Wasserspiegel vs Spiegel
mirror
'der Spiegel' and 'der Wasserspiegel' overlap when talking about water. 'Der Spiegel' can mean the calm surface of a body of water, especially in figurative or descriptive language. 'Der Wasserspiegel' more specifically means the height of the water surface, that is, the water level of a lake, river, or even groundwater. The words can be confusing because 'Wasserspiegel' contains the word 'Spiegel'. If you are talking about a smooth water surface, 'Spiegel' can fit. If you are talking about water rising or falling, 'Wasserspiegel' is more natural.
