As the most dammed, dibbed, and diverted river in the world struggles to support thirty million people and the peace-keeping agreement known as the Colorado River Pact reaches its limits, WATERSHED introduces hope. Can we meet the needs of a growing population in the face of rising temperatures and lower rainfall in an already arid land? Can we find harmony amongst the competing interests of cities, agriculture, industry, recreation, wildlife, and indigenous communities with rights to the water? Sweeping through seven U.S. and two Mexican states, the Colorado River is a lifeline to expanding populations and booming urban centers that demand water for drinking, sanitation and energy generation. And with 70% of the rivers’ water supporting agriculture, the river already runs dry before it reaches its natural end at the Gulf of California. Unless action is taken, the river will continue its retreat – a potentially catastrophic scenario for the millions who depend on it.

The highest mountain range in the world, the Himalayan range is far reaching, spanning thousands of miles, and holds within it an exceptionally diverse ecology. Coniferous and subtropical forests, wetlands, and montane grasslands are as much a part of this world as the inhospitable, frozen mountaintops that tower above. The word Himalaya is Sanskrit for abode of snow, fitting for a stretch of land that houses the world’s largest non polar ice masses. Extensive glacial networks feed Asia's major rivers including the Ganges, Indus, and Brahmaputra. More than a billion people rely on these glacier-fed water sources for drinking water and agriculture. The Himalayas are not only a remarkable expanse of natural beauty. They're also crucial for our survival.
