July 5, 2016 -  All trails at the Los Vaqueros Watershed are now open after four golden eagles fledged from three nests. 

This is good news after last year when no golden eagles fledged.  

Golden eagles are commonly found 12-months a year within the nearly 20,000-acre watershed.

During the spring and early summer months, CCWD is required to close trails and other public areas near active nesting sites. 

Trail closures are changed depending on the nesting habits and success of the golden eagles.  We'll keep this page updated, so please check before heading out to Los Vaqueros.

Golden Eagle Nest Closing Facts

  • Nesting golden eagles are extremely sensitive to the presence of people. They will leave their nest if they see people nearby. (Their eyesight is much better than human eyesight!)
  • People must stay at least one-half mile from the eagles to ensure a successful nest. CCWD closes trails near active nests.
  • Eagles who are disturbed are likely to leave the nest. This could cause eggs or chicks to die.
  • Nesting usually occurs from mid February to late June.
  • The coastal range in the greater Bay Area has the largest golden eagle population in the world. Some golden eagles live at Los Vaqueros year-round, while others just pass through the area.
