Editing Seine (section)

==Dams and flood control==
Four large storage reservoirs have been built since 1950 on the Seine as well as its tributaries Yonne, Marne, and Aube. These help in maintaining a constant level for the river through the city, but cannot prevent significant increases in river level during periods of extreme runoff. The dams are [[Orient Forest Regional Natural Park|Lac d’Orient]], [[Lac des Settons]], [[Lake Der-Chantecoq]], and Auzon-Temple and Amance, respectively.<ref>{{Cite web|url=http://www.lacs-champagne.fr/en/content/creation-lake-reservoirs|title=LC|access-date=15 October 2019|archive-date=15 October 2019|archive-url=https://web.archive.org/web/20191015172513/http://www.lacs-champagne.fr/en/content/creation-lake-reservoirs|url-status=dead}}</ref>

===Flooding===
A [[1910 Great Flood of Paris|very severe period of high water]] in January 1910 resulted in extensive flooding throughout the city of Paris. The Seine again rose to threatening levels in 1924, 1955, 1982, 1999–2000, June 2016, and January 2018.<ref>[http://www.grid.unep.ch/product/publication/freshwater_europe/seine.php Seine river Basin] {{webarchive|url=https://web.archive.org/web/20070808200310/http://www.grid.unep.ch/product/publication/freshwater_europe/seine.php |date=8 August 2007}}, [[United Nations Environment Programme]] Department of Early Warning and Assessment (accessed 5 June 2007).</ref><ref>{{Cite news |url=https://www.theguardian.com/world/2018/jan/24/paris-flooding-alert-rising-seine-transport-disruption |title=Paris on flooding alert as rising Seine causes travel disruption |last=Willsher |first=Kim |date=24 January 2018 |newspaper=The Guardian}}</ref> After a first-level flood alert in 2003, about 100,000 works of art were moved out of Paris, the largest relocation of art since [[World War II]].

A 2002 report by the French government stated the worst-case Seine flood scenario would cost 10 billion euros and cut telephone service for a million Parisians, leaving 200,000 without electricity and 100,000 without gas.<ref>{{cite news |url=http://news.bbc.co.uk/2/hi/science/nature/1782691.stm |title=Paris flood warning |first=Rory |last=Mulholland |publisher=BBC News |date=25 January 2002 }}</ref>
