The gradual lowering (drawdown) of Lake Mulwala is undertaken by Murray–Darling Basin Authority (MDBA) and Goulburn-Murray Water (GMW) to control an invasive waterweed Egeria Densa and undertake necessary infrastructure maintenance.
The lake level will drop 5 metres gradually over 4 to 6 weeks, exposing Egeria Densa weed to the air and winter frosts
The authorities expect to return Lake Mulwala to its regular operating levels by early August.
This practice occurs every 3 to 5 years. In the last 15 years Lake Mulwala has been lowered five times in 2008, 2009, 2011, 2015 and again in 2018.
At Yarrawonga Weir the release was increased to around 12,000 ML/day to facilitate lowering of the Lake.
