Brazos River

The Brazos proper begins at the confluence of the Salt Fork and Double Mountain Fork, two tributaries of the Upper Brazos that rise on the high plains of the Llano Estacado, flowing southeast through the center of 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, the 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 empties into the Gulf of Mexico in the marshes just south of Freeport. 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. Nineteen major reservoirs are located along the Brazos.

, Republic of Texas. In 1822, the lower river valley of the Brazos River became one of the major Anglo-American settlement sites in Texas. This was one of the first English-speaking colonies along the Brazos and was founded by Stephen F. Austin at San Felipe de Austin. Brazos River was also 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. When it was first named by European explorers is unclear, 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 several different explanations were given, 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. The river was important for navigation before and after the American Civil War, and steamboats 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 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. == Watershed ==

The Brazos River watershed covers a total area of . 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 groundwater availability of 119,275 acre-feet per year. Around 31% of the land use within the watershed is cropland, and roughly 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 50.5 people/sq mi (19.5/km2). == 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 issues can be attributed to livestock waste, fertilizer, and chemical run offs. Sources of run off are croplands, pastures, and industrial sites, among others. 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. The river and its three lakes are popular spots for avid anglers and boat enthusiasts due to the diverse ecosystems in the water and convenient marinas nearby such as The Cliffs Marina. 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 is also permitted at select locations along the river. Fishing is permitted on all of the river, subject to regulations. Outdoor enthusiasts have the opportunity to view the area's scenery and the wildlife on the river. Fly fishing and river fishing for largemouth bass are common. ==See also==
