The Hurricane Camille high watermark was documented with a plaque by Glenn Swetman on the front steps of his West Biloxi home c.1970. Hurricane Katrina would bring approximately five additional feet of water- enough to have about two feet of water into the house. In their estate the Swetmans left the structure to the City of Biloxi. Since then the building has housed the George Ohr Pottery Museum and the Hurricane Katrina office of the Mississippi Department of Archives & History.

There are similar high water markers on buildings in downtown Providence, Rhode Island, to mark the storm surges from the Great New England Hurricane of 1938 and the hurricanes of 1944 and 1954. Very sobering to consider that streetcars were inundated.

Curious. The Providence markers appear finished or maybe more custom tailored than the two Biloxi markers. I would assume that the two on the Swetman house were commerically available to the public. Maybe more of them could be found on buildings before Katrina?
