A Burned Area Emergency Response (BAER) Team
was ordered for the San Gabriel Complex. BAER is the rapid assessment of burned watersheds to identify imminent post-wildfire threats to human life and safety, property, and critical natural resources or cultural resources on affected lands. Fires result in loss of vegetation, exposure of soil to erosion risks, and increased water runoff that may lead to flooding, increased sediment, debris flows, or damage to critical natural and cultural resources.

Please take personal responsibility and prepare long before the threat of a wildland fire so your home is ready in case of a fire. Create defensible space by clearing brush away from your home. Use fire-resistant landscaping and harden your home with fire-safe construction measures. Assemble emergency supplies and belongings in a safe place. Plan escape routes and make sure all those residing within the home know the plan of action. Pack your emergency items. Stay aware of the latest news and information on the fire from local media, your local fire department and public safety. Follow your personal wildland fire action plan. Doing so will not only support your safety, but will allow firefighters to best maneuver resources to combat the fire.

The Reservoir and Fish Fires began on June 20th as separate incidents. The cause of the Reservoir Fire was due to a vehicle crash with a fatality while the cause of the Fish Fire is still under investigation. The fires were burning in fuel that was 7 – 10 years old with 6 to 8-foot chaparral and large grass crop. The Reservoir Fire grew that first day to 1200 acres. The Fish Fire grew to 3700 acres and threatened homes. Initial concerns ware that the two fires would merge into one fire. Fire crews established and provided for structure defense. No homes or structures have been damaged.

At the height of the fire, 1376 homes were evacuated. The American Red Cross established an Evacuation Center and 1460 staff from multiple local, state and federal agencies worked to protect property and suppress the fire. Road closures were in place and law enforcement patrolled for security while firefighters worked through the night to contain the fire. A town hall event was held in Duarte June 22 to answer questions and assure residents of the commitment of staff to this community.

There was a threat to the communities of Duarte, Bradbury, Azusa, Monrovia, Mountain Cove, Sunnnydale and Mt. Olive. Risks existed for the power grid in the San Gabriel Valley, nesting bald eagle habitat, Santa Ana Sucker Habitat, San Gabriel watershed and adjacent reservoirs that provide drinking water to Azusa and Duarte.

The Southern California Interagency Management Team 3 will transition the management of the fire to a Type III Incident Management Team tomorrow, June 30, 2016 at 6 a.m.



The Southern California Interagency Management Team 3 is grateful for the professionalism, cooperation and support they have received during the San Gabriel Complex from the Angeles National Forest, Los Angeles County Fire Department, and Los Angeles County Sheriffs Department, Azusa Police Department, assisting agencies, and local communities.
