A release of fresh water into the River Torrens started this afternoon (Wednesday 7 March) as part of the annual program to control algal levels in the river and Torrens Lake during summer and the autumn events season.
Katharine Ward from Natural Resources Adelaide and Mt Lofty Ranges said the release would continue through until next Wednesday (14 March).
“This past summer (2017-18) marks the fifth in a row where we’ve been successful in preventing the closure of Torrens Lake due to blue-green algal blooms, which were common in the lake during summer over many years.
“The strategy of using flows of fresh water has kept the Torrens Lake healthy throughout summer but the program is also designed to improve water quality along the entire length of the Torrens from the hills to the coast.”
Following the release of the water, local residents and visitors to the River Torrens Linear Park may notice higher-than-usual flows in the river for up to four days as water makes its way from the hills, through the city to the Torrens outlet at Henley Beach South.
Water resulting from the flows will be of a better quality than stormwater. However, as with all flows into the sea from urban areas, beach goers are encouraged to avoid swimming in turbid or discoloured water.
The River Torrens Water Quality Improvement program was developed with the support of the Adelaide and Mount Lofty Ranges Natural Resources Management Board, the Department of Environment, Water and Natural Resources, SA Water, the Environment Protection Authority, and Adelaide City Council.
