Hi 

I will get on to the mapper that created the tags and see how we go from there. I agree that in Africa they are not called 'ponds', usually slimes dams or mine dumps. In fact we use the term 'dam' to refer to the water held back by a dam wall whereas the technically correct term is 'dam' for the wall and lake or reservoir for the impounded water. In parts of the world the 2 can have 2 different names, Lake Mead in the US is held back by the Hoover Dam for example. Here we say Lake Kariba is impounded by the Kariba dam wall.
