NPS Warns of Deadly Algae in Lake Mead
23 Mar
Summary
- Harmful algal bloom detected in Lake Mead's Government Wash.
- Ingestion of toxins can cause severe illness or death in pets.
- Microcystis bacteria, producing toxins, is common in blooms.
A harmful algal bloom (HAB) containing potentially fatal toxins has been detected in Lake Mead's Government Wash, according to a National Park Service (NPS) alert. The bloom poses a significant risk to both children and pets if the contaminated water is ingested. Symptoms of exposure can range from nausea and vomiting to severe organ damage, seizures, and even death.
Microcystis, a type of blue-green bacteria, is identified as the species commonly behind these outbreaks. These bacteria produce toxins that can harm vital organs upon ingestion. The NPS strongly advises visitors to keep pets on leashes and away from affected waters, urging immediate veterinary attention for any animals showing signs of illness after exposure.
While HABs typically occur between August and December, they can form outside this period under favorable conditions like calm, warm, and sunny weather. The NPS also noted recent closures of several Lake Mead hiking trails due to dangerously hot conditions, reminding visitors to stay hydrated and be aware of their limits.
