Native Americans Native American cultures along the river were diverse, developing specialized adaptations to the many different environments. Having threaded the maze of
bayous at the river's confluence and the "
Great Raft" of lodged driftwood, the expedition was stopped by the Spanish near present-day
New Boston, Texas. In 1806,Lieutenant
Zebulon Pike, under orders to ascertain the source of the Red River, ascended the
Arkansas River, made his way downstream on what turned out to be the
Rio Grande, and was sent home by the Spanish authorities. A more successful exploration of the river's upper reaches to both its sources came with the 1852 expedition under Captain
Randolph Barnes Marcy, assisted by Brevet Captain
George B. McClellan. A decade later McClellan became an important general in the
American Civil War. In April 1815, Captain Henry Miller Shreve was the first person to bring a steamboat, the
Enterprise, up the Red River. Fulton and Livingston, who claimed the exclusive right to navigate Louisiana waters by steamboat, sued Shreve in the District Court of New Orleans. The judge ruled that the monopoly claimed by the plaintiffs was illegal. That decision, along with a similar outcome in
Gibbons v. Ogden, freed navigation on every river, lake or harbor in the United States from interference by monopolies. When
John Quincy Adams became
Secretary of State in 1817, one of his highest priorities was to settle with Spain the boundaries of the
Louisiana Purchase. He negotiated with
Luis de Onís, the Spanish minister to the United States, and finally concluded the
Adams–Onis Treaty, also known as the Treaty of 1819. The treaty defined the south bank of the river as the boundary between the United States and Spain, as of when it was surveyed and demarcated following 1819. That boundary continued to be recognized when
Mexico gained its independence from Spain in 1821, and ongoingly when
Texas became independent from
Mexico in 1835–1836. It remained the official boundary
2015 Red River flood In June 2015, the
Red River flooded parts of northeast Texas, southwest Arkansas, southeast Oklahoma and Louisiana, from
Denison Dam to just south of
Alexandria, Louisiana. The river reached its highest level in over 70 years, cresting in most of the affected areas at around 6–9 feet over the flood levels. At 4 PM on June 9, the river reached its maximum height of 37.14 feet. Bridge, atop the Red River between
