A bayou is a body of water typically found in flat, low- lying areas, and can either refer to an extremely slow- moving stream or river (often with a poorly defined shoreline), or to a marshy lake or wetland. Bayous are commonly found in the Gulf Coast region of the southern United States, particularly the Mississippi River region, with the state of Louisiana being famous for them. A bayou is frequently an anabranch or minor braid of a braided channel that is moving much more slowly than the mainstem, often becoming boggy and stagnant, though the vegetation varies by region. Many bayous are home to crawfish, certain species of shrimp, other shellfish, catfish, alligators, and myriad other species. The word was first used by the English in Louisiana and is thought to originate from the Choctaw word bayuk, which means "small stream."[citation needed] Another theory on the origin of bayou is from the French words bas lieu (pronounced phonetically as ba-li- you) meaning "low place".
