Pagosa Springs serves as the focal point of this 2019 survey, situated where the San Juan River flows through a landscape defined by complex water management and high-country grazing. The map illustrates a dense network of early irrigation infrastructure, such as the Highline Ditch, Chapson Ditch, and Park Ditch, which redirect snowmelt from the surrounding peaks to support ranching operations like the Eoff Ranch.
