On Oct. 9, 2025, deputies with the Humboldt County Sheriff’s Office Marijuana Enforcement Team served two search warrants to investigate illegal cannabis cultivation in the Island Mountain area. The California Department of Fish and Wildlife and the Bureau of Land Management assisted with the service of the warrants.
The parcels did not possess the required county permit and state license to cultivate cannabis commercially.
During the service of the warrants, assisting agencies discovered multiple water pollution violations, which carry fines of up to $20,000 per day, per violation. Deputies eradicated approximately 280 cannabis plants and seized more than 1,092 pounds of processed cannabis bud and shake. Deputies also located and confiscated 15 pounds of hash.
Additional violations with civil fines are expected to be filed by the assisting agencies. No arrests were made during the service of the warrant. The case will be forwarded to the DA’s Office for review.
Anyone with information about this case or related criminal activity is encouraged to call the Humboldt County Sheriff’s Office at (707) 445-7251 or the Sheriff’s Office Crime Tip line at (707) 268-2539.
