🌊 Lake Rotomanu will be drained this week as scientists move to understand the full extent of a freshwater gold clam invasion in one of New Plymouth’s most popular lakes.
The invasive clam Corbicula fluminea, also known as freshwater gold clam, was confirmed in Lake Rotomanu on 8 November - the first time it has been found in New Zealand outside the Waikato River, where it was first detected in 2023.
The lake’s outlet is due to be opened on Thursday 11 December. Taranaki Regional Council expects it will take around four days for the 10-hectare lake to empty. During that period, fish will be harvested in partnership with local hapū Ngāti Te Whiti, with as many as possible to be used.
