchucks, and other debris.

Suck Hole at about 130 cfs with a few logs stuck in it. November 29, 2017 I was hiking not boating. You could probably scrape down at this level, but lower than most would be willing to run it.

A duckie that did not quite punch through the curler wave at the top and got shot slightly left. This led him to drop off the ledge that can cause pain for hard boaters. Luckily with a pocket of air beneath him he was fine.
