similar features to old quarry lake - steep sides and a flatish
bottom. <br>

<div dir="ltr">A few years back I went kayaking in a series of
water bodies created out of old iron ore mine pits [1,2] in
northern Minnesota. These open pit mines were abandoned over 30
years ago. These were some of the clearest lakes I've ever seen.
For those not familiar with Minnesota, it's state motto is "Land
of 10,000 Lakes" which seems ironic when they felt the need to
create a few more.
<div><br>
</div>
<div>I'd be in favor of creating a tag that describes that they
were formed by mining. I'd like to see tags that add to the
existing natural=water and water=lake/pond tags. That way we
can incrementally improve the information without having to
change any existing water body.<br>

And if it's a small area, say with a radius of 30 meters,
would that be<br>
a lake=quarry or a pond=quarry?<br>
I would say that 90% of the times you can easily spot a body
of water in<br>
an old quarry from its surroundings. In the few cases that you
can not<br>
spot that from aerial images (mostly because they have decades
or even<br>
centuries old), you'll not be able to say if it's a lake or a
pond or<br>
the spot was already adopted by the locals as a lake or a
pond, with a<br>
proper name. So I would definitely go with a new tag.<br>
