There are other Sikh mayors across the US -- Ravi Bhalla was elected earlier this month as mayor in Hoboken, New Jersey.
However, Ms Didbal is the first Sikh woman to be elected mayor in the country, the report said. She was elected to Yuba City Council in 2014 and is currently vice mayor. She is the first in her family to graduate from college.
"Seeing someone that looks like you, that comes from the same faith as you, to be elected in a public office in this country is inspiring and exciting. And it's definitely moving," Jaydeep Singh with the Sikh Coalition said.
The Sutter-Yuba region is home to one of the largest Sikh communities in the US. On November 8, Mr Bhalla became the first Sikh mayor of New Jersey's Hoboken city after a stiff competition that turned ugly when he was labelled a terrorist in slanderous flyers.
The Sikh Coalition estimates some five lakh people who follow the Sikh faith live in the United States.
