Lower Lakes water levels to drop slightly
Date posted: 16 February 2018
Water levels along the Lower Lakes and below Lock 1 will drop slightly during late February and March to improve habitat for threatened frogs and fish.
Department of Environment, Water and Natural Resources (DEWNR) Water Resource Operations Manager Jarrod Eaton said the slight drop in water level is within normal operating range and should not impact local irrigators.
“The water level will drop to between 0.50 to 0.55m AHD, but may experience daily changes due to the wind,” Mr Eaton said.
“We encourage irrigators to regularly check the weather forecast before pumping from Lake Albert and Lake Alexandrina.”
The slight lowering of water level restores the natural summer-early autumn drying pattern in wetlands that fringe the Lower Lakes.
Mr Eaton said that it will help stimulate vegetation growth as well as fish and frog breeding going into the wetter conditions of winter and spring.
“During the lowering environmental water will be provided by the Commonwealth Environmental Water Holder to deliver continuous, small freshwater releases to the Coorong to assist in managing the Coorong’s salinity and support fish movement,” Mr Eaton said.
Water levels are planned to increase again in April.
DEWNR is working with the Commonwealth Environmental Water Holder and the Murray-Darling Basin Authority to deliver the project.
