ORIGINAL STORY:
Crews are searching for a man who jumped into the San Joaquin River after his son fell out of a boat while fishing Friday.
The man's 10-year-old daughter called for help around 11:30 a.m. The child told California Highway Patrol that her 1-year-old brother had fallen out of a boat while they fishing on the river and her father had dove into the water to help him.
The one-year-old boy was wearing a life vest, however, their father was not.
Dispatch worked with the child to pinpoint exactly where they were.
The Sheriff's Office Marine Enforcement Detail arrived to help, along with a CHP helicopter, Contra Costa County Sheriff Marine assets, The United States Coast Guard, The Rio Vista Fire Department and the River Delta Fire Department.
The Coast Guard rescue boat reached the area first and found the victim's boat drifting on the river. The two children on the boat were rescued and reunited with family members.
The one-year-old boy was found floating in the river. First responders immediately began treating the child, who did not have a pulse. He was taken to a Sacramento area hospital by the CHP helicopter. He initially did not have a pulse and was taken to the hospital where Hampton said his conditions improved as of Saturday.
Crews are still searching for the children's father, who has been described as a 41-year-old Asian man.
The Sacramento Sheriff says the river is flowing very fast due to heavy rainfall and runoff.
The sheriff's office thanked all of the agencies who helped in the rescue, including the Drowning Accident Rescue Team and the California Department of Fish and Wildlife.
