It's really interesting. I live in Detroit. But the Detroit River is actually a straight. The word Detroit is actually a name that comes from the French word detroit meaning "strait". The flag or pendant of Detroit represents the three regimes that once ruled Detroit. The French, the British, the United States, and then the United States once again. The upper right quarter contains three couchant lions, representing Great Britain, which controlled the fort from 1760 to 1796.

A strait is usually wider than a river and has current moving in either direction, with similar altitudes of water at each end. The Detroit river doesn't meet any of these requirements, being 20 miles long and having about a 5 foot drop along the way, with current always flowing in one direction.

I also live by a river, despite it being wider and having current in both directions, connecting bodies that can be considered lakes. It is a estuary, but I've never heard of it being referred to as a strait.

You a native Michigander then?  I am.

It is a narrow bit between 2 large bodies of water. Narrows, strait, passage.
