Rivers that do not have levees are typically smaller, less developed rivers or those in natural, undisturbed environments. These rivers, often referred to as "wild" or "free-flowing" rivers, can meander freely across their floodplains. Additionally, rivers in arid or semi-arid regions may lack levees due to lower sediment loads and less frequent flooding. In contrast, rivers in urbanized areas are more likely to have artificial levees to manage flood risks.

They are responsible for constructing, monitoring, and repairing levees to protect against floods and manage water levels in rivers and coastal areas.
