Sewage-contaminated waters flowing from the Tijuana River have shut down the Imperial Beach shoreline, including Camp Surf.
The season's rainfall has been pushing contaminated runoff from the river to the Tijuana Estuary and is still flowing, according to the County of San Diego Department of Environmental Health.
Officials already closed off the northern part of Tijuana Slough National Wildlife Refuge shore, but on Wednesday, workers saw ocean currents pushing potentially contaminated water farther north to Imperial Beach.
They have posted warning signs, telling people not to go into the water until tests deem it safe. It's unclear when that may be.
