Ankle-length or deep?

The past two days, heavy showers bucketed all over Singapore. Some of the low-lying areas were left deluged in the run-off.

Naturally Channel News Asia will report it.

So I saw this article online....

Did you notice that they described the flooding as "ankle-length"?

I thought it ankle-length was reserved for stuff like skirts and dresses.

Can you imagine a ankle-length flood? Wouldn't it look like this police man here.....

Only dry bits are his boots.
