Yarra Bay: Faecal coliform compliance with swimming guidelines has ranged from 71% to 100% over the last five years. Enterococci compliance with swimming guidelines has been more variable, ranging from 57% to 100%over the last five years. Faecal coliform levels often exceeded the median guideline limit after light rain in the previous 24 hours. Enterococci levels often exceeded the median guideline limit after light rain and frequently exceeded the median guideline limit after five millimetres of rain or more in the previous 24 hours.
Frenchmans Bay: Faecal coliform compliance with swimming guidelines has ranged from 71% to 100% over the last five years. Enterococci compliance with swimming guidelines has been more variable, ranging from 56% to 100% in the last five years. Bacterial densities occasionally exceeded median guideline limits in response to no rain, indicating a possible dry-weather contamination problem. Faecal coliform densities often exceeded the median guideline limit in response to five millimeters light rain and enterococci densities regularly exceeded the median guideline limit after light rain in the previous 24 hours.
Congwong Bay: With the exception of winter 2007, faecal coliform levels have complied 100% of the time with swimming guidelines over the last five years. Enterococci compliance with swimming guidelines has been more variable, ranging from 81% to 100% over the last five years. Bacterial densities increased slightly with increasing rainfall, with faecal coliform densities occasionally exceeding the median guideline limits after light rain in the previous 24 hours. Enterococci densities often exceeded the median guideline limits in response to five millimetres of rain or more in the previous 24 hours.
Litte Bay: Monitoring at Little Bay began in December 2006. Since then faecal coliform compliance has ranged from 94% to 100% and enterococci compliance has ranged from 91% to 100%. Bacterial densities generally increased with increasing rainfall. Faecal coliform levels often exceeded the median guideline limit after ten millimetres of rain or more in the previous 24 hours, and enterococci levels regularly exceeded the median guideline limit in response to ten millimetres of rain or more in the previous 24 hours.
Malabar: Faecal coliform compliance has ranged from 74% to 100% over the last five years. Enterococci compliance has been more variable, ranging from 29% to 100% over the last five years. Bacterial densities increased with increasing rainfall and occasionally exceeded the median guideline limits after little or no rainfall, indicating a dry-weather contamination problem. Enterococci levels usually exceeded the median guideline limit in response to five millimetres of rain or more in the previous 24 hours.
