The iconic rowing boats have been left stranded after a winter of little rain and snow resulted in unusually low water levels in the canal-filled northeastern city. Concerns also have mounted that Italy could be in for another drought after last summer’s emergency, according to the outlet, which cited scientists and environmental groups. In addition to the lack of precipitation, arid conditions in Venice are being blamed on a high-pressure system, a full moon, low tides and unfavorable sea currents. Gondolas and water buses known as vaporettos have been left high and dry as a result.
