The 2013 Mississippi River Hydrographic Survey Book maps the river channel depths and overbanks from Black Hawk, LA (Mile 324 AHP) to the Head of Passes (Mile 0), South Pass, Southwest Pass, and Pass A Loutre.

Newly added to the map coverage in this 2013 publication is the history of hydrographic surveys done on the Mississippi River and their importance.

The publication's purpose is to provide a current comprehensive survey and map of the Mississippi River and adjacent locals for recording changes resulting in cutoffs, channel stabilization works, channel enlargements, and river control works, and for use as an engineering and planning tool on future Corps projects.

The Hydrographic Survey Book consists of 74 map sheets mapped to 1:20,000 publication scale and 12 map sheets mapped to 1:10,000 scale. Each map sheet is available for download below in Adobe PDF format and MicroStation DGN format.
