When was levees made?

Levees have been used for thousands of years, with some of the earliest recorded examples dating back to ancient Egypt around 3000 BCE, where they were constructed to manage the Nile River's flooding. In the United States, significant levee construction began in the 18th century, particularly in the Mississippi River Valley, to protect agricultural lands from seasonal flooding. Over time, levees have evolved in design and materials, becoming crucial components of flood management systems worldwide.
