What is a Levee?
A levee is any artificial barrier together with appurtenant works that will divert or restrain the flow of a stream or other body of water for the purpose of protecting an area from inundation by flood waters.
The terms dike and levee have been used interchangeably in Ohio. Historically a dike is used to divert or restain flood water from tidal bodies of water such as the system of dikes which protect the Netherlands. A levee, on the other hand, diverts or restains flood waters from streams and lakes, such as the system of levees which protect cities along the Mississippi River.
