Why Is Lake Maracaibo Called a "Lake" If It's Connected to the Sea?

Lake Maracaibo is a partially enclosed bay (lagoon), not a true lake. It connects to the Gulf of Venezuela and the Caribbean Sea via the 54-km (34-mi) Tablazo Strait. However, it retains the name "lake" for historical and hydrological reasons:

• Historical naming: Spanish explorers (1499) called it a lake due to its vast size (13,210 km²) and brackish water.
• Limited tidal exchange: The narrow strait restricts seawater inflow, creating a unique brackish ecosystem (freshwater from rivers like the Catatumbo atop denser saltwater).
• Geological origin: It occupies a tectonic depression—a former marine basin isolated by sediment buildup.

Geologically, it's a restricted coastal lagoon; colloquially and legally (Venezuela's "Lake Maracaibo Basin"), it remains a "lake."
