NSP identifies harmful algal bloom at Lahontan

A potential harmful algal bloom has been identified at both Washoe Lake south of Reno and Lahontan Reservoir at the Lahontan State Recreation Area.

According to Nevada State Parks, visitors and their pets to both areas should avoid contact with the water because of potential adverse health effects.

The Interagency HAB Task Force that’s comprised of officials from the Nevada Department of Health and Human Services, the Nevada Division of Environmental Protection, Nevada State Parks and the Nevada Department of Wildlife have been working together to ensure the public is notified to help protect the health of park visitors and their pets.

Furthermore, the NSP said exposure to toxic algae may occur by touching, swallowing or inhaling affected water, and it 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 bodies of water 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. NSP said 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 any of the following are detected:

• the water smells rotten

• large mats or scums are floating on the surface

• the water looks like green paint

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

To protect yourself from toxic algae, the NSP advises people to 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. To learn more about HABs, visit the Center for Disease Control and Prevention website at www.cdc.gov/habs/.
