Lake Kariba is the world’s largest man-made lake by volume, but not by surface area. The reservoir covers 2,150 square miles and is approximately 140 miles long by 20 miles wide. Lake Kariba is located between Zambia and Zimbabwe.

Natural reservoirs include oceans, glaciers and other bodies of ice, groundwater, lakes, soil moisture, wetlands, living organisms, the atmosphere, and rivers.
