The La Plata River valley in San Juan County defines this high-desert landscape near the New Mexico-Colorado border. This 2013 survey illustrates the complex irrigation network vital to the region, featuring named canals such as the Highland-Park Ditch, Greenhorn Ditch, and McDermott Ditch. These waterways support the small settlement of La Plata, where the local Po and nearby LaPlata Cem anchor the community history.
