Pot plants in California may be profitable but they're sucking up the state's water sources during an ongoing drought. "If this activity continues on the trajectory it's on, we're looking at potentially streams going dry, streams that harbor endangered fish species like salmon, steelhead," said Scott Bauer of the California Department of Fish and Wildlife. The average marijuana plant needs about 6 gallons of water a day, according to a local report that cited research. Pot growers object to that number, saying that the actual water use of a pot plant is much less.
