Cutthroat Cove Rapid is a deceptively hard rapid. At normal or low flows, if you are reading the water, you will be tempted to enter center or right of center and then work left. This is wrong though, as there is a problem rock located in the center / right of center that is very hard to spot until you are almost right on top of it. The correct line at these flows is left of center all the way. You might scrub on some rocks, but it does better than dealing with the center rocks, which can wrap or turn you over.
At high flows, this is a huge wave train that can turn rafts over. Left is still a good option at these levels as you will need to work away from the bottom right wall as that will come into play.
The fishing in the eddy below the rapid is excellent, especially against the cliff wall.
