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.


No, it also depends on things like the width of the river and whether
there's enough time for the tidal waters to get that far upstream before
the tide turns.

As for the vertical height, according to Environment Agency data the
river in Cambridge is typically 5.1m above sea level.

Denver Sluice was built in 1591 to bar tidal waters any further
upstream. Newton was born in 1623.
