Can a U.S. State Be Below Sea Level?

No entire U.S. state lies below sea level. However, specific areas within states can be below sea level:

• California: Death Valley (−86 m / −282 ft)
• Louisiana: Parts of New Orleans and coastal wetlands (−2 to −4 m)

Globally, the Netherlands has extensive land below sea level, protected by dikes, pumps, and canals. Such regions rely on continuous water management to prevent flooding.
