Imagine if you could follow a drop of water on a 900-mile journey downstream from mountains to plains. Imagine you could listen to its myriad stories as it makes its way from an alpine trout stream to a prairie river full of cranes or from a staircase of massive dams and reservoirs to a six-inch pipe that waters a farmer’s crop field. The Platte River Basin is one of the most appropriated river systems in the world. Every drop of water is spoken for, and little is free. The basin supports an industrial, agricultural powerhouse laid over one of the most endangered and altered grassland ecosystems on earth. Beneath the ground, it harbors more than half of the mighty Ogallala Aquifer; fossil water whose quantity and quality are at stake. In an age of climate change and economic uncertainty, this basin is being asked to be both food producer and energy pump. What if we could use the tremendous power of photography and storytelling to see a watershed in motion? What if we could leverage those images to dig deeper and grow understanding about our water resources, and build community throughout a watershed? What if this could be used as a template to start a conversation and look at other watersheds around the world?
