streets in Cork city centre have been affected by floods more than 100 times since the mid-19th century. 2009 flooding In late 2009 the river flooded, causing some of the most significant damage in Cork city for a number of centuries. The Lee Water Station was forced to shut down after being submerged under six metres of water, and resulted in 40% of Cork City (50,000 people) being without running water for over a week. Lower-lying parts of the University College Cork campus were also flooded extensively, resulting in lectures being cancelled throughout the week. There was severe damage to the university's then newly built IT building, the Western Gateway Building, situated next to the river on a known floodplain, where, for example, a 300-seat auditorium was flooded to near ceiling height. To prevent issues upstream, the ESB made a controversial decision to release water from the Inniscarra hydro-electric dam. This released 535 tonnes of water per second into the already flooded river, raising the flood to 1.5 metres in parts of the city centre. The ESB insisted this was an essential move, and if water had not been released, the flooding would have been much worse.
