Two mass fish kills events on August 6 and again on September 5 of 2022 saw an estimated 15, 000 deceased fish and numerous White spotted eagle rays clog the shores of Mannering Park in Southern Lake Macquarie. The second incident prompted a criminal investigation into the role of Delta Elecricity’s Vales Point power station by the NSW EPA.

The concentration of floating fish and rays around the Vales Point power stations cooling water outlet in Wyee Bay after the first event and 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.

The sale of Vales Point power station to an international company based in Czech, Se.ven was confirmed in December of 2022.

The investigation

One year to the day of the second fish kill, the NSW EPA investigation concluded with criminal proceedings being lodged against Delta for a breach of its licence conditions - failure to maintain plant equipment in a proper and effcient manner - alleged to have allowed a lethal does of chlorine to enter Wyee Bay via the Vales Point outlet canal.

The case

Delta Electricity entered a plea of not guilty in the in the NSW Land & Environment Court, Friday April 19.

The alleged offence constitutes a breach of section 64 of the Protection of Environment and Operations Act and can attract up to a one-million-dollar penalty.

Delta’s impacts on fish abundance in Lake Macquarie extend far beyond these most recent episodic fish kills to encompass decades of lost productivity of seagrass from exposure to thermal pollution which has entirely stripped Wyee Bay of Zostera seagrass.

Read our expose of Delta’s dirty deeds which delves into the detail of Vales Point power stations long-running pollution impacts on the Lake Macquarie estuary, and our proposals to see the mess cleaned up and the lake restored upon coal power closure.

You can’t tell me the power station is not the culprit.

The power station was the cause. I saw dead fish coming out the canal.

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

FISH KILL #1 COVERAGE: AUGUST 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.
