Hi,
I don't agree with the deprecation of water=pond. I find it perfect for
small body of water like the ones you can see here for cows watering:

The tag water=pond was added with a large number of other types of
"water=*" in 2011, but it has a poorly defined description.
"A pond <https://en.wikipedia.org/wiki/Pond>: a body of standing
water, man-made in most cases, that is usually smaller than a lake.
Salt evaporation ponds should be tagged with landuse
<https://wiki.openstreetmap.org/wiki/Key:landuse>=salt_pond
<https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dsalt_pond>,
open-air swimming pools — with leisure
<https://wiki.openstreetmap.org/wiki/Key:leisure>=swimming_pool
<https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dswimming_pool>."
So it might be artificial, like a landuse=reservoir or
water=reservoir, but smallish. Or it might be natural like a
water=lake, but smallish. However, nothing on the water=lake page
defines a lower limit for the size of a lake.
This is a shame, because all the other values of water=* are clearly
defined as only natural, or only artificial, and waterway=* features
are also clearly divided. Furthermore, the original lags
landuse=reservoir and landuse=basin were also clearly artificial,
while lakes were natural.
But the biggest problem is that there is no way to define a lower size
for a lake or reservoir, or an upper size for a pond. And the size of
the area is easier available from the geometry of the feature, so it
doesn't need to be mentioned in the tag.
I think the best option is to deprecate water=pond and suggest using
water=lake for natural lakes, even small ones, and use water=reservoir
or water=basin (or landuse=reservoir or =basin if you prefer) for the
artificial ones.
