WORTHINGTON — In testing algae blooms in Lake Okabena, the Okabena-Ocheda Watershed District detected high levels of the microcystins toxin Monday, Aug. 3 and Tuesday, Aug. 4 at Sailboard Beach.
According to OOWD Administrator Dan Livdahl, tests on Tuesday at Centennial Park Beach showed no toxins, which he said makes sense because there was no algae bloom along that beach Monday or Tuesday.
The city of Worthington will post caution signs Tuesday at all of the boat landings, Centennial and Sailboard Beach, which will remain up until further notice. Signs will read:
*CAUTION*LAKE OKABENA VISITORS & RESIDENTS
Harmful Algae Blooms
May Be Present
Algae Bloom Toxins Can Be
HARMFUL TO PEOPLE AND PETS
Algae blooms had been absent in Lake Okabena for the last two years, until drought and hot temperatures brought them back this summer.
OOWD has been collecting one-liter samples and testing one milliliter of each, to determine whether or not the microcystins toxin is present.
The public is encouraged to avoid getting in the water near algae blooms. Microcystin algae may cause skin irritation upon contact and can be fatal if swallowed.
