February 2009 - Catchment Impact Table
Around 30% of Melbourne's catchments was damaged by fire. This was mostly centred on the O'Shannassy and Maroondah catchments.
|Catchment||Fire affected||Area burnt
|Share of total reservoir inflow|
|Reservoirs with catchment|
|Upper Yarra||Yes||About 2% burnt||19%|
|Maroondah||Yes||About 75% burnt||12%|
|O'Shannassy||Yes||About 93% burnt||12%|
|Yan Yean||No||None||2% (not in supply)|
|Tarago||Yes||About 50% burnt||Nil (not used for Melbourne's water supply)|
|Reservoirs with no catchment|
|Cardinia||No||N/A (no catchment)||Nil|
|Sugarloaf||No||N/A (no catchment)||12%*|
|Greenvale||No||N/A (no catchment)||Nil|
|Silvan||No||N/A (no catchment)||7%#|
|Graceburn Creek||Yes||About 100% burnt||Run-off to Maroondah Reservoir|
|Wallaby Creek||Yes||About 100% burnt||Run-off to Yan Yean Reservoir|
|Armstrong Creek||Yes||About 100% burnt||Run-off to Silvan Reservoir|
|Coranderrk Creek||Yes||Less than 2% burnt||Run-off to Silvan Reservoir|
|McMahons Creek||No||None||Run-off to Silvan Reservoir|
|Starvation Creek||No||None||Run-off to Silvan Reservoir|
Percentages are calculated from the annual average inflow (run-off) into our reservoirs from 1997-2008.
* Sugarloaf inflow is from the Maroondah aqueduct and Yarra River.
# Silvan inflow is from small catchments (see above). This accounts for 7% of our total reservoir inflow.
