Soil [[subsidence]] also destroyed buildings, deepened local rivers, and created wetlands in places like the [[Río Cruces]] and Chorocomayo, a new aquatic park north of the city. Extensive areas of the city were flooded. The electricity and water systems of Valdivia were totally destroyed. Witnesses reported underground water flowing up through the soil. Despite the heavy rains of 21 May, the city was without a water supply. The river turned brown with sediment from landslides and was full of floating debris, including entire houses. The lack of [[potable water]] became a serious problem in one of Chile's rainiest regions.{{citation needed|date = May 2012}}<eod>
