The Latest on the Anglesea River

Large numbers of fish died in the Anglesea River late last year. These deaths were caused by abnormally high acidic water entering the estuary from the catchment. While this event has happened before in the Anglesea River, particularly when extended dry spells are followed by good rainfall, this time the water has remained acidic for much longer than previously
and the impact was more severe.

The acid comes predominantly from naturally occurring acid sulphate soils in the low lying swampy areas of Marshy and
Salt Creek, which are the main tributaries of the Anglesea River.

The acidic water presents a health risk. Swimming in the river could result in eye or skin irritations in some people and should be avoided.

The river’s water quality was monitored regularly over Christmas and New Year, with acidity levels almost returning to normal. Some small fish and eels were seen in the river. Unfortunately, heavy rain in early January flushed more acidic water into the river from the upper catchment. Small numbers of dead or dying fish and eels have again been reported.

Signs along the river warning people against swimming were to be removed but remain in place as a result.

Council and other relevant government agencies will continue to monitor water quality and advise when acidity in the water returns to acceptable levels.
