Bulletin-164 — Climate Change in New Mexico Over the Next 50 Years: Impacts on Water Resources

cover image

By: N.W. Dunbar, D.S. Gutzler, K.S. Pearthree, F.M. Phillips, P.W. Bauer, C.D. Allen, D. DuBois, M.D. Harvey, J.P. King, L.D. McFadden, B.M. Thomson, and A.C. Tillery, 2022

Earth is warming in response to increasing atmospheric carbon dioxide. Global climate models project an average temperature increase across New Mexico of 5° to 7° F over the next 50 years. Other primary impacts are decreased water supply (partly driven by thinner snowpacks and earlier spring melting), lower soil moisture levels, increased frequency and intensity of wildfires, and increased competition and demand for scarce water resources. Snowpack and associated runoff are projected to decline substantially over the next 50 years, generating diminished headwater streamflow. Flow in the state's major rivers is projected to decline by 16% to 28%, and the frequency of extreme precipitation events, coupled with fire-driven disruption of vegetation in watersheds, is projected to at least double river sediment. The impacts of climate change on New Mexico's water resources are overwhelmingly negative.

The bulletin, which is the scientific foundation upon which New Mexico's 50-Year Water Plan is based, represents a compilation, assessment and integration of existing peer-reviewed published research, technical reports and datasets relevant to the broad topic of changes to New Mexico climate over the next 50 years, and resultant impact on water resources. This project, also known as the "Leap Ahead" analysis, also identifies significant data and modeling gaps and uncertainties, and suggests research directions to strengthen our understanding of climate and water resource changes

Open-file Report-618 — Hydrogeology and water resources of the Salt Basin, New Mexico and Texas

cover image

By: Stacy Timmons and Laila Sturgis, [eds.], 2022

INTRODUCTION

The Salt Basin is a hydrologically closed, semiarid basin shared across the southern region of New Mexico and westernmost Texas (Figure TS-1). Water resources in the southwestern United States are limited, and they are becoming further strained due to increasing aridity and rising temperatures in the face of climate change. Even with significant changes to current water use and robust conservation, exploration of new or alternative water resources may be necessary as water shortages occur in the Southwest. Historically, in New Mexico water resource exploration efforts have occurred in basins with limited groundwater pumping or population. The Salt Basin has been one such region of exploratory interest for several decades.

The process of determining a firm water budget in this region has long eluded and challenged researchers and consultants. Data density in some areas is too sparse to draw reliable conclusions, especially with regard to the subsurface. One of the biggest obstacles to fully quantifying the water resources in the region is simply its remoteness and isolation, in addition to limited data availability and groundwater access.

PURPOSE AND SCOPE OF THIS PROJECT

Beginning in 2019, the New Mexico Bureau of Geology and Mineral Resources (NMBGMR) and the New Mexico Institute of Mining and Technology (NMT) initiated research to assess the water resources of the Salt Basin region of southern New Mexico and westernmost Texas. This project was funded by the U.S. Bureau of Reclamation and was conducted in coordination with two graduate students at NMT, the U.S. Geological Survey (USGS), the New Mexico Interstate Stream Commission (NMISC), and consultants with the NMISC. The current study was initiated as a result of NMISC considering potential groundwater export from the New Mexico portion of the basin to other regions of New Mexico, particularly during times of reduced surface water availability.

The purpose of this project was to assess the water resources and evaluate the sustainability of pumping 100,000 acre-ft/yr in the Salt Basin region. In particular, the project’s scope addressed the Salt Basin regional water availability by (1) identifying and attempting to address data gaps where there is currently little or no information about the groundwater system; (2) refining estimates of the regional water budget, including groundwater recharge, storage, evapotranspiration, and pumping; (3) building and updating the hydrogeologic framework and numerical hydrologic model; and (4) running specific pumping scenarios in the revised model. These efforts focus attention on the region’s capacity to sustain current groundwater withdrawals in the Salt Basin and implications for future development in New Mexico. Additional techniques applied in this study included electromagnetic geophysical measurements to better characterize the subsurface of the Salt Basin and to evaluate use of these methods in identifying saline or brackish aquifers.

In the first year of this study, the research team compiled previous data and reports to build the data release report NMBGMR Open File Report 608 (Kelley et al., 2020). Kelley et al. (2020) included an overview of the Salt Basin geology, a description of the geophysical and geochemical studies completed by others, a review of the previous estimates for recharge, and discussion of the existing hydrologic models of the region. From this data summary, in the second year of this study, data gaps were identified and efforts were taken to fill them. The research team collected 13 new water chemistry samples, inventoried 20 wells in New Mexico, conducted geophysical surveys, and applied new recharge estimations, along with estimating groundwater storage and water use. Two student master’s theses were completed on portions of this research. This report is the final summary and synthesis of the work completed.

