PRESQUE ISLE COUNTY, Mich., (WPBN/WGUT) -- District Health Department No. 4 is continuing to issue a public health awareness bulletin for Black Lake near Onaway after algae blooms were found on the lake for a second time.
The bulletin was first issued on September 15 after a bloom was found in the lake near Silver Beach Road and tested above 10 ug/L of microcystin.
Health officials said the current blooms are now toxin-producing after the testing results on September 23.
Out of an abundance of caution, District Health Department No. 4 wants residents and visitors to be aware of the algal bloom on Black Lake. Advice may change based on additional testing or as more information becomes available. Also, the amount of algae in the lake can change quickly.
What should I do if I see a HAB?
- Stay out of water that may have a HAB. Enter and swim in nonaffected areas of the lake.
- Do not let your children or pets play in HAB debris on the shore.
- Never swallow any lake or river water, whether you see HABs or not.
- Do not let pets lick HAB material from their fur or eat HAB material.
- Do not drink or cook with lake water.
- See a doctor if you or your children might be ill from HAB toxins, or call Poison Control at 1-800-222-1222. If your pet appears ill, contact your veterinarian.
- HABs should be reported to EGLE by calling the Environmental Assistance Center at 1-800-662-9278 or emailing AlgaeBloom@michigan.gov.
