But the county attorney cautioned that the move was unlikely to bring in significant revenue, because many inmates were destitute and because convicts would be expected to pay restitution and other fines first.

Like all counties in California, Riverside is in the midst of accepting a new influx of inmates who would have normally gone to state prison. Faced with an order from the Supreme Court to shed 30,000 prisoners from state prisons over the next two years, the Legislature approved a plan to shift thousands of prisoners to local jails.

Many local leaders and law enforcement officials are skeptical of the plan and say the state is unlikely to cover the counties’ costs for the new inmates. In many counties, including Riverside, the jails are already near capacity, and officials worry about being forced to release some inmates before their sentences are complete.

Under California law, counties are allowed to collect money as a condition of probation, but only after a judge determines that the inmate can afford to pay. And counties are the last in line to get money from a convict.

A similar plan has been floated in Kern County, north of Los Angeles. But the sheriff there, Donny Youngblood, has opposed the idea, saying it could cost more than it would bring in.

“I’m not against it, believe me. I think in a perfect world, if all of them could pay, I would be in favor of it,” Sheriff Youngblood said. “It’s not so much that I am concerned about the fairness, although there is an aspect of that. It’s simply not a road I think is worth going down right now.”

But, he added, “If it’s successful, there will certainly be others who follow, because we are all looking for more money.”

With five jails spread throughout the county, Riverside, which is east of Los Angeles, has already reached 93 percent of its capacity, up from 85 percent before the state began moving prisoners in October. Those inmates have much longer sentences — they will stay in county jail an average of two years, more than double the length of stay for typical county inmates.

“Overcrowding is one of my top concerns,” said Jerry Gutierrez, a chief deputy at the Riverside County Sheriff’s Department who oversees the jails. “You have an overcrowded facility, and it just builds up the tensions. It becomes a longer wait for the showers — not everybody is going to get in there. There’s less time outside of cells, and it demands more resources we may not have.”

The effects of the state’s transfer plans are not limited to the jails. For years, the state has relied on inmates convicted of nonviolent crimes to join crews that fight wildfires across the state. But because of the shift of so many prisoners to county jails, the firefighting force will begin to shrink this year. (Counties can send prisoners to the fire camps, but the state will charge those that do about $46 per prisoner per day, reducing the incentive.)

Mr. Stone, a Republican who has been so critical of the Democratic-controlled Legislature that he has called for the secession of the eastern part of the state, said the state’s plan amounted to a “partially unfunded” mandate. Riverside officials have said they were getting enough money from the state now, but they worry about next year, when the guarantee for a financing source expires and voters will be asked to approve tax increases to ensure that services do not erode.

“We need to be looking for revenue wherever we can for ourselves,” Mr. Stone said. “There are people who have the means and who get into trouble with the law. Why should the citizens of this county with other struggles be forced to pay for that? The Lindsay Lohans of the world can certainly pay for it themselves.”

Sharon Dolovich, a law professor at the University of California, Los Angeles, said the county faced a “tremendous blood-from-a-stone problem” and called the plan an “illogical, ill-thought-through response” to the state transfer of prisoners.

“If our goal as a society is to rehabilitate people who have been in jail, then burdening them with another thing to pay when they are released is not the way to do it,” Professor Dolovich said. “It could also create an incentive to deny bail just so that the county could be bringing in more money.”

For now, most neighboring counties are watching what happens with a skeptical eye.

“Sometimes you attack the absurd with the absurd,” said John M. W. Moorlach, an Orange County supervisor. “We’re all messaging to Sacramento that the state has do more than just take our money and download prisoners to us. We’re all finding different ways to scream.”
