Dam History | AMERICAN DAMS
https://americandams.org/dam-history
The first dams created were gravity dams made of stone, built to divert and guide large, running bodies of water. This evidence can be tracked somewhere between 4,000-2,500 B.C. in Egypt. While the Egyptians made dams of stone, fast-forward 900 years and the Mesopotamians were building dams of soil and clay, known as earth dams.
