Streamflows - May 2007
The widespread distribution of heavy rainfall throughout the State in May resulted in a dramatic improvement in streamflows, particularly in southwest and east Victoria. (see map, graphs, and table)
The combination of wet weather and wetter soils has resulted in an increase in runoff in most areas of the State, with the exception being Central and North Central Victoria, and parts of West and East Gippsland.
By the end of the month, 10 out of the 28 representative stations recorded flows below 10% of the long-term average, covering around 45% of the State. Of these, 5 stations recorded no flow conditions, compared with 10 in April. These included stations in the Loddon and lower Avoca basins (North Central district) and the lower Moorabool (Central district).
In contrast, six stations recorded flows exceeding 100% of the long-term average for May. These included the Hopkins River at Wickliffe and the Wimmera River at Glenwylln.
At the end of May, flow at 16 representative stations was higher than flow during the 1982/83 drought. Twenty-two stations had flows higher than the minimum recorded in May.
