An egret is seen near a partially flooded field on Staten Island at the Sacramento San Joaquin River Delta near Walnut Grove, California September 4, 2013. California water officials have proposed redesigning two water diversion tunnels planned for the Delta, away from several small towns along the Sacramento River that Delta residents said would be threatened under the existing plan, and would be placed beneath Staten Island, home to a variety of wildlife. Water from the tunnels would flow to urban areas in the Silicon Valley, Los Angeles and San Diego and farmers in the San Joaquin Valley. Picture taken September 4, 2013.
