Potential harmful algal bloom identified in Washoe Lake

Scientists sampling surface waters at Washoe Lake State Park have identified a potential harmful algal bloom along the shoreline of the lake, according to a release from the state parks department.

Exposure to toxic algae can occur by touching, swallowing, or inhaling affected water, and can lead to mild or potentially serious health issues. Children and pets are especially at risk. Visitors and their pets are urged to avoid swimming in the lake water until further notice. The lake will remain open for motorized boating as well as paddling.

Algal blooms can last for days or weeks and toxins can last for days after the bloom. They can occur at any time of the year but are most common in the summer – when the water is warm and stagnant. A HAB may be present if: 

• The water smells rotten

• Large mats or scums are floating on the surface

• The water looks like green paint

• There are bright colors like blue, green, white, brown, or red

To protect yourself from toxic algae, avoid recreating (wading, swimming, jet-skiing, or water skiing) in water containing possible algal blooms. Keep children and pets away from the water. Do not drink, cook, or wash dishes with the affected water. If you come in contact with the water or the algal scum, wash the area thoroughly with clean water from a safe source.

Fish can collect  algal toxins in their bodies, but fish in Nevada likely have lower levels because blooms are irregular. If you decide to eat a fish you catch during a bloom, wash it carefully with clean water and only eat the fillets. Throw skin and internal organs in the trash, which may have higher levels of algal toxins.

Individuals who believe they may be experiencing symptoms of exposure to algal toxins should contact their local health-care provider or contact the Poison Control Center: 1-800-222-1222.
