Early peoples obtained oysters from the bay, which were eliminated due to changes in salinity after the full formation of Laguna Madre. The first people to encounter the new lagoon were most likely the nomadic Karankawa and Coahuiltecan Indians. The Spanish explorer Alonso Álvarez de Pineda is believed to be the first European to come in contact with Laguna Madre in the early 16th century, and is credited with giving it the name, which is Spanish for "mother lagoon". Several land grants were handed out by the Spanish government for ranching near the lagoon.
