The Colorado River is the source of water for most of the southwest and southern California. All those states have to share the water from the river, and a complex set of agreements known as the Law of the River governs how much water they can take in a given year. Over at Grist, they're doing a large series on the health of America's rivers. For a piece on the Colorado River, we worked together on this infographic, in partnership with New Belgium Brewery, to see which states are closing in on their limits. With populations growing, the remaining water could disappear fast.
