The Dolores River carves through the northern landscape of this region, serving as a primary corridor for both natural drainage and human activity. The town of Dolores sits at the western edge, where the canyon opens up and meets the higher plateau. To the south and east, an intricate network of irrigation systems including Summit Ditch, Camp Ditch, and Main Ditch feeds several significant water bodies like Summit Reservoir and Puett Reservoir. These waterworks highlight the agricultural development of the Montezuma County highlands, transforming the dry mesas into productive land.
