Water quality results at this site

Between 13 and 20 samples will be collected during the annual summer bathing season from November to early April. Purple vertical bars show the bacterial count measured in the water on particular days. These are single sample counts.

Note the logarithmic scale of the bacterial indicator axis. It is not a linear graph where the intervals are unchanged up the scale.

A bathing site is considered safe for swimming unless two consecutive sample counts for marine water are more than the Action Limit of 280 enterococci/100ml at beach sites or when the single sample count for freshwater is more than 550 E. coli /100ml.

Should single sample counts be greater than the Action Limit, this indicates that the maximum recommended value for safe swimming has been exceeded and additional sampling, and investigations may be initiated.

The Medical Officer of Health advises users "that bacterial counts are high after heavy rainfall. Recreational use should be reduced for two-three days after heavy rainfall".
