Ok, so you’ve noticed that many lakes are tagged as natural=water only,
correct? It is recommended to add water=lake, but because natural=water is
sufficient to get a water area to render on most maps, I believe many
mappers don’t bother to add the more precise tags.

I don’t know Russian and Google Translate is not helping, but I would
recommend tagging all small man-made ponds as natural=water plus
water=pond. If пруд and копанка are two types of pond that can be clearly
distinguished, then you could try to translate these words and make up a
sub-category for ponds, eg pond=копанка or better pond=<копанка translated
into British English>, which could be added in addition to water=pond.

(Also note that larger artificial water bodies are called reservoirs in
English rather than ponds, so there is already one distinction)

Could you describe the physical difference between a пруд and a копанка?
