Big Lagoon, sometimes known as Te Whanganui (both unofficial) is a lagoon beside Cloudy Bay in Marlborough, New Zealand. It outflows into the Pacific Ocean.[1] It is approximately 800 hectares and is part of the Wairau Lagoon, which is connected to Upper Lagoon and Chandlers Lagoon.[2]
There used to be a canal known as Ōrua or previously Morgan Creek which went from Ōpawa River to Big Lagoon.[3] Big Lagoon was previously a wildlife refuge, but this has been lifted and people are now permitted to hunt over the lagoon.[4]
Big Lagoon has beds of Ruppia, Chara and Nitella.[2]
Big Lagoon is in the plate boundary between the Australian Plate and the Pacific Plate. This means that Big Lagoon occasionally experiences strong earthquakes, which may cause liquefaction.[5]
