The following press release was recently issued by the Nine Mile Creek Watershed District.
Edina, Minnesota, Aug. 26, 2020 – The public should avoid contact with the water in Lake Cornelia and Lake Edina. The water contains blue-green algae at levels that could potentially cause harm. People and pets should avoid all contact with the water, scum, foam or algae.
Updated analyses of water samples from Lake Cornelia and Lake Edina show that blue-green algae numbers exceed the World Health Organization (WHO) threshold for moderate probability of adverse health effects. High levels of blue-green algae are a concern because this type of algae can produce algal toxins, which can pose a health threat for pets and people when concentrations become high enough. Algal toxin testing has not occurred on either waterbody. The District will collect another sample from Lake Cornelia and Lake Edina in two weeks. The District will release updated information on algal levels on this page when it is available following the sampling event.
Now is the time of year where blue-green algae blooms start to appear throughout the metro area. Always remember, when in doubt, best keep out. The Nine Mile Creek Watershed District is on the look-out for suspected blue-green algae blooms in the lakes that are part of its yearly monitoring program. If you suspect a blue-green algae bloom, you can email pictures of the suspected bloom to email@example.com.
