The U.S. Fish and Wildlife service believes the duck deaths reported at the pond at the SBSA treatment plant at 1400 Radio Road in Redwood Shores are linked to avian cholera deaths previously reported in Hayward, although the cause of death has not yet been confirmed, SBSA officials said Thursday.
The pond, technically a "landscape impoundment," was created in 1998 to eliminate dust from the area, which was harmful to the plant's equipment, according to SBSA officials. It is fed by a flow of recycled water from the treatment facility.
"Over the years this body of water has met the goal of eliminating dust from the dry, bare land next to the treatment plant and has become a popular spot for bird watchers," said SBSA Manager Dan Child.
The pond is noted for its large number of birds and easy access, even for those with disabilities, according to the Sequoia Audubon Society's web site.
Avian cholera does not harm humans but can kill waterfowl, gulls and other species, according to fish and wildlife officials.
Officials are asking the public to report any other dead birds in the area.
