The river rose another four inches overnight, and has flooded some yards. Officials have urged about 125 residents to evacuate, in four mobile home parks near the town of Newman.
All the parks are in low-lying areas prone to flooding, but some residents says they're staying put, including one man who moved to the area in 2008 after surviving a flood in Cedar Rapids, Iowa.
"I got a little money from FEMA. I moved out here where I thought the weather would be better. And here we are again," resident Karl Roush said.
Stanislaus County and the American Red Cross have opened a shelter for evacuees.
