said Peter Soeth, a spokesman for the bureau. He said the evaluation was begun "at the request of various water districts in the West."
Local water districts in Washington state and Colorado, where recreational marijuana is now legal, contract with federal water projects for supplies. Officials from some of those water districts said they assume the feds are going to turn off the spigots for marijuana growers.
“Certainly every indication we are hearing is that their policy will be that federal water supplies cannot be used to grow marijuana,” said Brian Werner at Northern Colorado Water Conservancy District, which handles approximately one-third of all water for northeastern Colorado and is the Bureau of Reclamation's second-largest user in the number of irrigated acres.
Washington state’s Roza Irrigation District, which supplies federal water to approximately 72,000 acres in Yakima and Benton counties, has already issued a “precautionary message” to water customers that may be involved in state-legal cannabis growing.
