Lake Maracaibo is a brackish lake located in northwestern Venezuela, between the states of Zulia, Trujillo, and Mérida. Hydrologically, it is a semi-enclosed bay off the coast of the Gulf of Venezuela. Lake Maracaibo is commonly considered a lake, though due to its current geological characteristics, it should not be considered as such. With a surface area of 13,512 km2 (5,217 sq mi), it is the largest lake in South America and one of the oldest on Earth, having formed disputably as a lake 36 million years ago in the Andes Mountains.
