Wyoming wants to modify the Fontenelle Dam so it can use an extra 80,000 acre-feet of water from a tributary of the once-mighty Colorado River. At its headwaters, Denver Water hopes to expand a reservoir’s capacity by 77,000 acre-feet of water. And several hundred miles south, Utah is trying to build a pipeline that can funnel another 86,000 acre-feet out of the river.

There are at least six high-profile projects in Utah, Colorado, and Wyoming that combined could divert more than 300,000 acre-feet of water from the beleaguered Colorado River. That’s the equivalent of Nevada’s entire allocation from the river.
