Jul 07, 2010 — Coast Guard crews shifted ballast and cargo to re-float the Canadian freighter, Algobay, last night. The 740-foot long ship lost power Sunday morning and ran aground on Superior Shoal, near Chippewa Bay. That's not far downriver from where an oil tanker ran aground in 1976. The 1976 spill, known locally as the Slick of '76, remains one of the biggest inland oil spills in the country's history.

A spokeswoman for the St. Lawrence Seaway Authority said there was no threat of fuel leaks or other pollution from the Algobay. Martha Foley has more.
