Utah’s Supreme Court has upheld a ruling rejecting a proposal to pipe 55,000 acre-feet of Green River water from Utah to Colorado’s Front Range. The long-debated project, led by Fort Collins developer Aaron Million and Water Horse Resources, would have sent water more than 300 miles across Wyoming. The court agreed with the state engineer’s finding that Water Horse must prove the water would be beneficially used in Colorado before any export can be approved. Conservation groups are calling the decision a major victory for the Colorado River, while Million says the project isn’t over yet.
