Sutton Salt Lake in Otago, is New Zealand's only salt water lake.[1]

The lake is filled only by rainwater and dries up during periods of warm weather and little rain.[2]

Sutton Salt Lake is also unique in that it lies in a region of windy cool-temperate maritime climate. This makes it different from most of the world's saline lakes, which usually form in arid continental landscapes. The total area of the lake, when the shallow depression is filled with rainwater, is nearly two hectares. The nearest coast is 50 kilometers from the lake.[3]

The area around Sutton Lake gets 500 mm of rainfall annually. Coastal hills create a minor barrier to the rain, halving the amount of rainfall that the lake receives. Strong winds increase the lake's surface evaporation rate, which is around 700 mm/year.
