SNOHOMISH — Blackmans Lake has a potentially toxic bloom of blue-green algae, according to a press release from the City of Snohomish.
Snohomish County staff noticed algae scum at the public boat launch in Ferguson Park on Monday. Algae scum is typically found along shorelines and looks like green, blue or white paint on the water’s surface.
City officials advised visitors of the following guidelines:
• Do not swim in the lake;
• Do not drink lake water;
• Keep pets away from the lake;
• Clean fish well and discard guts;
• Avoid areas of scum when boating.
Humans and pets exposed to toxic algae can experience naseau, vomiting and diarrhea, according to the Centers for Disease Control and Prevention.
Wildlife such as waterfowl, otters and deer might also be affected by toxic algae, especially if they are consuming water with high concentrations of scum.
If people exhibit symptoms of toxic poisoning, city officials said people should call their health care provider.
