Congressman urges FBI to take action on illegal marijuana grow‑ops in northern California

Rep. James Gallagher (R‑California) sent a letter to FBI Director Kash Patel on Monday urging the agency to intensify its crackdown on illegal marijuana cultivation in Siskiyou County and surrounding areas of northern California. In the missive, the congressman cited a recent report from the Siskiyou County Sheriff’s Office that highlighted the scale of the illicit operation, its impact on local ranchers and the environment, and a possible link to Chinese organized‑crime networks.

A growing threat to rural water supplies

Gallagher described the illegal operations as “entire rural properties now covered with rows of makeshift, plastic‑covered greenhouses, known as ‘hoop houses,’ where marijuana is cultivated using groundwater hauled in from nearby wells.” He warned that the cultivation has “depleted local water supplies” and “raised concerns about potential financing from Chinese organized‑crime networks,” adding that the practice “has harmed local ranchers, depleted groundwater supplies and raised concerns about potential financing from Chinese organized‑crime networks.”

The county’s 2025 enforcement report shows that local authorities eradicated 332,871 illegal marijuana plants and seized 54,070 pounds of processed cannabis. The county also cited an estimated 7,000 illegal growers in the Mount Shasta Vista subdivision alone. According to Gallagher, the illicit farms have spread onto federal lands, including the Shasta‑Trinity National Forest.

Ownership and financing questions

Gallagher pointed to ownership patterns that “raise serious concerns about who is actually financing and controlling these operations and whether the ownership arrangements are intended to conceal their involvement.” He cited a 2018 federal investigation in California that involved an illegal marijuana growing operation reportedly funded by money from China. That case led to forfeiture actions involving more than 100 properties in the Sacramento area.

In his letter, the congressman noted that “investigators have traced cultivation properties to individuals residing outside the county, while those managing the grows often have no apparent ownership interest.” He called for a deeper look at the financial and organizational structure of the illegal grow‑operations, suggesting that they could be part of a larger criminal network.

Environmental damage and pesticide use

The illegal grow‑sites are also a source of environmental contamination. Gallagher cited evidence that the growers use “highly toxic pesticides, including chemicals banned in the United States and products bearing Chinese‑language labels that are suspected of being illegally imported.” According to county findings, at least 27 pesticide compounds have been identified at illegal grow sites. The county has warned that these chemicals could pose risks to residents, law enforcement officers, and first responders.

“Compounding these concerns is the widespread use of highly toxic pesticides, including chemicals banned in the United States and products bearing Chinese‑language labels that are suspected of being illegally imported,” Gallagher wrote. He also highlighted the potential for contamination of local agricultural land, which could impact farmers and ranchers who rely on the same water sources.

The broader context

California’s marijuana legalization has led to a robust legal market, but the surge in demand has also fueled a thriving black‑market sector in some rural areas. Gallagher’s letter comes amid ongoing debates about the role of law enforcement in regulating cannabis cultivation, the protection of water rights, and the fight against transnational organized crime.

The FBI’s response to the letter has not yet been announced. Meanwhile, local officials in Siskiyou County continue to press the issue, citing the economic and environmental toll on the community. As the legal and illegal cannabis markets expand, the need for coordinated enforcement—both at the federal and local levels—remains a pressing concern for residents and lawmakers alike.
