Funding to help Kyogle fight off algae

KYOGLE Council have expressed their pleasure at receiving State Government funding to install a solar-powered device on its new water supply storage dam to prevent algal blooms.

The $69,360 grant under the government's Building Resilience to Climate Change Program will allow the council to install a 'mixer' to destratify the water in the million dollar dam being built off-stream of the Richmond River at Kyogle.

Council's Executive Manager Urban and Assets Graham Kennett said increased temperatures associated with climate change had the potential to increase the risk of toxic algal blooms occurring in storage dams.

"When water is stored in a dam of this kind, without a regular flow and turnover, the stored water forms layers of different temperature and oxygen levels. This is called stratification," he said.

"This stratification provides the ideal environment for the growth and reproduction of algae species, including toxic blue-green algae."

Mr Kennett said the mixer was designed to continuously move the water around, resulting in a more uniform temperature and dissolved oxygen levels in the stored water.

"This effectively destratifies the storage and breaks down the environment that the algae needs to thrive," he said.

News of the $69,360 grant was announced by Lismore MP Thomas George.

Mr George said the State Government's Building Resilience to Climate Change Program supported local action to deal with climate change risks and vulnerabilities.
