On Tuesday, the California Department of Water Resources released water down the newly-rebuilt Oroville Dam spillway for the first time in over two years.

The spillway caused a crisis in February 2017 when a gaping hole opened in it during a storm, causing more than 180,000 residents to flee their homes over fears of flooding. Since then, the Department of Water Resources has spent at least $1.1 billion repairing the spillway.

An independent forensic report released in January 2018 stated that the spillway crisis "cannot reasonably be 'blamed' mainly on any one individual, group, or organization," but named the practices of the Department of Water Resources, as well as regulatory and industry standard practices, as causes.

Joel Ledesma, deputy director of the state water project at the California Department of Water Resources, joins Insight to discuss the reopening.
