Much of Newport Beach’s Back Bay is closed to swimmers after two sewage spills dumped a total of 15,000 gallons into the water Tuesday, according to the Orange County Health Care Agency.
The spills affected waterways between the northern tip of Back Bay and North Star Beach.
The first spill of about 7,500 gallons resulted from a sewer main break in Costa Mesa. The second spill of about the same size was caused by a private sewer lateral blockage in Santa Ana.
The water will remain closed to marine sports until follow-up water quality tests meet state standards, the Health Care Agency said.
A staff member at the Newport Aquatic Center at the southern end of the spill area said the center was operating normally Tuesday afternoon. The facility offers kayak and stand-up paddleboard rentals as well as rowing, canoeing and kayaking programs. The staff member said lifeguards put up signs at neighboring North Star Beach cautioning people not to go in the water.
