Sacramento - Today, the Department of Transportation (Caltrans) participated in the Oroville Dam Emergency Exercise conducted by the Department of Water Resources (DWR). This exercise simulated a catastrophic failure of the Oroville Dam, which is the tallest dam in United States at 770 feet.

Caltrans, along with numerous local, state, and federal government agencies, collaborated with DWR in this exercise, which is required by the Federal Energy Regulatory Commission. The purpose of this exercise is to periodically test and familiarize participants with roles, responsibilities, plans, and procedures associated with DWR's “Emergency Action Plan” for all of its dams.

Caltrans held a functional exercise that lasted all morning at its Sacramento headquarters and its Northern California district offices.

The functional exercise assumed that the dam had collapsed affecting major roads and bridges due to flooding in Butte, Colusa, Glenn, Sacramento, Solano, Sutter, Yolo, and Yuba counties. Emergency operations centers were activated at county, regional, and state levels. Caltrans participated by activating its Department Operations Center (DOC) in Sacramento and its District Emergency Operations Center (EOC) in Marysville.

Participating in this exercise is part of Caltrans’ annual training and exercise program identified in the 5-year training and exercise plan submitted to the California Emergency Management Agency.
