There is a tide lock at the St. Peter (SW) end. Each end of the lock
has gates facing both ways. It prevents flow in and out.

How does having this configuration have any advantage? I've never
seen a lock like this.

Half the time the water is higher on the lake side (low tide in ocean) and
then it's higher in the bay end (high tide in ocean)

Got it! Obviously my experience with locks is limited.

Thanks!

Don't feel bad. They claim this system is unique in North America.

It is the only one I have seen. There is very little vertical
movement. The gates close in a shallow V, so the water pressure holds
them closed, whrn it pushes on the pointy side. Thus:

I hope this makes sense. represents a gate that opens to the left.

Its main purpose is to prevent rapid currents.
