This undated graphic released by the California Department of Fish and Wildlife shows daily estimated total water use in residences, greenhouses and outdoor grows in the Salmon Creek Watershed, in Humboldt County, Calif. Some drought-stricken rivers and streams in Northern California’s coastal forests are being polluted and sucked dry by water-guzzling medical marijuana farms, wildlife officials say _ an issue that has spurred at least one county to try to outlaw personal grows.
