Some species of these algae can produce toxins, posing a risk to humans and pets. The department said to call your veterinarian or doctor immediately if you become sick after ingesting or coming in contact with algae. … The departments said they will provide updates through a routine water monitoring program that conducts site visits at this waterway.
