Make room for algal blooms

As Washington's lakes and rivers enter algae season, harmful algal blooms pose increasing challenges due to shifting climate patterns and nutrient pollution. These blooms can disrupt ecosystems and produce toxins harmful to human and animal health. Residents are urged to avoid water exhibiting signs of algae, including slimy scum and unusual colors, and to heed local health advisories. Laboratory testing remains the only reliable method for identifying toxins in algal blooms. The Washington State Department of Ecology provides annual grants to local jurisdictions to manage excessive algae growth, emphasizing the importance of community involvement.

Factors contributing to these blooms include nutrient runoff from fertilizers and urban areas. Local managers decide when to close affected water bodies based on state health guidelines. Awareness and precautionary measures are crucial for protecting public health during this season.
