A Three-Dimensional Hydrogeologic Model from the Pecos Slope to the Southern High Plains, Southeastern New Mexico - Open-file Report 614

The southeastern portion of New Mexico, specifically the Pecos Slope region of the Sacramento Mountains and the lower Pecos River valley, was selected for this initial study of 3-D mapping due to its wealth of geologic data, including thousands of well logs from oil and gas exploration. The major aquifers in this region are divided up as the Pecos Valley Alluvium, the Southern High Plains Aquifer System, and the Permian Aquifer System. The water resources in this area are in high demand and under intense active management: groundwater is relied upon to support large agricultural and dairy/cattle industries, as well as a booming oil and gas industry; surface water use is strictly limited by the terms of the Pecos River Compact, further highlighting the need for this project.
