The signature rapid on the Croton.
Left of island: Scouting on river left recommended for blow-downs. At 2-3 feet bumpy and technical (II and up with level) with a fairly straightforward center line thru the steepest part then following the flow left as it flattens out. Hitting eddies, surfing and ferrying can make for exciting moves. At higher water pretty fast and technical 100 yds. Above 4 ft you probably won't be able to eddy out.
Right of Island: Needs a bit more water, but at lower levels is a bit more challenging as there isn't a straight line. Easier route than left at high water. Can have too many overhanging branches to run. Scout from island or river right hiking down from the dam. Can run laps by pulling out near a nearly horizontal tree coming out from the bank on river right as the rapid starts to flatten.
Carry up the center of the Island for laps on river left. If you want to go back to right it's easist to launch above just above the tree mentioned above and ferry across. (Further up you have to carry accoss cobles).
