Big Spring Creek Threatened by PCBs

Montana’s Big Spring Creek, which flows through Lewiston, has been polluted by an unlikely source: the Big Spring Trout Hatchery. Flowing out of the Snowy Mountains with more than 90 million gallons a day, Big Spring Creek is a favorite of locals and premiere destination for traveling anglers. According to Karen Ogden in the Great Falls Tribune, “Just below the hatchery, samples of brown trout showed PCBs at 46 times the safe consumption limit.”
