More than 100 people in California’s North Valley have received voluntary evacuation notices due to rising floodwaters, KFSN-TV, Fresno, reported.

Firefighters rescued a horse from one of the mobile home parks that’s in the affected area. Three other mobile home and RV parks in Newman and Crows Landing are also impacted by the rising San Joaquin River.

Stanislaus County Sheriff’s Deputies are concerned about the presence of raw sewage and a lack of drinking water and electricity. But most residents have chosen not to leave their homes. Instead, some with RVs have just moved to higher ground.

Nancy Fennie said, “Just watching everything seep through where I had land. It’s scary to see. We have a playground down there now under water, but the good news is we got everyone out safely. And everyone is sticking together.”

Officials from the local office of emergency services do not expect the situation to get much worse. They decided to close the shelter they had set up in nearby Patterson Wednesday evening after only a handful of people used it.
