Two mass fish kills events in August and September of 2022 which saw an estimated 15, 000 dead fish and numerous White spotted eagle rays clog the shores of Mannering Park in Southern Lake Macquarie, has prompted a criminal investigation on behalf of the NSW EPA.
The concentration of affected marine species around the Vales Point power stations cooling water outlet after the first event, as well as footage published of Delta Electricity staff retrieving dead marine life by boat from Wyee Bay directly after the second event, sparked community concern about the role the power station may have had in the incidents.
In January 2023 afer the second fish kill, possible links between the Vales Point power station and the fish kills were investigated by the NSW EPA.
The sale of Vales Point power station to an international company based in Czech, Se.ven was confirmed in December of 2022.

“In my years fishing on the lake, fish kills were always something that happened up at the power station.”
FISH KILL #2 COVERAGE: SEPTEMBER 2022
The findings of the NSW EPA’s investigation into the first fish kill were released August 30th 2022 an cited a combination of low water temperatures and an unusual wind direction as the cause.
In response, the environment drew attention to the role of thermal pollution from Vales Point power stations cooling water discharge, which enters the bay directly from the outlet canal at up to 35 degrees Celsius, well above ambient lake temperature.
Numerous studies, including the 1996 Estuary Management Study of Lake Macquarie attribute thermal pollution to seagrass loss and species assemblage changes, as well as changes in fish species distribution in the thermal discharge zone.
In 2022, marine scientists at the University of Newcastle commenced research into the possible adverse effects on marine life and the ecosystems of both Myuna Bay (where Origin’s Eraring power station discharges its cooling water) and Wyee Bay when these power stations close later this decade, anticipating that "There will definitely be a period where the fish have to adapt to the change.”
As well as dead fish observed lining the shores and afloat in the bay, the discovery of a deceased Whitespotted eagle ray was made near the Wyee Point Marina by citizen scientists taking part in the seagrass survey.
According to local residents in attendance, the ray was one of four or more seen to frequent the area, suspected to have succumbed to oxygen deprivation related to the fish kill. The second fish kill saw additional ray deaths, including a juvenile observed by HCEC on Mannering Park’s shores in September of 2022.
This species is listed as Endangered globally and protected in the Great Barrier Reef, generally preferring warmer, more tropical waters. Like the Green sea turtle, its residency in Wyee Bay is suspected to be linked to the higher localised water temperatures from Vales Point power stations thermal discharge.
