Situation   Action
  • May 13, 2007: Two injured humpback whales, a mother and her female calf, are spotted in the Sacramento River near Rio Vista, CA
  • The endangered whales are swimming up river toward Sacramento and away from the Pacific
  • U.S. Coast Guard (USCG), the Marine Mammal Center and the National Oceanic & Atmospheric Administration (NOAA) determine a course of action
 
  • USCG Sector 11 out of San Francisco sends USCG Cutter PIKE with Lt. Gov. Garamendi onboard to lure the whales back with sound from a hydrophone
  • USCG, U.S. Fish & Wildlife Service, NOAA Fisheries, Contra Costa Sheriff’s Office vessels & California Highway Patrol (CHP) aircraft implement a safety zone around the whales for over two weeks
  • Scientists monitor and assess the whales’ health and behavior throughout each passing day…
Result  
  • May 31, 2007: The whales disappear past the Golden Gate Bridge back into the Pacific Ocean…
  • Officials do not know why they would swim upriver
