Ouachita and Black Rivers Navigation Project

Navigation of the Ouachita - Black river was first authorized in 1871 and consisted of snagging and clearing of the channel. The first stationary lock and dams were built on the Ouachita from 1902 to 1926, and provided a navigable depth of 6.5 feet from the mouth of Black River in Louisiana to Camden, Arkansas on the Ouachita River, a distance of 351 miles. There was a total of six locks and dams spaced at intervals along the river from Franklin Shoals Arkansas to Harrisonburg, Louisiana.

By 1984 all of these dams had been replaced by four modern locks and dams spaced from Calion, Arkansas to Jonesville, Louisiana.
 
The Jonesville and Columbia locks and dams in Louisiana opened to navigation in 1972.The Felsenthal and Calion locks and dams in Arkansas were placed in operation in 1984 and 1985, respectively.

Navigation improvements on the Ouachita River in Arkansas and Louisiana also include 11 bendway cutoffs and 14 bendway widenings.

Fish and wildlife features of the Ouachita-Black navigation project in Louisiana include the Catahoula Diversion Channel and Control Structure, the Little River Closure Dam, and a refuge near Bayou D'Arbonne.

 The diversion channel and structure and closure dams, located in the Jonesville Lock and Dam pool southwest of Jonesville, have been constructed and are in operation.

The channel diverts flows from Catahoula Lake into Black River, downstream from the lock and dam. The control structure is used to regulate the flow entering the diversion channel from the lake. The closure dam is located on Little River. These features allow for regulation of stages in the lake to permit its continued use as a resting and feeding area for migratory waterfowl. Upstream from Columbia Lock and Dam within the Columbia pool area,18,000 acres of land along Bayou D'Arbonnehave been acquired for use as a national fish and wildlife refuge.
