In the earlier years it appears that Locke was able to keep gambling dens full of patrons without issue from the law, but it seems that it may have eventually caught up with them as time went on.

Still, when those raids did take place, they sure made headlines.
"Lockeport Raid Nets Seven Drug Victims"-
Completely surrounding a house in Lockeport in which it was believed the use of drugs was being indulged in early Sunday morning, netted Deputy Sheriffs W.R. Cook, H.D. Bryant, John Pendergast, George Wittenbrock and George Altucker, aided by Bob Cole, seven prisoners, five of whom were Chinese.
One white girl, Miss Frances Reese, aged 22, and Charles Mehner, white, also aged 23, were among those caught in the net thrown around the building. All were brought to the county jail in this city to be charged with using drugs. A part of the evidence obtained was the finding of a package of more than 1000 morphine tablets on one of the Chinese. He will be charged with running an opium den and violating the state poison act."--- Sac Union, 6/24/1919


It didn't stop there. Raids on opium dens and gambling houses were just getting started and would continue, as the public officials and law enforcement decided to crack down on Locke.
On March 8, 1920, Sheriff's deputies Brant and Cook raided an opium den in Locke (Lockeport). As the article in the Sacramento Union states, the raid was one of many in a "long campaign against drug users." Along with seizing pipes and "hop", two of the patrons using the drugs were arrested and brought to jail.
November 5, 1922, newspapers report of a "Sensational Raid upon Chinese den- Sheriff's deputies gain entrance to Lakeport [sic] house and arrest three.
Battering down the wooden doors of an alleged Chinese gambling den at Lockeport, while two deputies with drawn revolvers held a crowd of 30 gamblers at bay, deputy sheriffs from the office of Sheriff Jones raided the establishment of Tin Fan, in the river town last night.
Three Chinese were arrested and $1,500 taken from five tables. Those arrested were Tin Fan, housekeeper; Ching Sing, gamekeeper, and Gee Johnnie, gamekeeper. They were released on $900 cash bail. The arresting officers were H.D. Bryant, chief criminal deputy sheriff; H.C. Cann, criminal deputy sheriff, and Deputies Oagle and Slater.

Tin Fan, the proprietor of the house, suspicious and wary of the strangers, delegated several Chinese to watch them. After remaining in the place for 20 minutes, the deputies drew their revolvers and gave a pre-arranged signal. The officers on the outside broke down the door and lined the patrons of the place up against the wall."-- Sac Union, 11/5/1922
