The following press release was recently issued by the Nine Mile Creek Watershed District.
Edina, Minn., Sept. 11, 2020 - The public is advised to have no contact with the water in Arrowhead Lake.
Water monitoring recently conducted at Arrowhead Lake by the Nine Mile Creek Watershed District (NMCWD) indicated the potential for high concentrations of blue-green algae. 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.
NMCWD will be evaluating samples from the lake to determine the type and number of blue-green algae. Until results are available, NMCWD is urging people and pets to stay out of the water. The NMCWD will release updated information on blue-green algae levels when it is available.
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 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 firstname.lastname@example.org.
