Brazos River

Brazos River Basin

The Brazos River is the 11th longest river in the United States; its headwaters are in New Mexico, and it flows into the Gulf of Mexico. Most likely named the Tokonohono, the river was called “Rio de los Brazos de Dios” by Spanish explorers which translates to “The River of the Arms of God” in English; its modern name is simply the “Brazos River.”
