WATER CONTACT ADVISORY
A water contact advisory associated with Harmful Algal Blooms has been issued for Devils Lake due to elevated levels of the toxin Microcystin. This toxin is produced by a type of blue-green algae called Microcystis currently growing in the lake in high numbers. The recreational limit for the toxin is 10 parts per billion (ppb) with many sites reporting levels above 25 parts per billion. Areas of highest blue-green algae density are typically the most affected, however the toxin has have been found lake wide to varying degrees. Also please note that conditions can change rapidly as the blue-green algae are circulated around the lake by wind and wave action, so toxin levels where they may have been less elevated can increase rapidly.
During this water contact advisory:
Do not drink the lake water (Please note that the Devils Lake State Campground does not use lake water for drinking, so their water as well as all city water is safe).
Avoid swimming or waterskiing in areas of scum or where toxins are known to be present.
Keep pets away
Clean fish well and discard guts
Avoid areas of scum when boating
Call your doctor or veterinarian if you or your animals have sudden or unexplained sickness or signs of poisoning.
