At 3,000 acres in size, Lake Elsinore is the largest natural, freshwater Lake in southern California.

All natural lakes play host to a wide variety of microorganisms, including bacteria, viruses, algae and protozoa. Most of these microorganisms are essential to a healthy aquatic ecosystem, but some are potentially harmful to human health.

Waterborne illnesses caused by certain microorganisms, or germs, can result from body contact with water found in lakes, rivers and streams. Common symptoms of waterborne illnesses include diarrhea, nausea, skin rash, and nose and throat infections.  Find out more about any known risks related to lake.
