High blue-green algae toxins detected in Alpine County lakes

The levels of toxins associated with blooms of blue-green algae have reached above the "danger" level at Red Lake in Alpine Count, and at the "warning" level at Indian Creek Reservoir.

The Alpine County Health Department has been working with The Lahontan Regional Water Quality Control Board, California Department of Fish and Wildlife (Red Lake), South Tahoe Public Utility District (Indian Creek Reservoir), and the Alpine Watershed Group (AWG) in determining these levels.

Both Red Lake and Indian Creek Reservoir have been posted with the appropriate warning signs in effect until further notice. Ongoing testing will be conducted on a regular basis.

"My prediction is that conditions will get worse before they get better,: said Alpine County Health Officer Dr. Richard Johnson.

Potential symptoms in dogs following exposure to blue-green algae toxins can include lethargy, difficulty breathing, salivation, vomiting, urination, diarrhea, or convulsions leading to death, said Dr Johnson.

"The unexplained death of a dog after contact with contaminated water is often a sentinel event which alerts officials to the potential of a toxic bloom. People can experience eye irritation, skin rash, mouth ulcers, vomiting, diarrhea, and cold or flu-like symptoms, with impacts to the liver. Dogs and children are most likely to be affected because of their smaller body size and tendency to stay in the water for longer periods. While there is no antidote for exposures, persons should see their physician and those with pets which may have been exposed should go to their veterinarian for supportive care. Livestock who are drinking contaminated water can also suffer fatal consequences," said Dr. Johnson in a press released.
