The Perth Hills bushfire in January 2005 impacted more than 27,000 hectares of the region's drinking water catchment area. The effect this bushfire had on the water quality varied throughout the affected catchments, with increased sediment load observed in areas with steep slopes, higher rainfall recorded, and an increase in fire intensity. Turbidity was also observed to have risen at most sites.
