DuluthiLeaks: Duluth Foghorn Facts
It’s been 100 years since Duluth’s original diaphone fog siren was installed at the Duluth Shipping Canal. That siren was decommissioned by the Coast Guard in 1968 and replaced by an electric whistle. In 1983 another old diaphone foghorn was acquired and installed. It was used on a ceremonial basis until 1995, then returned to regular service as a maritime aid to navigation. Community members immediately complained it was too loud. The controversy raged on until the horn was dismantled in 2006.
For the sixth edition of DuluthiLeaks — Perfect Duluth Day’s series in which public documents are presented as if they contain secret information leaked from an anonymous whistle blower — we present “Duluth Foghorn Facts,” a document and collection of images compiled by Jeffrey L. Laser of Bellville, Ohio. At some point after 1996, Laser put together the information below, delving into the nitty gritty of the diaphone foghorn that was housed in the Duluth South Breakwater Outer Light from 1983 to 2006.
