History was made Saturday as the emergency spillway at mighty Oroville Dam — the nation’s tallest — was brought into action because of damage at the dam’s main spillway.

A gaping hole — some 250 feet long and 45 feet deep — appeared Tuesday in the lower part of the main spillway, a concrete channel that rests on dirt.
