This is the Power Sub Station near the rural city of Kerang... that supplies most of the power to the north west of the state.
It had been sandbagged to prevent the power being cut during the flood crisis but due to the increased amounts of flow a levee bank was rapidly built around the site as the existing sandbag walls were being overtopped by the water height.
This scenario has continued to occur within many townships as as the floodwaters continue to surge north... Levee banks neglegted through years of drought are either leaking or giving way or simply not high enough to withstand the unprecedented levels of water.
Satellite imagery below will give you an idea of just how much water is travelling through country..
