Tahoe’s clarity report card just came out, yet two sewage spills occurring within less than two weeks of each other have minds on murkier matters. A private contractor working for Caltrans on Highway 28 near Gar Woods struck a North Tahoe Public Utility District’s main sewer export pipeline the morning of July 18. This sent an estimated 85,000 gallons of raw sewage into Carnelian Bay. The spill closed beaches and a myriad of health advisories ensued, warning of elevated water bacteria counts. All advisories finally lifted on July 31.
