Over the weekend, the post claimed that a dog died shortly after swimming.The post’s author stated that the dog displayed symptoms consistent with toxic algae exposure before passing away just 30 minutes after entering the water.
Toxic algae, or harmful algal blooms (HABs), occur when certain algae grow rapidly due to factors like nutrient pollution, warm temperatures, and stagnant water. These blooms produce toxins harmful to people, animals, and the environment. Dogs are especially at risk, as exposure to cyanobacteria can lead to severe illness or death. The severity of the illness can range from mild symptoms to fatal outcomes, occurring from minutes to weeks after exposure.
In response to the viral post, Sierra Daily News reached out to local authorities, including Lassen County Public Health and Environmental Services, to inquire about the water quality at Eagle Lake. However, it was learned that the county does not test or monitor local recreational water bodies; that responsibility falls to the state water board.
The Harmful Algal Bloom Coordinator for the Lahontan Water Board Office confirmed that the dog’s death will be investigated. Water samples will be collected to determine whether a harmful algal bloom was the probable cause of death. While the investigation is ongoing, it has been recommended that cautionary signage be posted at Eagle Lake, specifically at Gallatin Beach near Camp Ronald McDonald, where the incident reportedly occurred.
The Eagle Lake Fishing Information and Network, an organization active on the water, mentioned that there could be the potential for an algal bloom. However, they noted that over the past week, water clarity has improved compared to earlier weeks, though the water remains somewhat cloudy. They also mentioned that it has been a very mild season overall for algae.
The National Oceanic and Atmospheric Administration (NOAA) satellite imaging indicated algae in the northern part of the lake, which is common and often attributed to grazing cattle in the area.
We will continue to follow up on this developing story as more information becomes available.
