By mid-summer 2016, Sheriff Lopey concluded that fining the growers was useless.[1] Sheriff’s volunteers teamed up with the county prosecutor’s office and state Fish and Game officials to raid the fields.[1] Officers cleared as many as three fields a day, raiding 113 grows in four months.[1] Fifty Hmong growers were hauled off to jail.[1]

The teams seized generators and water pumps and destroyed 9,200 cannabis plants and 3,000 pounds of marijuana.[1] Lopey estimated the raids destroyed as much as 20% of the 2016 crop.[1] The summer operation produced fewer than two dozen criminal cases, which county judges dismissed after California voters made illegal cultivation a misdemeanor that November.[1]

Siskiyou County supervisors had banned outdoor cultivation in November 2015 after complaints about fences, water trucks, fertilizer runoff and trash.[1]
