Lake Pateriki

Lake Pateriki is a coastal dune lake on northeastern Chatham Island, New Zealand, near the village of Kaiangaroa. Described as brown/yellow or tea coloured, it has a depth of 1.3 metres (4.3 ft) and an area of 134 hectares (330 acres). A narrow sand dune separates its northern shore from the Pacific Ocean; this allows for intermittent outflow to the sea and inflow of saltwater, leading to around 50% seawater by volume. Three streams flow into the lake. It is mildly alkaline, like most other lakes on Chatham Island.^[1][2]
