Plankton bloom in Lake Ōrākei

Plankton blooms are common in a number of nutrient-rich freshwater lakes in the North Island. This photograph shows a plankton bloom in the right side of Lake Ōrākai, Hawke's Bay, and clear water in the left. Silver carp introduced into the left side were able to eat much of the plankton.
