Cyanobacteria, also referred to as blue-green algae (BGA), are common photosynthetic bacterial inhabitants of Alberta’s surface waters. Under favorable conditions, such as warm water and high nutrient content, these bacteria can form nuisance “blooms”. Blooms are of importance to public health because some genera have the capability of producing very potent toxins, such as neurotoxins, hepatotoxins, and lipopolysaccharide endotoxins.
This tool is designed to allow you to explore the historical data related to monitoring for cyanobacterial blooms at public recreational beaches on Alberta Lakes. For current cyanobacterial bloom advisories please visit Alberta Health Services site for an up to date listing. More information on cyanobacteria is available in the AHS FAQs.
Clicking the charts' titles will colour the circles based on that metric.
To learn more about a metric simply hover the mouse over its title.
The light grey background bars represent the distribution of the entire dataset while coloured and dark grey bars display data for the selected year and any filters you have applied. Add filters or select a year by clicking on the charts.
Any other selection will order the beaches by the median value for that metric.
Selecting Lake Name will group the beaches by their respective lakes.
Selecting Geography will display the beaches in their geographic location.
Each circle represents a beach. The size of the circle indicates the number of tests. Small grey dots indicate no testing was performed in the selected year. Otherwise, the colour represents the median value for the year with the selected distribution chart (above) as your legend.
Clicking on a beach will reveal a detailed breakdown of the beach's sampling results for the selected year.
Hovering over the dots will display the sample results for that test.
Right clicking a beach will display a map showing the location where the sample was collected.
