An east Forsyth man faces drug charges after authorities discovered a suspected indoor marijuana growing operation at his home on Lake Lanier.

According to the Forsyth County Sheriff’s Office, more than 30 suspected marijuana plants were found Monday in the house on Canon Bay Drive, which is off Buford Dam Road.

The estimated street value of the confiscated 30 pounds of plants is about $50,000, said Col. Rick Doyle, director of operations for the sheriff’s office.

Robert Wesley Williams, 52, who lives at the home, was charged with manufacturing marijuana, according to sheriff’s reports.

Williams was released later Monday from the Forsyth County Detention Center after posting an $11,110 bond.

Also arrested at the home was a 58-year-old Roswell woman, according to reports.

She was charged with possession of less than an ounce of marijuana, a misdemeanor, and released from custody after posting a $1,155 bond.

According to Sheriff Duane Piper, the drug discovery began with a traffic stop of another man Sunday night on Ga. 400 in south Forsyth.

Piper said that during the stop, which occurred about 11 p.m. near Shiloh Road, Sheriff’s Sgt. Richard Thompson discovered some suspected marijuana.

Thompson also gleaned additional information from the driver that led drug investigators to secure a search warrant for the house Monday.

“We found, in the basement of the home, 32 marijuana plants between 5 feet and 7 feet high,” Piper said. “We also discovered an unknown amount of marijuana buds that were drying and multiple pieces of equipment, such as lights and a filtering system, that are used in an indoor grow house.”

Doyle said the operation likely had a small impact on the marijuana trade in the metro Atlanta area.

“Grow houses” aren’t a common find for local law enforcement, Doyle said, but in-home operations aren’t rare either.

“I think there’s a lot more of them around that people don’t know exist or haven’t been found yet,” he said. “Especially with the tightened up enforcement and the war on drugs and the proliferation of hydroponics, there’s a lot more people growing their own.”

Williams is scheduled to appear in Forsyth County Superior Court on Feb. 18.
