Red tide - what does this mean?
From time to time a phenomenon commonly known as a ‘red tide’ can occur at in waterways and at beaches.
A ‘red tide’ is a marine environmental event, where tiny organisms, such as algae, go through an intense growth period (called an algal bloom), which can colour the waters red.
The red colouring comes from the algae and is a natural occurrence, not a pollutant.
You can read more about red tides here on the Derwent Estuary Program website.
