Shinnecock is a lock

Not according to the Army Corps of Engineers. But what do they know?

Not much about this lock. But that could be because they don't maintain it.

Here's one account of the locks from:

"Shinnecock Bay lay to the south of the marina, and entering it requires going through
the Shinnecock canal, which is about a mile and half long. Mid-way through the canal
is the dreaded Shinnecock Lock. Ordinarily the lock operates like any other; the boats
enter, the gates on one end close, and once the water is raised or lowered, the gates
on the opposite end open so that the boats can exit. However, twice a day for about
six hours, the gates remain open. The current rushes through at nearly five knots and
boaters test their skill as they try to traverse the tricky canal. On our first trip
through, Kevin, one of the salesmen, was aboard and we appreciated his advice. Local
knowledge, always invaluable, was never so much appreciated as we negotiated our way
through the canal, through the lock, and into the Bay. "
