Blue-green advisories - 2017


Archives


The advisories have now been taken off our map (12/31/2017), as most blue-green algal blooms occur between May and December in Canada. However, advisories issued over the winter months will be posted as they are issued. Not all provinces publish online lists of blue-green advisories; the list below is of the advisories that were published. Québec, British-Columbia, Saskatchewan, Nova Scotia, PEI, and Yukon, the Northwest Territories and Nunavut do not maintain an online list of blue-green outbreaks in lakes/rivers in their provinces.
