Once a blue-green algae bloom is reported to the Regional Office of the Department of Environment and Local Government, the advisory is posted below.
The advisory will then remain on the list indefinitely. Although each summer the area of water indicated may not have blue-green algae bloom, they are left on the list for visitors to be aware that they could possibly recur since the area has had blue-green algae blooms in the past. Future sampling of the area will not be undertaken to rescind any advisories due to the unpredictability of blue-green algae blooms.
The Office of the Chief Medical Officer of Health encourages the public to be active and enjoy the outdoors but be aware that blue-green algal blooms can be unpredictable. Advisories are issued to inform local recreational water users to help make informed decisions on water use in the affected area and to be more aware to look for the formation of highly visible blooms and scum, which pose the most risk.
