Hint: "The faucet" is not the correct answer.
If you live in Denver, Boulder and many other cities on the front range, at least some of your water comes from the upper Colorado River Basin on the other side of the Continental Divide. As you'll recall from 6th grade or thereabouts, that water is supposed to flow to the Pacific Ocean.
But the front range has been pulling water out of the upper Colorado for decades - and now water providers are planning to take even more. The question is - how much can you take before the river starts to die?
Tapped Out: The Upper Colorado on the Brink is a short documentary designed to make people think about the effect our water use in cities has on rivers and economies many miles distant.
