This rapid lies just below the outflow from Ball Mountain Dam. If you take the shuttle up from Jamaica State Park carry across the footbridge over Cobb Brook and walk ~1/3 mile upstream to the base of the dam. There is a nice eddy river left of the dam discharge. Just downstream from the eddy put in the river drops through the heaviest whitewater on the West. A center route will take you through a series of holes and standing waves a few rocks are scatered throughout. As the river takes a gradual left look for an eddy on river left that services a nice surfing wave. Below this playspot the river eases up a bit but look out for a couple tough sections especially next to two large boulders the first on river right the next a short way downstream on river left.
