Today we started our adventure south on the Tenn-Tom waterway.  The Tenn-Tom waterway connects the Tennessee River at Pickwick Lake with the Tombigbee River at Demopolis, AL.  This 253 mile canal was originally proposed back in the late 1700’s by the French as a way of connecting these two navigable rivers, no effort was ever made to complete the waterway until much later. The waters connecting Demopolis, AL to Mobile are called the Black Warrior-Tombigbee Waterway.

Over the years numerous proposals were made to the US Government and finally in December 1972 work began on the canal.  From 1972 to 1985 work progressed on the Tenn-Tom Waterway and after spending nearly 2 billion dollars, the waterway was dedicated on Jun 1, 1985.  This mammoth undertaking moved more earth than was moved in the construction of the Panama Canal, and is relatively unknown throughout the US to the general public.
The waterway shortened the trip for vessels to various ports by as much as 720 miles.  Vessels going from Pensacola, FL to Chattanooga, TN would travel only 771 miles via the Tenn-Tom Waterway instead of 1541 miles via the Mississippi River.  In addition vessels could avoid the swift currents of the Mississippi River when north bound.
The first section of the waterway we encountered was the Divide Cut, at this point the water is at 414 feet above sea level.  The Tenn-Tom Waterway was cut through the backbone of the land here to a depth of as much as 175 feet for a distance of nearly 25 miles.  The Tenn-Tom Waterway has a total of 10 Locks, the first lock will drop us 84 feet, and the remainder will drop us about 30 feet each.

We spotted this bashful coyote, every time I snapped a picture he had his head down.

 
The waterway is narrow but wide enough to pass the tows, this tow was pushing fuel barges, the captain of the tow radioed “Firebird” and ask him if he had a Pontiac emblem on his boat. 

Baffles are placed where the discharge waters of creeks enter the waterway to prevent debris and erosion.

“Moni Jean” and “Firebird” anchored in Cotton Springs, AL.
