Make room for algal blooms

Washington's lakes and rivers are entering algae season, raising alarms about harmful algal blooms due to climate change and nutrient pollution. These blooms can disrupt ecosystems and pose serious health risks to humans and animals. Residents are urged to avoid water with visible algae and stay informed about safety warnings. The only reliable way to detect harmful toxins is through laboratory testing, as some toxic blooms may not be visibly apparent. The Washington State Department of Ecology supports local initiatives through grants aimed at managing excessive freshwater algae growth.

Nutrient sources such as fertilizer runoff and failing septic systems contribute to the problem, and unpredictable weather can trigger blooms even in normally stable nutrient levels. Awareness of the characteristics of toxic algae can help residents stay safe. Prompt action is advised if exposure occurs, including rinsing off and seeking medical attention.
