A health warning - stay away from the Kings River.
From Fresno County to Tulare County, don't go near the water.
63-thousand gallons of raw sewage spilled from the waste water treatment plant in Reedley.
The water is contaminated and the Kings River has been closed to the public.
The sewage spill happened around eight o'clock on Monday night.
Tuesday evening, the Tulare County Health Department put out a warning that people should stay away from the water.
But some people had spent the day in the water near the source of the spill.
At Reedley Beach, families and children played in the Kings River.
Junior Garcia spent the day swimming here.
"We come here a lot and they haven't told us nothing about us getting contaminated, about anything," Garcia said.
Kids were fishing in the water. No signs were up warning people people about the danger.
The source of the raw sewage contamination is the waste water treatment plant in Reedley - according to the Tulare County Health Department.
"Unfortunately this sewage found its way into the Kings River and is now en route to local recreational areas, community swimming holes, and we're asking people to stay away from the water as it is contaminated," said Allison Lambert with the Tulare County Health Department.
The treatment plant is right near Reedley Beach. And close to Breanne Moench's house.
"A couple times a year it will smell like sewage and you get the smell and the whiff and stuff," Moench said.
She says this isn't the first time this has happened.
"At Cricket Hollow Park we've had problems with the sewage going across the parking lot spilling over," Moench said.
And Cricket Hollow Park sits right on the river.
Signs are supposed to go up in the days to come warning people not to swim or play in the water, don't eat fish caught in the river, and don't use the water for irrigation.
Any contact with water in the Kings could make you sick.
And that's now what Junior Garcia is worried about. "We were just swimming and crossing the river and it just makes me feel sick," Garcia said."
Tulare County has tested water samples but the results won't be back until Thursday at the earliest.
No word yet on how long the water will be off limits.
Once it's declared safe you can then go back into the water.
