OCEANSIDE–An estimated 11,400-gallon sewage spill in Oceanside Monday morning has resulted in the posting of contamination warning signs at Calavera Lake in Carlsbad, the San Diego County Environmental Health Department reports.
The spill began after a broken water main opened a sinkhole in the 4700 block of Lake Boulevard at approximately 8:40 a.m. The sinkhole ruptured a sewer main, causing sewage to flow until a pump station was shut down about 9:15 a.m. The escaped sewage went into a storm drain that empties into a creek south of Evening Canyon Road and Lake Boulevard in Oceanside. The creek flows southwest for approximately 4,000 feet before emptying into Calavera Lake in the City of Carlsbad.
Warning signs are posted at public access points along the north and west portions of Calavera Lake and will remain in place until samples confirm that water is no longer impacted.
