Map of the St. Francis River watershed. The Castor/Whitewater headwaters (darker shade on the map) were historically part of the St. Francis watershed but are now diverted to the Mississippi.
The St. Francis River is a tributary of the Mississippi River, about 426 miles (686 km) long,[4] in southeastern Missouri and northeastern Arkansas in the United States. The river drains a mostly rural area and forms part of the Missouri-Arkansas state line along the western side of the Missouri Bootheel.
Description and course
The river rises in a region of granite mountains in Iron County, Missouri, and flows generally southwardly through the Ozarks and the St. Francois Mountains near Missouri's highest point Taum Sauk. It forms the Missouri-Arkansas border in the Bootheel and eventually exits the state at Missouri's lowest point in the "toe" at 241 feet (73 m) above sea level. It passes through Lake Wappapello, which is formed by a dam constructed in 1941. Below the dam the river meanders through cane forests and willow wetlands or forested swamp, transitioning from a clear stream into a slow and silt-laden muddy river as it enters the flat lands of the Mississippi embayment. In its lower course the river parallels Crowleys Ridge and is part of a navigation and flood-control project that encompasses a network of diversion channels and ditches along it and the Castor and Little rivers. Below the mouth of the Little River in Poinsett County, Arkansas, the St. Francis is navigable by barge. It joins the Mississippi River in Phillips County, Arkansas, about 7 miles (11 km) north of Helena.
In addition to the Little River, tributaries of the St. Francis include the Little St. Francis River, which joins it along its upper course in Missouri; the Tyronza River, which joins it in Arkansas; and the L'Anguille River, which joins it just above its mouth.
History
The river became the home of Cherokee Indians who attacked a boat on the Tennessee River on June 11, 1794 known as the Muscle Shoals Massacre and had removed to the west.[5] The Spanish authorities allowed the Indian settlement to trade and the area flourished with a population greater than Arkansas Post.
Names
The origin of the river's name is unclear. It might refer to St. Francis of Assisi, the founder of the Franciscan order. None of the region's early explorers were Franciscans, however. One possibility is that Jacques Marquette, a Jesuit, named the river when he explored its mouth in 1673. Before his voyage down the Mississippi Marquette had spent some time at the mission of St. François Xavier, named for the Jesuit missionary Francis Xavier. The spelling of the river's name shifted from "François" to "Francis" in the early 20th century. A number of place names in the region stem from the river's name, including St. Francois County and the St. Francois Mountains.[6]
