Hydrogeologic investigation of the northern Taos Plateau, Taos County, New Mexico - Open-file Report 544

The Taos Plateau in northern Taos County is a high-elevation, basalt-capped plain that lies between the Rio Grande and the Tusas Mountains. The plateau overlaps the New Mexico-Colorado border and forms the west rim of the Rio Grande gorge. The hydrogeologic field investigation of the northern Taos Plateau, conducted between October 2007 and October 2009, is the first comprehensive assessment of groundwater conditions on the Taos Plateau and interactions between local aquifers and the Rio Grande. The investigative approach integrates new and existing geologic, geophysical, hydrologic, and geochemical data. This study has been undertaken in parallel with a major investigation of the springs in the Rio Grande gorge (Bauer et al., 2007). These studies advance understanding of the groundwater system in the northern Taos Plateau, and the interconnection of groundwater and surface water along the Rio Grande in northern Taos County.
