The river is named for the Native American
Ouachita tribe, one of several historic tribes who lived along it. Others included the
Caddo,
Osage Nation,
Taensa,
Chickasaw, and
Choctaw. The historian
Muriel Hazel Wright suggested that word Ouachita
owa chito is a Choctaw phrase meaning "hunt big" or "good hunting grounds". Before the rise of the historic tribes, their
indigenous ancestors had lived along the river for thousands of years. In the Lower Mississippi Valley, they began building monumental earthwork mounds in the
Middle Archaic period (6000–2000 BC in Louisiana). The earliest construction was
Watson Brake, an 11-mound complex built about 3500 BC by hunter gatherers in present-day Louisiana. The discovery and dating of several such early sites in northern Louisiana has changed the traditional model, which associated mound building with sedentary, agricultural societies, but these cultures did not develop for thousands of years. The largest such prehistoric mound was destroyed in the 20th century during construction of a bridge at
Jonesville, Louisiana. Likely built by the
Mississippian culture, which rose about 1000 AD on the Mississippi and its tributaries, this mound was reported in use as late as 1540 by the Spanish
explorer Hernando de Soto. On his expedition through this area, he encountered Indians occupying the site. A
lightning strike destroyed the temple on the mound that year, which was seen as a bad omen by the tribe. They never rebuilt the temple, and were recorded as abandoning the site in 1736. After the Louisiana purchase, Arkansas became a part of the U.S. and the
Dunbar and Hunter Expedition was commissioned to explore Arkansas which included the length of the Ouachita River from the mouth to
Hot Springs. The Ouachita River was a route used in the
Trail of Tears. Native Americans were transported along the river to
Camden, Arkansas and from there they walked the rest of the way to
Oklahoma. The "Bastrop lands" later passed into the hands of another speculator, former Vice President
Aaron Burr. He saw potential for big profits in the event of a war with Spain following the
Louisiana Purchase. Burr and many of his associates were arrested for treason, before their band of armed settlers reached the Ouachita. During the 1830s, the Ouachita River Valley attracted land speculators from New York and southeastern cities. Its rich soil and accessibility due to the country's elaborate river
steamboat network made it desirable. One of the investors from the east was Meriwether Lewis Randolph, the youngest grandson of
Thomas Jefferson. He was building a home on the Ouachita River in what is now
Clark County, Arkansas, when he died of
malaria in 1837. He had been appointed Secretary of the
Arkansas Territory by President
Andrew Jackson in 1835, and had relinquished his commission when Arkansas became a state in 1836.
Steamboats, 1819 to 1890 Steamboats operated on the
Red River to
Shreveport, Louisiana. In April 1815, Captain Henry Miller Shreve was the first person to bring a steamboat, the Enterprise, up the Red River. During the 1830s, farmers cultivated land for large
cotton plantations; dependent on slave labor, cotton production supported new planter wealth in the
ante-bellum years.
Steamboats ran scheduled trips between
Camden, Arkansas and
New Orleans. A person could travel from any eastern city to the Ouachita River without touching land, except to transfer from one steamboat to another. Trade using steamboats on the Ouachita River became an important part of the local economy and supported many of the communities along the river. In the late 1830s, the steamboats in rivers on the west side of the Mississippi River were a long, wide, shallow draft vessel, lightly built with an engine on the deck. These newer steamboats could sail in just 20 inches of water. Contemporaries claimed that they could "run with a lot of heavy dew". In 1881 a
snagboat was employed on the river and a boat for
dredging in the shoals to the amount of $141,879.24. Earlier plans had called for the construction of locks and dams.
Navigation A 337-mile-long "Ouachita–Black Rivers Navigation Project" began in 1902, to create a navigable waterway from
Camden, Arkansas to
Jonesville, Louisiana, and when completed in 1924 included six locks and dams that were 84 feet wide and 600 feet in length, having from 3 to 5
tainter gates. Including the Black River the total navigable length is 351 miles. The Ouachita-Black Rivers Navigation Project has less than a million tons of shipping annually which has the likely prospect of the future withdrawal of federal support. The project's system of dams and locks enhances the river's recreational use and regional water supply.
Floods Flood of 1882 The Ouachita River reached a historic flood stage crest with a river gauge reading at Camden, Arkansas of 46 feet on May 12, 1882.
Flood of 1927 In Monroe, Louisiana during a flood on May 4, 1927 the high water mark on river gage reading was 48.6 feet.
Great Mississippi Flood of 1927 flooded the areas along the Ouachita Rivers along with many other rivers.
Flood of 1932 In February 1932, the Ouachita River rose 1.5 feet higher than the May 4, 1927 flood. The annual high water mark on river gage readings were 48.6 in 1927 and 49.7 in 1932. The highest water level ever recorded at Felsenthal was 88.3 feet in 1945. ==Natural history==
