Columbia Bottom Conservation Area is located in north St. Louis County at the confluence of the Missouri and Mississippi Rivers and is prone to occasional flooding. The Conservation Department purchased this 4,318 acre area in 1997 to create an urban conservation area. It includes a view of the confluence of the Missouri and Mississippi rivers, over 6.5 miles of river frontage, about 800 acres of bottomland forest and a 110 acre island. A flood protection levee protects most of this bottom from minor floods. The great flood of 1993 over topped this levee and flooded most of the land leaving behind sand deposits and debris.
