About The River

The Colorado River Below Granby has a rich history that brings a sense of adventure and allure. This river isn’t just a water body; it’s a centuries-old testament to the thriving ecosystems and human civilizations that depended on it. Starting its journey in the Rocky Mountains, it meanders through a kaleidoscope of topographies, giving life to the arid western states.

Historically, this river has been central to the lives of various American Indian tribes. In more recent history, the river was developed for extensive agricultural and urban use. Key infrastructures, like the impressive Granby Dam, were established for water distribution and hydroelectric power.
