Blue-Green Algae Warning at Lake Ralphine (Santa Rosa Recreation and Parks)
A blue-green algae warning has been issued for Lake Ralphine in Santa Rosa’s Howarth Park.
The public is being asked to stay out of Lake Ralphine along with their pets due to the algae or cyanobacteria detected. Weekend boat rentals have also been canceled because if ingested, the algae can cause toxic substances that attack internal organs, resulting in severe illness or death.
Blue-green algae has been on the rise in California and the west due to warm temperatures and high carbon dioxide levels in the atmosphere.
