The Nevada Harmful Algal Bloom (HAB) Task Force is urging the public to be aware of the dangers posed by harmful algal blooms. According to Weston Fettgather, an environmental scientist with the Nevada Division of Environmental Protection, one of the task force's main goals is to provide clear and accessible information to those who enjoy Nevada's waterbodies. "By doing so, we hope to empower the public to take appropriate precautions to protect themselves, their families, and their pets during harmful algal blooms," said Fettgather.
Cyanobacteria, also known as blue-green algae, are naturally present in Nevada's surface waters. They play a crucial role in aquatic food webs and biochemical processes. However, under certain conditions such as high nutrients, warm temperatures, and stagnant water, these organisms can reproduce rapidly and create a bloom that may lead to a HAB.
Not all algal blooms are harmful; however, some can produce toxins dangerous to humans and animals. These toxins cannot be identified without testing. Exposure symptoms include skin irritation, respiratory issues, gastrointestinal problems, and can be fatal for pets like dogs. In Nevada, HAB season typically occurs from June through October.
The task force provides several safety tips:
- Check for advisories at habs.ndep.nv.gov before heading out.
- Learn how to identify a HAB.
- Avoid suspected HABs.
- Protect pets and children from contaminated water.
- Monitor animal water sources.
- Report suspicious blooms using the online reporting tool provided by NDEP’s Biological Assessment and Monitoring Branch.

The Nevada HAB Task Force was initiated in 2019 and officially formalized in 2023. It aims to combat challenges posed by harmful algal blooms through advanced technologies and community outreach. The task force partners with various state departments including the Nevada Division of Environmental Protection and federal partners.
