From the Oregonian:
Police discovered at least 200,000 marijuana plants in raids during the busy Oregon growing and harvest season that just ended.
They also came upon jury-rigged irrigation pools filled with chemical fertilizers, causing worry among officials and environmentalists that already-threatened steelhead runs could be at risk.
In Grant County, for example, dams and chemical-laden pools were discovered along crystal-clear tributaries of the John Day River. Pot-growing operations, most run by Mexican cartels, pour fertilizer into the pools and run irrigation lines to their plants.
“They dump it by the 50-pound sack right into the water supply,” said Grant County Sheriff Glenn Palmer, whose department seized 60,000 pot plants at nine operations this summer in raids with the Oregon State Police, the U.S. Forest Service, the U.S. Bureau of Land Management and other agencies.
“It’s a really concentrated level,” he said. “You know it’s got to be harmful for the environment.”
Interestingly enough, Portland opened its first pot dispensary. The disconnect between marijuana laws, the added confusion of the DEA’s hands off policy and how to handle growers is starting to take its toll.
