A low-head dam.
It is a danger to get caught in a backroller near a low-head dam because the "backroller" is part of a recirculating current which can hold an you against the face of the dam. If you approach too near the "boil line", even from apparent safety downstream, the current may pull you in and you may never escape
One danger of a low-head dam, as opposed to a natural rapids or falls, is that the boil-line extends uniformly across it's face. If you were stuck in a recirculating "hole" in a natural rapids, it's possible that you could swim out to the side to escape. At a low-head dam there is no escape. You may be repeatedly pushed under until you become weak and drown, or you may simply be held against the face of the dam. If you were smart you'd be wearing your PFD. If you were smart you would have avoided the dam!See http://wiki.answers.com/Q/Why_is_getting_caught_in_a_backroller_near_a_low_head_dam_dangerous
