Lake Maracaibo (below) is a large brackish bay in Venezuela. It is connected to the Gulf of Venezuela by Tablazo Strait (55km) at the northern end, and fed by numerous rivers, the largest being the Catatumbo. It is commonly considered a lake rather than a bay or lagoon, and at 13,210 km² it would be the largest lake in South America.
While the lake appears mostly sediment-free, tan and green sediments can be seen in the Gulf of Venezuela to the north. It is a gulf of the Caribbean Sea bounded by the Venezuelan states of Zulia and Falcón and by Guajira Department, Colombia. Also of note in the image is the city of Maracaibo, visible as a grey area on the western bank of the Tablazo Strait.
