head of navigation

head of navigation
The farthest point above the mouth of a river that can be navigated by ships. This term can be somewhat subjective on many streams, as this point may vary greatly with the size of the ship being contemplated for navigation. On others it is quite objective, being caused by a waterfall, dam or lock.
