Venice under water December 2008 The recent "acqua alta" (high water) in Venice, Italy reached a depth of 1.56 meters (5 ft, 1 in.) on Monday - the deepest flood in 22 years, and the fourth highest flood level in recent history, claimed Venice's Tide Center. The water began to subside on Tuesday, while residents and tourists made their way through the city, hip-waders or not - one man even took the opportunity to ride his wakeboard through Piazza San Marco (until police stepped in). Although this flood was severe enough for the mayor to ask tourists to temporarily stay home, Venetian floods are fairly routine, several occurring every year, and residents usually take it all in stride.

Large parts of Venice were flooded on Monday as heavy rains and strong winds lashed the lagoon city, with sea levels at their highest level in 22 years. Ferry and water taxi services in the city were suspended and Venice's mayor urged people to stay indoors. Tourists and residents struggled to get across the city over raised walkways. The Centro Maree, which forecasts water levels, said sea levels in the Adriatic rose 1.56 meters (5.1 ft) - a level not seen since 1986. (REUTERS/Manuel Silvestri)
