Streamflows - September 2010
High rainfall in the first week of September, falling on already wet catchments, resulted in widespread flooding, particularly in the Avoca, Campaspe, Goulburn, Loddon, Ovens and Wimmera rivers. Despite additional rain in the second week, streamflows started to recede as flood peaks moved downstream. There was little significant rainfall across Victoria throughout the rest of the September, and consequently streamflows had declined by the end of the month.
Of the 28 representative streamflow gauging stations, only one station in the Upper Ovens catchment recorded flows above the long-term September average at the end of the month. A further eight stations in northeast Victoria and Gippsland recorded flows between 40 and 80% of the long-term September average.
Stations on the Avoca, Genoa and Moorabool rivers recorded flows less than 10% of the long-term September average at the end of the month. The remaining 15 stations across Victoria recorded flows between 10 and 40% of the September average.
End-of-month flow was higher than the historical minimum for September at all 28 stations.
