Lake Mulwala to be emptied

March 28, 2018

A lowered Lake Mulwala this winter will again provide a unique spectacle.

Lake Mulwala will be lowered by about 3.5 metres this winter to facilitate works around the lake foreshore and to control weed.

After much speculation in recent months Murray–Darling Basin Authority (MDBA) and Goulburn-Murray Water (GMW) confirmed last Friday the lake would start to be emptied at the end of April and be full again by early August.
Authorities have committed to lowering the lake every few years to mainly control the invasive aquatic weed, Egeria densa.
In the last 10 years Lake Mulwala has been lowered four times in 2008, 2009, 2011 and again in 2015.
MDBA’s head of River Management, Andrew Reynolds said the lake will be back to its usual level in early August.
“Lake levels will start to fall slowly from 30 April by about 70cm until mid-May when the irrigation season ends,” Mr Reynolds said
“Once we are sure that irrigation water delivery to customers is finished for the year, we’ll accelerate the drawdown until Lake Mulwala is 3.5 metres lower than normal—a level we expect to hold until mid-July when refilling will start,” Mr Reynolds said.
“The lowering will expose the lake flats, which will be muddy, reducing amenity, access and the ability to launch boats from the boat ramps. People will still be able to boat and fish in the main river channel that runs through the lake but will need to launch their boats upstream. 
“Along with GMW we have been talking with community members, council and tourism operators to try to minimise and limit disruptions.”
