Maybe?

Depends on what your definitions are and what you're looking for... In
terms of sheer volumes of moving water you'd be hard pushed to beat the
big tidal streams, but even the small constrictions they're passing
through are pretty big compared to what's common in rivers so they're
relatively flat if you're thinking of size in the Z dimension (I'm
thinking turbulence size rather than physical drop, which will obviously
be small).

I think (ICBW) you get about 12 knots through the quick ones, and that's
over a front a good 100m+ wide and deeper than your typical white water,
so that's *vastly* more than the Tay will ever manage and that has the
highest discharge of any UK river.
