Introduction

The Oroville Dam Failure Response Plan (ODFRP) outlines

immediate response activities with a focus on evacuations,

mass care, research and rescue in the event of a total failure

of the Oroville Dam. Although total failure is highly unlikely,

the impetus for this Plan was Oroville Dam spillway erosion

occurring in early February 2017 that led to the evacuation of

nearly 200,000 individuals in cities below the dam. This

framework supports the Department of Water Resources

Oroville Dam Emergency Action Plan and does not replace

existing local plans. While the Plan contemplates total failure,

it may be scaled and adapted to a lesser dam event.

Background

In January of 2017, record rainfall in the Feather River watershed led Department of

Water Resources (DWR) officials to release water down the Lake Oroville flood

control spillway. In early February 2017, DWR increased releases through the flood

control spillway to offset higher inflows from rainfall. During this process, DWR

discovered a large amount of debris coming out of the concrete-lined spillway and

stopped all releases to inspect the damage.

Given the extensive nature of the damage to the concrete, DWR authorities opted to

reduce flows to the damaged spillway. The lake, swollen from heavy storms, rose

nearly 50 feet in five days and on February 11, 2017 overtopped its emergency

spillway for the first time. On February 12, 2017, flows down the emergency spillway

caused erosion to progress up the right side of the emergency spillway. DWR officials

feared the erosion would cause the collapse of a concrete slab holding water in the

reservoir. Consequently, local officials ordered the mandatory evacuation of people in

towns downstream. DWR increased the gated control spillway releases to draw down

the water level. Within hours, water ceased flowing over the emergency spillway. On

February 14, 2017, authorities lifted the mandatory evacuation order, but asked

residents to remain vigilant. Crews have been working around the clock to repair the

eroded areas below the emergency spillway.

Catastrophic Planning Process For Base Plan and Unified Coordination Group (UCG) Approval

Management Objectives- Prepare for changing conditions in a dynamic situation and be prepared to adjust plans. - Keep cost commensurate with values at risk. - Provide public with key information, maintain positive public relations.

Control Objectives- Provide for public and emergency responder safety. - Position appropriate resources to anticipate changing conditions. - Coordinate information between cooperating agencies. - Evacuate or rescue citizens as necessary. - Provide for evacuee short and long term needs.

Risk / Current Threat If severe weather causes high inflows for sustained durations, reservoir levels will rise and

encroach into the operating freeboard. As a result, gated control spillway releases would be

increased to prevent the use of the emergency spillway. Currently, the Hyatt Power Plant’s

capacity to outflow up to 13,000 cubic feet per second has been impaired. Efforts are underway

to bring that outflow capacity back online to assist with potential high, sustained inflow events at

Lake Oroville. Extremely high releases in the gated control spillway could continue the erosion of

the spillway chute, but should not lead to a failure of the dam or the flood control gate structure.

In the event that the emergency spillway must be used, erosion areas in the spillway channel

and at the base of the spillway have been armored with boulders, aggregate, and cement slurry

to minimize further erosion and weakening of the emergency/auxiliary spillway.

How to Use this Plan The Oroville Dam Failure Response Plan is a contingency plan developed to assist emergency

management through a pre or post catastrophic dam failure. The Plan outlines the Concept of

Operations (CONOPS) to achieve desired outcomes based on existing capabilities. It calls for

the formation of state, federal and private sector partnerships, assisting local/tribal government

in gaining access and the execution of strategies. But the Plan does not execute the response.

The successful implementation of this Plan requires decisive action on the part of emergency

managers, especially those in leadership positions.

Successful execution requires decisions and actions of leaders in the organization to:

• Deploy personnel through deployment orders and mission assignments, contracts, or

memorandums of agreement.

• Form personnel into organizations and task forces directed by the Operations Section of the

Unified Command Structure and/or Unified Coordination Group.

• Provide initial Resource Phasing of critical staff and equipment.

• Provide initial Pre-Scripted Mission Assignments to be validated, than executed.

• Develop an access strategy and a temporary supply chain. That supply chain is developed by

the deployment of staging area management teams, communications capabilities, contract

support and transportation resources. The result is a capability to move resources from

unaffected areas to affected, isolated areas.

• Conduct “Movement Coordination” to evacuate, source, broker, schedule and direct

transportation, commodities and shelter operations.

• Coordinate and direct the actions of subordinate organizations through plans, directives,

operations orders, movement schedules and mission assignments.
