The Logan County Health District is looking into reports of potential harmful algal blooms at Indian Lake.
The health department has received reports from the Ohio Department of Health regarding satellite imagery of Indian Lake. The imagery suggests the presence of cyanobacteria, microorganisms capable of forming harmful algal blooms (HABs). These blooms pose risks to both humans and animals and can detrimentally affect the aquatic environment.
The potential for harmful algal blooms is most serious in the area of Oldfield Beach and on the north side of the lake, according to satellite imagery.
The most recent satellite imagery, captured on May 30, 2024, reveals cyanobacteria coverage estimated to affect 10-50% of the lake, with an increased density compared to previous observations. Notably, the imagery indicates potential HABs for the fourth consecutive summer, with 2024 showing signs approximately two weeks earlier than in 2023.
While no animal or human illnesses related to these blooms have been reported to the Logan County Health District in previous years, the presence of cyanobacteria warrants community awareness and precautionary measures.
HABs can affect individuals through various means of contact, including drinking or swallowing contaminated water, skin contact, and inhalation. The health effects of exposure can range from mild discomfort to severe illness and even death. Symptoms may include gastrointestinal issues, skin rashes, respiratory problems, and neurological effects.
In the event of contact with HABs-contaminated water, individuals are advised to promptly rinse off with clean, fresh water. Anyone experiencing symptoms associated with HABs exposure should seek medical attention, and healthcare providers are encouraged to notify their local health district if they suspect a HABs-related illness.
Furthermore, pet owners are urged to be vigilant, as animals can also suffer adverse health effects from exposure to HABs-contaminated water. Signs of illness in pets should prompt immediate veterinary care, and thorough rinsing with clean water is recommended to minimize toxin ingestion.
As the Logan County Health District continues to monitor the situation, residents are advised to stay informed and take necessary precautions to mitigate the risks associated with harmful algal blooms.
