Description
Due to natural soil characteristics and proximity to major urban centres, the Pigeon Lake watershed has undergone significant urban and rural development in the past decades. In recent years, occurrences of significant blue-green algae (cyanobacteria) blooms have been documented at Pigeon Lake. The following report includes an overview of cyanobacterial ecology and provides a list of in-lake and watershed management options for control of nuisance blue-green blooms and outlines the benefits, disadvantages and applicability to Pigeon Lake. While several options are available for stakeholders to pursue, it is important that a cost-benefit analysis be conducted beforehand and that stakeholders ensure that all applicable permits and approvals be obtained.
