2022 Map of Open Lake

About this map

The Mississippi River creates a dynamic border between Lauderdale County, Tennessee and Mississippi County, Arkansas in this survey of the river's alluvial bottomlands. The landscape is defined by its complex hydrology, featuring numerous oxbow lakes and sloughs such as Open Lake, Swan Lake, and Chisholm Lake that trace the historical migration of the river channel. This area reflects a specialized river-and-bottomland economy, where navigation and drainage are primary concerns, indicated by features like the Bend of Island Number Twenty-five and Lassiter Bar.
