Indeed. How to cater for both situations?

The tagging system as a whole will never be entirely consistent, or
even operate on consistent principles. The best we can do is fix small

Hi.
I'm not very familiar with waterway tagging, but AFAIK these are tagged
as riverbanks, too.
Your proposal doesn't say anything about how to map sluice gates at
these bigger rivers as it proposes the usage on nodes only.
As sluice gates assumably will be more on bigger waterways, that

A lot of weirs I've seen don't have any kind of gates, they just
semi-dam a river to provide a water supply for nearby towns, the water
freely flows over the top of the weir.
