Jaroso and Mesita anchor a landscape defined by an intricate network of irrigation infrastructure along the southern edge of the San Luis Valley. This 2016 survey shows how water management dictates the settlement patterns of Costilla County, with the Eastdale Culebra Canal and Eastdale Canal Number 2 feeding the agricultural grid. To the east, the dramatic elevation of San Pedro Mesa rises above the valley floor, providing a sharp contrast to the level fields where Costilla Cr meanders toward the border. Local transit relies on a structured system of county roads, while specialized waterways like the Jaroso Ditch and Chalifa Ditch sustain the high-desert farming economy. Large-scale water storage is visible at Eastdale Reservoir Number 1 and its northern counterpart, Eastdale Reservoir Number 2, both of which serve as critical nodes in this arid region's complex hydraulic system near Garcia.
