Aerial photos reveal massive damage at the Oroville Dam site in California as outflow is stopped to allow for cleanup. The true extent of the damage to the crumbling Oroville Dam spillway was revealed this week as authorities shut off the water flow and exposed the gaping hole left by the erosion. Authorities this week started the huge clean-up process, with tons of rubble needing to be removed from the bottom of the spillway in order to get the Hyatt hydro-electric power plant back in operation. Up to a million cubic yards of debris from the crumbling, concrete chute that takes water down from the top of the dam will need to be removed by barges and excavators over the next seven days.
