It was just minutes past midnight of Christmas Eve 1955 when the Gum Tree Levee on the Feather River in Sutter County collapsed, sending a 21-foot wall of water into Yuba City. In the darkness of the night, the town would go into complete chaos, with families fleeing from their homes to escape the deadly flood.

1955  A Coast Guard helicopter was the first rescue unit to reach a flood disaster scene in Yuba, California.  Its crew hoisted 138 persons to safety within 12 hours.  The first 58 were made possible because of the light from a small handheld searchlight from positions of peril among chimneys, television antennas, and trees.  In all, the Coast Guard assisted Federal, state, and local agencies in saving over 500 persons by helicopters and boats.
