It began as a 200 foot wide, 30 foot deep crater in the Oroville Dam’s main spillway on Feb. 7, 2017.

One year ago today, 180,000 people living downstream along the Feather River were worried they'd lose their home and livelihood to flooding when the main and emergency spillways of the Oroville Dam were significantly damaged.

Last year, Northern California was slammed by record rainfall, which caused flooding in the Sacramento region.

On Feb. 12, 2017, the Butte County Sheriff's Department, under advice from the Department of Water Resource, called for the mandatory evacuation of 188,000 people.

An emergency group of construction crews swooped in with trucks and helicopters to make immediate repairs. Many stayed for months.

It has since become a nearly $900 million project and another $1 billion in potential lawsuits from the City of Oroville, farmers, and other residents.

A January 2018 independent report found that DWR officials made a series of bad decisions as early as the day the dam first stood such as ignoring technical advice, which led to the near catastrophe.
