Thanks for the waters of this massive river, the entire region around the Brazos River is exceptionally fertile. Wallis, Texas, particularly, has fertile lands with more than 2,000 farms and ranches in Austin County alone.

Thanks to the lush land created by the Brazos River, many settlements came to be along the shores of the river. The fertile farmlands attracted settlers, as well as folks just looking for a good place to live near fresh water. Ports and trade routes found favor along the river, as well, drawing even more communities to the river’s shores.

Flowing along for approximately 840 miles, the Brazos River happens to be the longest river in the state of Texas. The massive river also happens to be the 14th longest river in the entire country, with the river basin covering 45,000 square miles all in all.

The River Was Formerly Known as the River of the Arms of God

Once upon a time, when the Spanish explorers first entered the terrain, the Brazos River was named the Rio de los Brazos de Dios. This name literally translates into English as the River of the Arms of God. One legend suggests the name came from Francisco Vázquez de Coronado who searched for the Seven Cities of Gold in Texas. He and his fellows were about to die due to lack of water when their Native American guides brought them to the river. Their lives were saved, seen like the welcoming, saving arms of God. Thus, the river earned its name, which later shortened to the Brazos River (or “arms”).

Go Paddling, but Don’t Go Swimming in the Salty Water of the Brazos!

The beautiful Brazos River in Texas comes highly recommended for boaters. But high salinity and bacteria should deter swimmers.


While the paddling on the Brazos River is some of the best in the country, the Brazos River Authority has concerned for both the high salinity (saltiness) and bacterial levels of the water. They advise that your activities remain confined to the boats and to avoid swimming for safety reasons.

The Brazos River is Rich with Geological Terrain

One of the most splendid things about the Brazos River is its pathway through some of the most significant geological regions of Texas. The watershed of the Brazos begins west of Lubbock in the High Plains of Texas, resting at an elevation of 1,500 feet approximately, running at a higher elevation through the rest of Austin County. That county alone features more than 650 square miles of fascinating geological sites, from the Post Oak Savannah to the Coastal Prairie region. Nearly all of that county is contained within the Brazos River drainage basin alone.
