The Nevada Harmful Algal Bloom (HAB) Task Force has introduced a new tracking tool and provided safety tips for water recreation as temperatures rise and residents seek relief in the state's lakes, rivers, and reservoirs. The Task Force emphasizes the importance of staying informed about HABs to safely enjoy Nevada's waterbodies.
Cyanobacteria, also known as blue-green algae, are naturally present in surface waters and play a significant role in aquatic ecosystems. However, under certain conditions such as high nutrient levels, warm temperatures, and stagnant water, these organisms can reproduce rapidly and create blooms that may lead to harmful algal blooms (HABs). These blooms pose risks due to factors like nutrient pollution and rising water temperatures.
While not all algae blooms are harmful, some can produce toxins dangerous to humans, animals, and aquatic life. Symptoms of exposure include skin irritation, respiratory issues, gastrointestinal problems, and potentially fatal outcomes for pets. In Nevada, HAB season typically occurs between June and October.
The Nevada HAB Task Force offers several safety tips:
1. **Check for Advisories**: Visit the Office of State Epidemiology HAB Dashboard for any watches, warnings, or dangers.
- A YELLOW advisory level indicates possible hazardous conditions.
- An ORANGE advisory level means the waterbody is unsafe.
- A RED advisory level indicates extremely unsafe conditions.
2. **Learn How to Identify a HAB**: Recognize signs such as scum or discoloration on the water surface. HABs can make water appear like paint or pea soup and often have a distinctive smell.
3. **Avoid Suspected HABs**: Refrain from swimming or engaging in recreational activities in discolored or foul-smelling water with visible algal scum.
4. **Protect Pets and Children**: Keep them away from potentially contaminated water sources.
5. **Monitor Animal Water Sources**: Ensure livestock and other animals do not drink from contaminated sources; contact a veterinarian if they show signs of illness.
6. **Report Suspicious Blooms**: Report suspected HABs to the Nevada Division of Environmental Protection Biological Assessment and Monitoring Branch via email with a photo.
The Nevada HAB Task Force is a multi-agency collaboration formalized in 2024 that includes representatives from various state departments such as Environmental Protection, Health and Human Services, State Parks, Wildlife, and Agriculture. The Task Force utilizes satellite imaging, cyanotoxin analysis, and water quality monitoring practices to provide updates on HAB presence in Nevada.
Jennifer Carr of the Nevada Division of Environmental Protection stated that this collaboration strengthens their ability to detect, monitor, and respond to HABs statewide. Melissa Peek-Bullock emphasized the commitment to safeguarding public health through advanced monitoring technologies. Bob Mergell highlighted the importance of informing visitors about potential risks associated with harmful algal blooms during their recreational activities.
