Oroville Dam repairs now exceed $1 billion and ‘may be adjusted further’ as work continues

The price tag for the 2017 crisis at Oroville Dam has surged past $1 billion.

On Wednesday, the state Department of Water Resources revealed a $1.1 billion cost estimate for the massive repair work at America’s tallest dam. The cost of the emergency response, and the subsequent repairs to the dam’s two flood-control spillways, has periodically risen since officials made their initial estimates following the crisis, which triggered the evacuation of 188,000 residents.

DWR spokeswoman Erin Mellon, citing the enormity of the repair project, told reporters on a conference call that cost estimates “may be adjusted further” as work continues into 2019. DWR said it expects to have the dam’s two spillways substantially rebuilt by Nov. 1 and ready for the winter rains.
