DENVER — Colorado officials have created a plan to capture and protect trillions of gallons of water that flow out of the Rocky Mountains each spring, according to a report by the Associated Press.

California, which is in the middle of a major drought, and other states have claim to two-thirds of the water that comes from Colorado.

The state promises to make sure downstream states get every gallon they’re entitled to receive, but not one drop more.

The AP reports the 358-page draft water plan will be submitted to Gov. John Hickenlooper Wednesday. It addresses water issues related to a growing population, the environment and Colorado’s recreational economy.

It was prepared by the Colorado Water Conservation Board staff which intends to work with the Governor’s office to complete a final version one year from now. Hickenlooper issued an order in May 2013 directing the Board to prepare a water plan for the state.
