Environment Protection Authority Victoria (EPA) has flagged extremely dry seasonal conditions could lead to further fish deaths in Victoria this summer.
EPA Executive Director of Regional Services Damian Wells said fish deaths at Avoca River in Charlton and Lake Colac earlier this month were caused by natural drying of waterways and low water flow conditions.
“The prolonged period of below average rainfall across Victoria has significantly reduced water levels of inland waterways – particularly in the north, north-west and south-west of the state,” Mr Wells said.
“Drying is a natural process. In some cases, lake beds can dry completely and remain dry for long periods.
“Dead fish degrade naturally and are usually cleaned up by birds and other natural elements.”
Mr Wells said EPA investigated reported fish deaths and works closely with the Department of Environment, Land, Water and Planning, water corporations and catchment management authorities to manage fish death events over summer.
Members of the community are urged to contact EPA’s Pollution Hotline on 1300 372 842 (1300 EPA VIC) if they see large numbers of fish, crustaceans and/or eels that appear to be dead or struggling.
