Little River (Louisiana)

From Wikipedia, the free encyclopedia

For other streams and places named "Little River," see Little River.

The Little River is a tributary of the Ouachita (Black) River, about 90 mi (145 km) long, in central Louisiana in the United States.^[1] Via the Ouachita and Red rivers, it is part of the watershed of the Mississippi River. According to the Geographic Names Information System, the Little River has also been known historically as "Bayou Des Nacitoches," "Catahoula Bayou," and "Catahoula River."^[2]

The Little River is formed about 3 mi (5 km) northeast of Georgetown by the confluence of the Dugdemona River and Castor Creek. It flows initially southeastwardly along boundaries of Grant, La Salle, and Rapides Parishes, before turning east-northeaswardly into La Salle Parish through Catahoula Lake, which is bordered by the Catahoula National Wildlife Refuge. After passing through the lake, the Little River continues east-northeastwardly into Catahoula Parish, where it joins the Ouachita River from the west at Jonesville, just downstream of the mouth of the Tensas River.^[3] (Below the mouth of the Tensas, the Ouachita River is sometimes known as the "Black River."^[4])

The state government of Louisiana has designated the uppermost 53 mi (85 km) of the Little River (above Catahoula Lake) as a "Natural and Scenic River." This portion of the river flows through a mixed oak-gum bottomland forest interspersed with stands of bald cypress. Sixty prehistoric Native American archaeological sites have been identified along this stretch of the river.^[5]
