Description

Signage at the impoundment indicates that there are periodic problems with blue-green algae blooms. When present, people are advised not to swim nor let any pets swim in or drink any water from the pond or river! Blue-green algae produce toxins which are dangerous/fatal to humans and pets!

"If the water is cloudy, looks like green paint or pea soup, or has floating scum layer or floating clumps ..."

These events are most likely when summer temperatures have warmed the millpond.

If you boat during these times, do your best to minimize contact with the water, and make certain to bathe/rinse yourself and any wet gear (clothing, PFD, etc) as soon as possible!

See WIDNR Website for more information. (Several tabbed pages of info to read!)
