I brought this up on the discussion page because no one seems to
know how to tag these features. In my area, in a 2 mile radius,
there are 4 tags for the same "quarry type" lake.<br>
It is forbidden to swim in all of them, not only because is
obviously dangerous, but because they're all in private lands.<br>
In terms of rendering, they're clearly seen if there's already a
landuse=quarry on the spot, because the blue sits over the gray
area:<br>

<br>
water=quarry_lake seems a good fit for these bodies of water.<br>

<div>Hmmm.</div>
<div>Most lakes around here are probably former quarries, but it
is not always obvous.<br>
</div>
<div>What could be of practical interest is, what kind of
activity is lecit on a like: none, swimming, boating, fishing,
ecc.<br>

<div>The origin of the lake is of less importance in my view.</div>

<div dir="ltr">A commenter on the reservoir proposal[1]
pointed out the existence of quarry lakes[2], which is a
lake that is formed after a quarry has been dug after a
mining operation. It was suggested that such bodies of
water should be tagged separately from other lakes with a
tag such as water=quarry.<br>
<br>
Should quarry lakes be tagged under a separate value from
water=lake?<br>
<br>
Should quarry lakes be tagged as a subset of lake, something
like water=lake + lake=quarry?<br>
<br>
If there is consensus that quarry lakes should be excluded
from water=lake, obviously that impacts how water=lake is
defined.<br>
<br>
Existing usages:<br>
water=quarry_lake: 37<br>
water=quarry: 27<br>
water=Quarry: 18<br>
lake=quarry: 1<br>
