From Wikipedia, the free encyclopedia

Alum Lake is a small freshwater lake west of Wairakei, Taupō District in the North Island of New Zealand. The lake is 0.08 square kilometres (0.031 sq mi) in area, and has a 280 metre shoreline.[1] It is 1 kilometre (0.62 mi) west of Wairakei Geothermal Station, and is surrounded by a forest of a mix of native and introduced trees. There is currently no road access to the lake. Its water is green from algae.

History

[edit]

Like various other lakes in the Wairakei geothermal field, the lake experienced a reduction in depth and surface area in the late 1990s. Geophysicist Chris Bromley commented on the lakes' loss of water, stating that this is why the lakes turned green, and that they were unlikely to refill. Since then, his predictions have remained true.[2]
