Modern navigation is really taking a toll on the old lighthouses.

There is at least one lighthouse still standing on the Platt River, in
Nebraska. I think it is now a restaurant, it is in use for something.
The Platt is famously said to be " A mile wide, and an inch deep. "
and you don't usually think of it as being navigable.
