The birth of Oroville Dam | Watch construction of tallest dam in the U.S. in the 1960s

A 1990s documentary uses archival footage to detail the construction of the Oroville Dam, an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the United States that was built during the period 1961 to 1968. At 770 feet, it is the tallest dam in the United States and serves mainly for water supply, hydroelectricity generation and flood control. The dam's main and emergency spillways were significantly damaged in February 2017. This prompted the evacuation of more than 180,000 people living downstream along the Feather River.

See the damage evolve: Oroville spillway erosion over time

As seen from the air and ground level, the gaping hole in the spillway was first photographed by The Bee on Feb. 8, the same day that inspectors were sent via tether down into the hole. Water was released later that same day. Since then, we have documented the erosion caused by the force of water.
