Algae Update at Grand Lake

Langley, OK – Conditions continue to improve at NE Okla. lake

LANGLEY, Okla. (AP) The Grand River Dam Authority says water conditions at Grand Lake have improved greatly since a "no bodily contact" warning that was issued because of the presence of blue green algae was canceled.

GRDA officials say the agency's Ecosystems Management Department continues to monitor and perform tests since the algae outbreak was confirmed at the northeast Oklahoma lake in late June. Department director Darrell Townsend says the most recent tests have been negative for toxins.

Blue green algae are microscopic organisms that are naturally present in lakes and streams. Most aren't toxic, but some algae blooms can produce toxins harmful to humans and animals.

Townsend says officials still want the public to avoid areas of the water where blue green algae scums appear to be present.
