Lake Lanoto'o is a volcanic crater lake on the island of Upolu in Samoa. It is the largest lake in Samoa.[1] The lake is surrounded by Lake Lanoto'o National Park and is designated as a wetland of international importance under the Ramsar Convention.[2]
The lake is 400m (1,300feet) long with a maximum depth of 17m (56feet) and an area of 11 hectares,[3] with a water temperature of 27.8C and a pH of 5.72.[4] The crater is between 100,000 and 1 million years old.[3]
Sediment cores from the lake have been used to date the human settlement of Upolu[5] and of Polynesia,[3] and to study the paleoclimate and past ecology of Upolu.[6]
The lake provides an important habitat for the Pacific black duck and Spotless crake.[1] Goldfish were introduced during the German colonial period.[1]
