Algae blooms occur each year at Shawnigan Lake and they are a somewhat unpredictable occurrence that is influenced by sunlight, amount of nutrients and warmer temperatures.  Some years, the effect on the water quality is more noticeable, as it is this year.  Apart from taste and odour concerns there are no known health concerns related to these algae blooms.

To confirm the types of algae present in the lake water a sample was taken this morning (May 16) and sent to a laboratory for analysis.  The laboratory will also be analysing for metals in the water.  Results from these tests are expected in 1-2 weeks.  A sample for metals and nutrients was taken on May 4 and results from this sample is expected shortly.  Both of the results of these tests will be posted on the website.

The system water is sampled each week for bacterial contamination (E. Coli and total coliforms) and past results for these routine tests have been negative for bacterial contamination.
