The Hudson definitely reverses flow. One of its names among the First
Peoples translates to 'the river flows both ways.' The division in the
flow lies less in the fraction of the tidal cycle than the speed of the
current. It flows 'upstream' for half the time, 'downstream' for half, but
the downstream current is considerably swifter.
