And you are obsessed with Cambridge,

Eh? We have no freight traffic to speak of on the Cam.

Was there ever ?

Yes, all the way up to the Mill.

And was the Cam ever tidal, say in Newton's time, at Cambridge ?

It's an awfully long way from the sea, so no.

That doesn't mean a lot. The Thames would be tidal all the way into Berkshire
if it wasn't for the lock at Teddington. What matters is whether a given
part of the river is above high tide level.
