Lake Ohakuri, at {{convert|12|km2}}, is the largest artificial lake of the Waikato river system in New Zealand. It forms the reservoir for the Ōhakuri hydroelectric power station. Construction of the dam, approved in 1955, began in 1956 and was completed in 1960.{{cite web|url=http://www.mightyriverpower.co.nz/generation/aboutus/hydrostations/ohakuri/default.aspx |title=Ohakuri |publisher=Mighty River Power |accessdate=2008-02-13 |url-status=dead |archiveurl=https://web.archive.org/web/20110927043038/http://www.mightyriverpower.co.nz/generation/aboutus/hydrostations/ohakuri/default.aspx |archivedate=2011-09-27 }} The lake was filled over 14 days in January and February 1961. This drowned two thirds of the Orakei Korako geothermal area, including two of the world's largest geysers, Minginui Geyser and Orakei Korako Geyser.{{cite web|archiveurl=https://web.archive.org/web/20090402110522/http://www.wyojones.com/tall.htm |archivedate=2009-04-02 |url=http://www.wyojones.com/tall.htm |title=Tall Geysers |publisher=Minority Geoscience Program, University of New Orleans |first=Gregory |last=Jones |year=2006 |url-status=dead }}
