A reservoir is primarily defined as a lake or storage area created by damming a river or stream, where water is collected and stored for various uses, such as municipal water supply, irrigation, hydroelectric power generation, and recreation. While the term can also refer more broadly to any storage space for water, including underground aquifers, in the context of human engineering and management, it most commonly refers to surface water bodies created by dams.
The second definition you provided describes an aquifer, which is indeed an underground layer of rock or sediment that holds water, but it is not typically referred to as a reservoir in the conventional sense.
In summary, a reservoir generally refers to a man-made lake created for the storage of water, while an underground water layer is considered an aquifer.
