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.</div>
<div dir="ltr"><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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. </div>
<div><br>
</div>
<div>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. </div>

<p>This doesn't seem like a good idea to me. The boundary between a
lake and a pond may be hard to measure sometimes, but that doesn't
mean it is useful.</p>
<p>If we squash detail from tagging we are left with nothing. Maybe
we should just tag everything as thing=yes?<br>
