It’s hardly the kind of publicity one would like to see for Sandy Lake.<\/p>\n

The now confirmed, unusually late bloom of BGA<\/a> (Blue-Green Algae or Cyanobacteria) in Sandy Lake, besides being another warning sign<\/a> that we can’t take the seemingly near-pristine state of Sandy Lake for granted, appears to be among the latest if not the latest occurring bloom yet reported for Nova Scotia*.<\/p>\n

Unusually late occurrence of a Dolichospermum bloom in a Nova Scotia lake<\/strong><\/em>

Conclude the authors, “An early-warning monitoring framework implemented over a longer seasonal period (April \u2013 November) is recommended for Sandy Lake and other urban lakes in Nova Scotia.”<\/p>\n

The authors express appreciation to “regular Sandy Lake Association volunteers, Ed Glover, Derek Sarty and Bruce S, who watch over the lake”, one of whom viewed the bloom on Nov. 6, 2024 and took a sample of it.\u00a0 Indeed, it’s a good illustration of the value of “citizen science”.<\/p>\n

*A NS Gov. web page<\/a> describes the Blue Green Algae season as May to October. A NS Gov document listing “Reported blue-green algae in previous years<\/a>” cites 232 occurrences in NS Lakes 2009 to 2023; only 4 of those were in October, 1 in Nov., that for Lochaber Lake in Antigonish in 2014 <\/small><\/p>\n","protected":false},"excerpt":{"rendered":"
