As long as the current is significantly faster in the downstream direction,
this qualifies by the standard that "the river current is clearly the
dominating current in the water" - that is, oceanic currents and
wind-driven currents are not the definition characteristic

In contrast, the East River, which is a tidal strait, would need to be
mapped on the marine side of the coastline, since the current flows through
the East River are not related to a fresh-water river current at all.

By using the dominant currents as a definition, this allows local mappers
with knowledge of the water to determine the right tagging.
