Confederate shipwreck in way of Savannah river dredging

By Russ Bynum - The Post and Courier

Before government engineers can deepen one of the nation’s busiest seaports to accommodate future trade, they first need to remove a $14 million obstacle from the past – a Confederate warship rotting on the Savannah River bottom for nearly 150 years.

Confederate troops scuttled the ironclad CSS Georgia to prevent its capture by Gen. William T. Sherman when his Union troops took Savannah in December 1864. It’s been on the river bottom ever since.

Now, the Civil War shipwreck sits in the way of a government agency’s $653 million plan to deepen the waterway that links the nation’s fourth-busiest container port to the Atlantic Ocean. The ship’s remains are considered so historically significant that dredging the river is prohibited within 50 feet of the wreckage.

So the Army Corps of Engineers plans to raise and preserve what’s left of the CSS Georgia. The agency’s final report on the project last month estimated the cost to taxpayers at $14 million. The work could start next year on what’s sure to be a painstaking effort.

And leaving the shipwreck in place is not an option: Officials say the harbor must be deepened to accommodate supersize cargo ships coming through an expanded Panama Canal in 2014 – ships that will bring valuable revenue to the state and would otherwise go to other ports.

Underwater surveys show two large chunks of the ship’s iron-armored siding have survived, the largest being 68 feet long and 24 feet tall. Raising them intact will be a priority.

Researchers also spotted three cannons on the riverbed, an intact propeller and other pieces of the warship’s steam engines. And there’s smaller debris scattered across the site that could yield unexpected treasures, requiring careful sifting beneath 40 feet of water.

“We don’t really have an idea of what’s in the debris field,” said Julie Morgan, a government archaeologist with the Army Corps. “There could be some personal items. People left the ship in a big hurry. Who’s to say what was on board when the Georgia went down.”

Also likely to slow the job: finding and gently removing cannonballs and other explosive projectiles that, according to Army Corps experts, could still potentially detonate.
