GRDA’s testing shows…Grand Lake conditions continue improvement

Langley – In the two weeks since the Grand River Dam Authority removed its “no bodily contact” warning for Grand Lake waters (originally issued because of Blue Green Algae) water conditions have continued to improve greatly.

That is the word from the GRDA Ecosystems Management Department. The department has continued monitoring and testing efforts since the Blue Green Algae (BGA) outbreak was confirmed in late June.

“Our most recent tests have been negative for toxins,” said GRDA Ecosystems Management Director Dr. Darrell Townsend. “We have seen steady improvement in the conditions since early July.”

On July 13, after testing showed a significant decrease in BGA toxin levels, GRDA removed all its warnings against bodily contact with lake waters.

“At this point, we are simply asking the public to remain vigilant and avoid areas of the water where BGA scums appear to be present,” said Townsend.
