Shown on the Gulf Shores topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of the Gulf of Mexico, Oyster Bay, and the Bon Secour River, in Alabama. Most beachfront homes in the Gulf Shores area and most homes fronting on Little Lagoon in western Gulf Shores were either destroyed or heavily damaged. All beachfront motels were severly damaged. Damage to homes and other buildings in the Oyster Bay-Bon Secour area was not as great. Storm-tide frequency and records of annual maximum tides at Mobile, Ala., since 1772, are presented. Offshore winds reached about 160 miles per hour. A wind-velocity of about 145 miles per hour was recorded near Dauphin Island, Ala. (USGS)
