A portion of the waters in Huntington Harbour, in the vicinity of the Sunset Aquatic and Portofino Cove marinas, has been closed because of a sewage spill.

The spill of about 2,000 gallons was caused by a private sewer clean-out blockage in Cypress, according to a news release from the Environmental Health division of the Orange County Health Care Agency on Sunday, April 1.

The area will stay closed to ocean water-contact sports until the results of follow-up water quality monitoring meet acceptable standards, the release said.
