When the water flow is at its greatest during the daytime, the water
flow actually pushes straight past the actual turn
and enters the whirlpool where the water follows the contour of the
circular edge of the whirlpool and loops counter clockwise back to near
where it entered the whirlpool. At this point, the exit flow of the water passes
underneath (underpass) and intersects the water entering the whirlpool
as it exits north on its way to Lake Ontario.
