Real time information on when it is not safe to swim in Adelaide coastal beach waters are available on the EPA website.
The beach alert icon will appear on the EPA website home page when stormwater is discharging into the sea.
Beaches in Adelaide are safe and healthy for 98% of the time. However, the water quality can be impacted by rainfall which flushes stormwater into the sea leaving discoloured water especially around drains.
There is a network of stormwater drains across the metropolitan area that collects run off from the streets and gutters when it rains and flow to the sea, creeks and rivers situated along the Adelaide Plains. These include the River Torrens, Barcoo Outlet, Onkaparinga River and Christies Creek.
The EPA sources real-time stormwater flow data from Natural Resources Adelaide and Mt Lofty Ranges to inform beach goers when stormwater is being discharged into the marine waters near the metropolitan beaches.
The beaches being monitored are from Semaphore in the north to Noarlunga in the south.
This summer there will be a further phase in the trial to control cyanobacterial algal blooms in the Torrens Lake. The trial will involve flows of fresh water into the lake which will result in flows downstream to the Torrens outlet at Henley Beach, possibly triggering a Beach Alert. The trial is designed to minimise water quality impacts on beach users and monitoring will occur to confirm this. Remember to avoid swimming in discoloured water. For further information, visit Natural Resources Adelaide and Mt Lofty Ranges website.
