When dams are built, they create man-made lakes or reservoirs.
These dams and resulting lakes are important to society as they provide areas with water for drinking, farming irrigation, hydroelectric power generation, and flood management.
While none of the world’s five largest reservoirs are located in the United States, it is interesting to take note just how big these completely man-made bodies of water are.
For comparison purposes, the following list contains the square mileage of several of the lakes in the LakeHomes.com footprint:
Smith Lake, AL: 33 square miles
Lake Lanier, GA: 59 square miles
Lake Murray, SC: 77 square miles
Tellico Lake, TN: 24 square miles
Lake Hartwell,GA/SC: 87 square miles
Kerr Lake NC/VA: 78 square miles

Lake Kariba
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. Studies have shown that the massive amount of water even caused seismic activity in the area, resulting in several earthquakes!
Lake Volta
Lake Volta is located in Ghana and was built in 1965.
This enormous body of water covers a whopping 3,275 square miles and is bigger than the land area of Rhode Island and Delaware combined!
Lake Marion, one of the largest lakes in the South, could fit into the same area almost 20 times over!
There are, of course, bigger lakes by volume, as well as much larger naturally occurring lakes, but when it comes to man-made lakes and areas that they cover, these five take the top spots!
