E. Coli Contamination Closes Popular South Lake Tahoe Swimming Area

SOUTH LAKE TAHOE, Calif. – A popular stretch of Lake Tahoe’s South Shore has been temporarily flagged for high levels of E. coli bacteria, prompting officials to urge swimmers, paddlers, and beachgoers to avoid the area near Camp Richardson Resort.

What Happened

Recent water quality testing conducted at Camp Richardson revealed elevated concentrations of Escherichia coli (E. coli) in shoreline waters. In response, the resort initiated a sewer line inspection, quickly located a leak, and has begun repairs.

Although no illnesses have been reported, officials are advising the public to steer clear of recreational waters between Jameson Beach and the Valhalla Boathouse as a precaution.

What’s Affected—and What’s Not

• Impacted Area: The section of shoreline adjacent to Camp Richardson Resort is under active advisory.

• Safe Zones: Water samples taken east and west of the primary site, including near Jameson Beach and Valhalla Boathouse, did not exceed California state standards and remain open.

• Rest of Lake Tahoe: There are no indications that other parts of Lake Tahoe have been affected.

Who’s Responding

Multiple agencies are coordinating the response and cleanup effort, including:

• USDA Forest Service – Lake Tahoe Basin Management Unit

• Camp Richardson Resort

• El Dorado County Environmental Management

• Lahontan Regional Water Quality Control Board

• Tahoe Regional Planning Agency

They’re working together to:

• Post warning signs for swimmers, boaters, and paddlers

• Investigate the source of the contamination

• Conduct daily water sampling in and around the affected zone

• Determine when the area is safe to reopen

What You Should Know About E. Coli

E. coli is a naturally occurring bacteria found in the intestines of humans and animals, but certain strains can cause illness when ingested or introduced through open wounds.

The Centers for Disease Control and Prevention (CDC) recommends:

• Avoid swallowing lake or pool water

• Wash hands thoroughly after water contact

• Monitor for symptoms such as stomach cramps, diarrhea, or fever after exposure

More tips on prevention can be found on the CDC’s website.
