Doesn't mean they shouldn't be updated/added if there is a better tag...

I actually think we need some way to indicate scale, wikipedia seems
to indicate sluice gates are usually on the small side of things,
spillway gates are usually much larger, for a good example of spillway
gates see the photos Liz linked to of Wivenhoe and Somerset, those
dams were specifically built to reduce or prevent Brisbane (state
capital of Queensland Australia) from flooding. In fact Wivenhoe was
upgraded in recent times to hold 200% normal operating capacity.

As for floodgates these aren't usually closed except in times of
flooding and should be tagged differently again so they can be
rendered differently for those that care about such things.
