Carter Lake Reservoir dominates the rugged foothills west of Loveland, where the complex water management systems of the Front Range are on full display. This landscape is defined by its extensive network of irrigation and power infrastructure, including the Flatiron Penstocks descending from Flatiron Mtn and a series of smaller catchments like Lon Hagler Reservoir and Hertha Reservoir. The St Vrain Canal and Culver Ditch illustrate the intricate engineering required to move water through these dry valleys.
