WHN - high tide at the sea lock

Extreme High Spring Tide. [30th September 2019]

There is sufficient water in the sea lock to overtop the inner gates, although the marina is already quite full.

(It is usual to allow some exchange of water, usually accomplished during "free flow" when both sets of gates are opened. With a tide this high, the gates are closed during the highest part - so there are two "free flow" sessions)
