Public Health Advice - Red Algal Blooms Waipu Cove and Bream Bay areas
This week the Northland Regional Council continued to investigate the Red algal bloom in the Waipu estuary. The warm and relatively shallow conditions in the lagoon were probably initially favourable for the red algae to continue to grow, but that had changed once the algae began to die with its resulting decomposition consuming much of the oxygen in the water. In the upper area of the lagoon there’s very little circulation and exchange of water with the open coast and NRC recorded very low dissolved oxygen concentrations in the lagoon.
