Navigation Warning - Lake Mulwala and upstream sections of the Murray and Ovens River and tributaries - Lowering of lake
LAKE MULWALA AND UPSTREAM SECTIONS OF THE MURRAY AND OVENS RIVERS AND TRIBUTARIES
Lowering of lake level
From Monday 30 April to August 2018
Roads and Maritime Services advise vessel operators that Lake Mulwala will be lowered by about 3.5 metres this winter to facilitate works around the lake foreshore and weed control under an inter-agency program the involving the Murray–Darling Basin Authority and Goulburn-Murray Water.
Lake levels will start to fall slowly from 30 April, and by about 70cm until mid-May, when the irrigation season ends. The draw-down will then accelerate until Lake Mulwala is 3.5 metres lower than normal where this level will be held until mid-July when refilling will start.
The lowering will affect tributaries upstream of the lake and expose the lake flats, which will be muddy, reducing amenity, access and the ability to launch boats from the boat ramps. Vessel operators may still be able to boat and fish in the main river channel that runs through the lake, but will need to launch vessels upstream.
Caution should be taken when navigating in this area due to the heightened risk of unmarked/submerged hazards and reduced water levels.
Large vessels are advised to consider their voyage and plan appropriately.
