REGIONAL: FEMA activates to support California with potential Oroville Dam auxiliary spillway failure
NORTHERN CALIFORNIA – The U.S. Department of Homeland Security’s Federal Emergency Management Agency, or FEMA, through its Regional Response Coordination Center in Oakland and its National Response Coordination Center in Washington, D.C., are monitoring impacts of the severe weather in California and the erosion to the Oroville Dam spillway and remains in close coordination with state and tribal officials in affected areas.
FEMA is coordinating support for the state of California in its preparation and response to the potential Auxiliary Spillway failure near Oroville in Butte County.
The FEMA Regional Response Coordination Center located in Oakland has activated in response to the emergency with a 24-hour operational tempo.
“We activated to ensure we’re postured to rapidly respond to any needs that California may have to protect life and property,” said Acting FEMA Administrator Dr. Ahsha Tribble. “We encourage residents in the affected to area to follow the direction of local authorities, and if told to stay out of evacuated areas, please do so.”
A FEMA Incident Management Assistance Team, or IMAT, is onsite at the California State Operations Center in Sacramento. The IMAT is an emergency response strike team comprised of specialists in the fields of operations, logistics, external affairs, finance and administration, and other key management positions.
According to the National Weather Service, an active weather pattern will return to Northern and Central California for the middle to latter portion of the week as a series of storm systems track across the region.
The National Weather Service forecasts the heaviest precipitation is expected Wednesday night into Thursday morning and again Friday into Friday night.
Additional rainfall may cause excessive runoff within the river basins and may pose additional stress on the Oroville Dam spillway situation.
The state requested and FEMA logistics will supply 150,000 one-liter bottles of water; 20,000 blankets; and 10,000 cots to the state today.
FEMA’s Liaison Officers continue to work with the California Office of Emergency Services Operations Center and the California Department of Water Resources State-Federal Flood Operations Center.
FEMA encourages those in the areas affected, or potentially affected by the severe weather to monitor local radio, TV stations or official social media accounts for updated emergency information, and to follow the instructions of state, tribal and local officials.
As of Monday evening, the California Department of Water Resources advised that the primary spillway continued to flow at 100,000 cubic feet per second and lake levels have dropped to 894 feet.
After evaluating the erosion on the emergency spillway, a plan was put in place to prevent further erosion. Utilizing trucks and helicopters, crews moved large rocks and gravel to fill erosion on the emergency spillway. Department of Water Resources staff continues to inspect and evaluate the emergency and primary spillways for further erosion.
Total discharges from the reservoir remain consistent with flood control releases at this time of year under these weather conditions. Department of Water Resources does not expect the discharge from the reservoir to exceed the capacity of any channel downstream.
