Common terms to name individual river distributaries in English-speaking countries are arm and channel. They may refer to a distributary that does not rejoin the channel it has branched from (e.g., the North, Middle, and South Arms of the Fraser River, or the West Channel of the Mackenzie River), or to one that does (e.g. Annacis Channel and Annieville Channel of the Fraser River, separated by Annacis Island).
In Louisiana, the Atchafalaya River is an important distributary of the Mississippi River. Because the Atchafalaya takes a steeper route to the Gulf of Mexico than the main channel, over several decades it has captured more and more of the Mississippi's flow, after the Mississippi meandered into the Red River of the South. The Old River Control Structure, a dam which regulates the outflow from the Mississippi into the Atchafalaya, was completed in 1963. It is intended to prevent the Atchafalaya from capturing the main flow of the Mississippi and stranding the ports of Baton Rouge and New Orleans.
In British Columbia, Canada, the Fraser River has numerous sloughs and side-channels which may be defined as distributaries. Its final stretch has three main distributaries: the North Arm and the South Arm, and a few smaller ones adjoining them.
