While the most recent results from water sample testing in Grand Lake has shown a significant decrease in levels of blue green algae (BGA) toxins, the Grand River Dam Authority continues to warn against recreational activities that involve bodily contact with Grand Lake waters.
Those results are from water samples gathered in both the Duck Creek and Horse Creek areas of Grand Lake. According to the GRDA Ecosystems Management Department, that demonstrates a real improvement in the BGA outbreak, however the BGA scums (visible accumulations) found throughout areas around the lake continue to be prevalent and toxic, and need to be avoided.
Though the public is still very much encouraged to enjoy activities in the Grand Lake area, avoidance of bodily contact with Grand Lake waters is still in the public’s best interest. GRDA will continue its daily monitoring and sampling efforts indefinitely, as long as conditions warrant.
