Who owns Colorado's rainwater?

Environmentalists and others like to gather it in containers for use in drier times. But state law says it belongs to those who bought the rights to waterways.

Reporting from Denver — Every time it rains here, Kris Holstrom knowingly breaks the law.

Holstrom's violation is the fancifully painted 55-gallon buckets underneath the gutters of her farmhouse on a mesa 15 miles from the resort town of Telluride. The barrels catch rain and snowmelt, which Holstrom uses to irrigate the small vegetable garden she and her husband maintain.

But according to the state of Colorado, the rain that falls on Holstrom's property is not hers to keep. It should be allowed to fall to the ground and flow unimpeded into surrounding creeks and streams, the law states, to become the property of farmers, ranchers, developers and water agencies that have bought the rights to those waterways.

What Holstrom does is called rainwater harvesting. It's a practice that dates back to the dawn of civilization, and is increasingly in vogue among environmentalists and others who pursue sustainable lifestyles. They collect varying amounts of water, depending on the rainfall and the vessels they collect it in. The only risk involved is losing it to evaporation. Or running afoul of Western states' water laws.
