12 Flooding of historic proportions in Horseshoe Beach. Elevated structures experience significant flooding and could be destroyed by wave action.
9 Catastrophic flooding in Horseshoe Beach. Complete inundation of the area. Homes not elevated will likely be destroyed. Some structures that are elevated begin to flood and experience damage.
6 Significant flooding in Horseshoe Beach. Structures not elevated suffer flooding with up to 3 feet of water inside.
5 Nearly all of Horseshoe Beach is inundated with structures not elevated flooded with water up to 2 feet deep.
4 County Road 351 floods, making entry into Horseshoe Beach impossible. Most land areas in Horseshoe Beach are flooded. Structures not elevated have up to 1 ft of water inside.
3 Water approaches the top of the bank at Main Street and West 1st Avenue near the city limits of Horseshoe Beach. Structures near canals not elevated are prone to flooding above this level.
