Lake Granby dominates the eastern landscape of this Grand County region, where the Colorado River meets the expansive waters of Arapaho Bay and Rainbow Bay. The map documents a complex water management system essential to the area, featuring the Willow Creek Pump Canal, Bunte Highline Ditch, and the Redtop Valley Ditch. These engineered waterways connect the Willow Creek Reservoir and smaller impoundments like Bunte Reservoir to the larger basin.
