It sometimes is used to mark the boundary between East Texas and West Texas.

Another major tributary of the Upper Brazos is the Clear Fork Brazos River, which passes by Abilene and joins the main river near Graham. Important tributaries of the Lower Brazos include the Paluxy River, the Bosque River, the Little River, Yegua Creek, Nolan River, the Leon River, the San Gabriel River, the Lampasas River and the Navasota River. Initially running east towards Dallas - Fort Worth, the Brazos turns south, passing through Waco and the Baylor University campus, further south to near Calvert, Texas then past Bryan and College Station, then through Richmond, Texas in Fort Bend County, and into the Gulf of Mexico in the marshes just south of Freeport. The main stem of the Brazos is dammed in three places, all north of Waco, forming Possum Kingdom Lake, Lake Granbury, and Lake Whitney. Of these three, Granbury was the last to be completed, in 1969. When its construction was proposed in the mid-1950s, John Graves wrote the book, Goodbye to a River. A small municipal dam ( Lake Brazos Dam ) is near the downstream city limit of Waco at the end of the Baylor campus ; it raises the level of the river through the city to form a town lake. This impoundment of the Brazos through Waco is locally called Lake Brazos. A total of nineteen major reservoirs are located along the Brazos.

History It is unclear when it was first named by European explorers, since it was often confused with the Colorado River not far to the south, but it was certainly seen by René - Robert Cavelier, Sieur de La Salle. Later Spanish accounts call it Los Brazos de Dios ( the arms of God ), for which name there were several different explanations, all involving it being the first water to be found by desperately thirsty parties. In 1842, Indian commissioner of Texas, Ethan Stroud established a trading post on this river. Brazos River was the scene of a battle between the Texas Navy and Mexican Navy during the Texas Revolution. Texas Navy ship Independence was defeated by one Mexican vessel. The river was important for navigation before and after the American Civil War, and steam boats sailed as far up the river as Washington - on - the - Brazos. While attempts to improve commercial navigation on the river continued, railroads proved more reliable. The Brazos River also flooded, often seriously, on a regular basis before a piecemeal levee system was replaced, notably in 1913 when a massive flood affected the course of the river. The river is primarily important today as a source of water for power, irrigation, and recreation. The water is administered by the Brazos River Authority. The river also features prominently in a number of prison songs, because at one time nearly every prison in Texas was near the Brazos. The 2000 book, Sandbars and Sternwheelers : Steam Navigation on the Brazos by Pamela A. Puryear and Nath Winfield, Jr., with introduction by J. Milton Nance, examines the early vessels that attempted to navigate the Brazos. On June 2, 2016, the rising of the river required evacuations for portions of Brazoria County. Brazos watershed The Brazos River watershed covers a total area of 119,174 square kilometers. Within the watershed lie 42 lakes and rivers which have a combined storage capacity of 2.5 million acre - feet. The Brazos watershed also has an estimated ground water availability of 119,275 acre - feet per year. Approximately 31 % of the land use within the watershed is cropland. Approximately 61 % is grassland ( 30 % ) shrubland ( 19.8 % ) and forest ( 11 % ) while urban use only makes up 4.6 %. The population density within the watershed is 19.5 people per square kilometer. Water quality concerns The main water quality issues within the Brazos Watershed are high nutrient loads, high bacterial and salinity levels and low dissolved oxygen. These water quality issues can be attributed to livestock, fertilizer and chemical run off. Sources of run off are croplands, pastures, and industrial sites among others. Fracking is also cause for concern regarding water quality within the Brazos Watershed. The Barnett Shale lies partially within the watershed which is the second largest source of natural gas in the US. Studies have shown that the watershed receiving the most toxic pollution is the lower Brazos river which received 33.4 million pounds of toxic waste in 2012. Recreation Canoeing is a very popular recreational activity on the Brazos River with many locations favorable for launching and recovery. The best paddling can be found immediately below Possum Kingdom Lake and Lake Granbury. Sandbar Camping is also permitted since the entire streambed of the river is considered to be state - owned public property. Fishing, camping, and picnicking are legal here, including on the sandbars. Several scout camps are located along the Brazos River and they support a wide range of water and shoreline activities for scouts, youth groups and family groups. The Brazos River Authority maintains several public campsites along the river and at the lakes. Hunting and fishing are also permitted at select locations along the river. Outdoor enthusiasts enjoy the opportunity to find beautiful scenery and abundant wildlife on the river. Fly fishing and river fishing for largemouth bass are popular. Cultural references The Alan Le May novel The Searchers mentions the Salt Fork of the Brazos River several times as a likely place for the protagonists to find Chief Scar, who is holding the captive child Debbie. In the 1956 film based on the novel, Mose Harper identifies the location of Chief Scar 's camp as Seven Fingers, which a group of Texas Rangers identify as Seven Fingers of the Brazos. John Graves ' travel narrative Goodbye to a River takes place on the Brazos River. The Brazos is the setting of the American folk song `` Ai n't No More Cane ''. The `` Upper Brazos River '' is mentioned in a `` King of the Hill '' episode from Season 8 entitled `` Après Hank, le Deluge ''. `` Broke Down on the Brazos '' is the first track on Gov 't Mule 's 2009 album `` By A Thread '' and features a guest appearance by ZZ Top guitarist Billy Gibbons.
