The Río Marañón is free flowing from its headwaters in the Cordillera Huayhaush to the confluence with the Río Ucayali where the Río Amazona proper begins. This makes the Río Marañón a very special place. This is of course important for sediment and nutrient transport to the Amazon, natural flow regimes, and the local ecology. But above all, it is important for the people who live alongside the river. “The Pimary Source” is a documentary film of an extraordinary adventure at risk of being lost. The 39 minute film aims to give the people of the Marañón Valley a voice in the face of more than a dozen hydroelectric dams and highlight the spirit of adventure while navigating one of the most unique and beautiful rivers on Earth.
Thanks for watching!
