The Atchafalaya River is located in central Louisiana. The 170 mile river is fed by the Mississippi and Red Rivers, which are connected via the Old River Lock. Navigation is therefore reduced by almost 172 miles for vessels sailing between the Mississippi above the Old River Lock and the Intracoastal Waterway in southern Louisiana saving time, money, energy and reducing river traffic congestion near the Port of New Orleans.

The USACE Navigation Data Center – Waterborne Commerce Statistics Center reported that in 2009, 13,619,674 tons of commodities were transported on the Atchafalaya River.

The Atchafalaya River is a natural outlet for the Atchafalaya River Basin and it is the only riverine area building new ground near the Gulf of Mexico. The U.S. Army Corps of Engineers (USACE) is responsible for providing data pertaining to navigation on and along the river. As part of a comprehensive mapping project, the USACE develops updated flood control and navigation maps as well as hydrographic survey maps for the Atchafalaya River.

Updated Features include:

• Land/ Water interface (New Bankline)
• Depth Areas
• Boat Ramps/ Pipelines
• Navigation Lights
• Bridge Lights
• Buoy Locations
• Revetments
• Notes (Facilities, Bridge Profiles, etc.)

A Geospatial PDF refers to a Portable Document Format (PDF) with certain geospatial encoding that relates a region on a PDF document page to a region in physical space. The establishment of this relationship is a process called georeferencing. The georeferencing metadata in the provided files uses the Adobe PDF 1.7 specification for writing geospatial PDF files. The creation of Geospatial PDFs has enabled the new 2012 Atchafalaya River and outlets to Gulf of Mexico Navigation Chart Folio to be imported into location aware applications. Avenza Systems’ free Apple iOS application called PDF Maps allows users to download USACE chart files and view them on an iOS device and received real time GPS locations. The Upper Mississippi River (Minneapolis, MN to Cairo, IL) and the Atchafalaya River Charts are currently available in the application store.   NOTICE: These Geospatial PDF Navigation charts are provided for informational purposes only.
