Bayou Bienvenue

Bayou Bienvenue is a 12.1-mile-long (19.5 km)bayou in southeastern Louisiana. It runs along the political border between Orleans Parish and St. Bernard Parish to the east of New Orleans.

The bayou crosses the Gulf Intracoastal Waterway and Mississippi River Gulf Outlet, before ending in Lake Borgne, a shallow estuarine lake branching from the Mississippi Sound.

A short distance from the Lake end of Bayou Bienvenue, the remains of Battery Bienvenue still guard the eastern approach to the city. This fortification was built shortly after 1815's Battle of New Orleans to prevent any future invasion of the city by way of the Lake and Bayou.

A bayou (/ˈbaɪ.oʊ/ or /ˈbaɪjuː/) is a Franco-English term used in the United States for a body of water typically found in a flat, low-lying area, and can refer either to an extremely slow-moving stream or river (often with a poorly defined shoreline), or to a marshy lake or wetland. The name "bayou" can also refer to a creek whose current reverses daily due to tides and which contains brackish water highly conducive to fish life and plankton. Bayous are commonly found in the Gulf Coast region of the southern United States, notably the Mississippi River Delta, with the states of Louisiana and Texas 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 fauna varies by region, many bayous are home to crawfish, certain species of shrimp, other shellfish, catfish, frogs, toads, American alligators, American crocodiles, herons, turtles, spoonbills, snakes, leeches and myriad other species.
