Whiskey is for drinking, water is for fighting is a well-worn saying when it comes to water politics, but in the Colorado River Basin, where the most dammed, dibbed, and diverted river in the world struggles to flow, some think fighting may be the only way left to reclaim this valuable resource. Robert Redford’s voice hones the narrative of the threats to the once-mighty Colorado River, but Watershed is not all doom and gloom. It renders light moments that illuminate how letting go of the ways of old can lead to a convincing new water ethic – where, again, there can be enough for all.
