DAVENPORT — Salvage operations for a sunken towboat on the Mississippi River at LeClaire have been slowed as workers cope with below-freezing temperatures, which are expected to linger for days.
Workers had hoped to raise the bow of the sunken Stephen L. Colby by Friday but were unable to do so.
U.S. Coast Guard Petty Officer 2nd Class Jaclyn Young said workers are able to spend only two hours outside before they must be cycled through a warming tent.
Divers are allowed to be in the water for only 30 minutes.
A second salvage team arrived Saturday to help float the 144-foot towboat, which sank Nov. 25 off the LeClaire levee after striking a submerged object. All nine crew members of the vessel made it to safety.
