Over a hundred volunteers gathered at Big Break Regional Shoreline to remove the invasive water hyacinth from the kayak launch area in Oakley, California on Sunday, January 11, 2015.  Pictured here is Noel Jesus of Antioch, taking a break from pulling the hyacinth ashore.  The invasive species floated into the launch area and clogged access after the high winds and tides of a storm on December 29, 2014.  Photo/Victoria Sheridan
