Prosecutors chose to charge the three accused.
Sheriff Schmidt said the three guards who had been charged had been suspended. A separate disciplinary process is expected to conclude on Friday.
The inquest jury that weighed evidence in the case a year ago had recommended prosecuting four other jail staffers, but Chisolm said he did not expect them to be charged.
Prosecutors allege Meadors gave the order to shut off water in 38-year-old Terrill Thomas's solitary confinement cell in April 2016 and that Ramsey-Guy was the jail staffer who physically closed the pipes, according to the Journal Sentinel.
Jail Cmdr. Nancy Lee Evans is charged with felony misconduct and misdemeanor obstructing an office. If convicted, each face more than three years in prison and $10,000 in fines.
In March 2017, Evans denied, at least 15 times, to district attorney investigators that Gold had watched the video and changed her story a couple of weeks later, the complaint stated.
The document Ms Evans signed off on answered that "there is no documentation indicating this". However, prosecutors say Evans was aware of the tape and that it showed the water to Thomas' cell being turned off and never turned back on again.
Thomas was arrested on April 14, 2016, after being charged with reckless endangerment and felony firearms violations after allegedly shooting a man in front of his parents' home and firing a weapon inside a casino.
The case was not the only time an inmate was punished by being deprived of water. Evans, the former commander of the Milwaukee County Jail, and two other jail staffers were charged Monday in connection with the dehydration death of Terrill Thomas.More news: U.S. to boost aid to Jordan, despite Trump's threats

All charges related to Thomas' arrest were dismissed following his passing. During the same year as Thomas' dehydration death, a baby died inside the facilities due to staff refusing to assist a detainee who was in labor. Clarke was not the target of the inquest into Thomas' death because he wasn't directly involved in Thomas' death.
Lieutenant Kashka Meadors ordered that Thomas' water access be turned off until he behaved, which violated a Milwaukee County Sheriff's regulation that inmates have continuous access to water.
All three were on administrative duty previously and did not have with inmates, Schmidt said.
According to Schmidt, anywhere from 20-25 percent of the county's inmates are on psychotropic drugs for mental health problems, and about as many have other significant health issues.
He also offered sympathy to the family of Thomas. Saying I'm sorry - is that good enough?
"Defendant Evans' course of conduct during the investigation into Mr. Thomas' death, of withholding information from her superiors, lying to her supervisors, failing to preserve evidence, repeatedly lying to law enforcement investigators and lying at the inquest, constituted misconduct in public office."
"It hurts me as a human being when I see someone suffer, when I see the families of anyone suffer", Schmidt said.
The Milwaukee County Jail has a history of failing to fix "appalling" conditions in accordance with an agreement among the county, the American Civil Liberties Union of Wisconsin Foundation and the Legal Aid Society of Milwaukee.
