On August 24, 1992, Hurricane Andrew crossed southern peninsular Florida. The combined effects of storm surge from the hurricane and astronomical tide, referred to as storm tide, caused flooding over a large part of southern Florida. Subsequent to the flooding, many high-water marks were identified, described, and surveyed along the south- eastern coast of Florida (Miami to Key Largo) and at selected areas along the southwestern coast of Florida (Flamingo to Goodland). Descriptions of these 336 high-water makrs are presented in tabular form in this report and their locations are plotted on nineteen 7.5-minute topographic quadrangle maps. For the southeastern coast, north-south profiles of the high-water makrs along the outher and inner barrier islands and the western shoreline of Biscayne Bay are presented. Average storm-tide elevations (relative to sea level) ranged from 4 to 6 feet in northern Biscayne Bay, were as much as 17 feet on the western shoreline near the center of the bay and ranged from 3 to 6 feet in southern Biscayne Bay and Barnes Sound. Storm-tide elevations along the southwestern coast ranged from 4 to 5 feet at Flamingo and 5 to 7 feet at Goodland in the Ten Thousand Islands area.