Guidebook-72 — Socorro Region III

cover image

By: Daniel J. Koning, Kevin J. Hobbs, Fred M. Phillips, W. John Nelson, Steven M. Cather, Anne C. Jakle, and Brittney Van Der Werff, 2022

Beautifully exposed geologic features in the Socorro region exemplify important events in the geologic history of central New Mexico. The relative ease of access to these intriguing features from the town of Socorro justifies a third NMGS visit to this area. The 2022 Fall Field Conference will showcase new mapping, geochronology, and other geologic studies that have occurred in the Socorro region since the 1983 Fall Field Conference. The array of rocks seen here include Proterozoic crystalline rocks, a relatively complete Pennsylvanian-Permian section, Oligocene volcanic rocks, Santa Fe Group deposits from all phases of rifting, and a complete set of post–Santa Fe Group, Quaternary terraces. Fault-propagation and fault-bend folds associated with the Laramide orogeny, in addition to rift-related domino-block tilting and half-grabens, are also nicely exposed in the Socorro area. This volume includes detailed road logs of the Socorro area, including the Little San Pascual Mountains. Twenty-one peer-reviewed, technical papers and seven minipapers present recent research of this important region.

There are two versions of this guidebook available, the complete guidebook (426 pages), and a version with just the road logs that is spiral bound (146 pages).

Special Publication-15 — A History of the Geology Program at New Mexico State University: 1890 to 2015

cover image

By: Thomas H. Giordano, 2022

The history behind the Department of Geological Sciences at New Mexico State University goes back one hundred and thirty years and is complex. This history, as told in the pages of this monograph, documents the important details behind the founding of the NMSU geology program and its growth and evolution to 2015. The program's history is conveniently divided into three administrative phases. Phase I comprises the first 55 years, during which the program's activities were managed by one or two regular academic departments of the University. In the Earth Sciences phase, the geology program was administered as a division, along with one or two other divisions in the same department. In its third phase, the geology program became a regular academic department within the College of Arts and Sciences, its current status as the Department of Geological Sciences. Two obvious legacies of NMSU's geology program are the Department of Geological Sciences and the geophysics program in the Department of Physics. However, the program's legacy is also reflected in the students who have taken its courses and the program's research output through the efforts of its faculty, graduate students, and undergraduate students. Since the mid-1960s, the geology program has produced a vast amount of research that has led to a sophisticated understanding of the geology of southern New Mexico and adjacent areas. Finally, through a better understanding of the geology program's academic evolution, the program's alumni and current students, faculty, and staff will have a more profound appreciation of their academic experience at New Mexico State University

Guidebook-71 — Geology of the Mount Taylor area

cover image

By: Bonnie A. Frey, Shari A. Kelley, Kate E. Zeigler, Virginia T. McLemore, Fraser Goff, and Dana S. Ulmer-Scholle, 2021

The Mt. Taylor area is a crossroad where geologic history, human history, and societal impacts intersect. Situated on the eastern edge of the Colorado Plateau and flanking the transition zone to the Rio Grande rift, Mt. Taylor is a late Pliocene stratovolcano located on the Jemez Lineament, an enigmatic NE-trending alignment of late Cenozoic volcanic centers. Mt. Taylor lies along the southeast margin of the San Juan Basin bounded by the Zuni (south) and Nacimiento (east) uplifts. Mt. Taylor also has some of the richest uranium deposits in the United States.

The human history of the Mt. Taylor region is no less compelling. Indigenous communities lived here for thousands of years despite Spanish conquest and the establishment of land grants. In the 1800s, the area was settled as part of a U.S. territory, bringing with it commerce such as the railroad and timber industries, and later the uranium boom and its lasting legacy. Additional corridors of commerce opened with Route 66, succeeded by Interstate 40. The designation of Mt. Taylor as a Traditional Cultural Property recognizes the mountain's importance to Native, Spanish and U.S. cultures.

The papers in this volume cover a spectrum of topics, ranging from geologic studies and mining history to the effects of mining on the population and the environment today.

There are two versions of this guidebook available, the complete guidebook (310 pages), and a version with just the road logs that is spiral bound (94 pages).

Open-file Report-616 — Evaluation of water-level trends using spatiotemporal kriging in the Mimbres Basin, southwest New Mexico

cover image

By: Geoffrey Rawling, 2021

Water-level measurements in the Mimbres Basin made in early 2020 were combined with data extending back to 1980 to characterize water level trends in the region. The geostatistical method of spatiotemporal kriging was used to create water-level maps every five years from 1980 until 2020. Changes in water-levels over these five-year intervals were calculated. Compared to traditional spatial kriging, the spatiotemporal approach offers improved precision, more realistic maps of water levels and water-level changes, fewer artifacts due to changing well networks over time, and overall less uncertainty in predictions.

Several notable patterns since 1980 are revealed in the sequential maps. From Deming to Columbus, water levels have declined up to 75 feet. Water-level declines and expansion of cones of depression appear to have slowed south of Deming and increased around Columbus in the past ten years. Water levels west of Red Mountain, east of the Florida Mountains, and northeast of Columbus have risen as much as 32 feet, presumably as a result of decline in pumping for irrigation in these areas that has resulted in flattening of cones of depression. The vicinity of Whitewater and Faywood shows net water-level rises over the 40 year period, but declines have occurred in the past ten years. Water levels have varied considerably along the reach of the Mimbres River south of Faywood, where most of the river’s flow infiltrates.

The spatiotemporal kriging approach is more challenging than other interpolation methods traditionally used in hydrogeology. However, the cost in funds and staff-hours of field studies to gather water-level data has always been high and continues to rise. Therefore it is prudent to analyze the data collected at such great expense with methods that will extract the most useful information. The present work builds on other recent studies and demonstrates that spatiotemporal kriging of water-level data is superior to spatial kriging in this regard.

Note:
This report was revised in February 2022 to correct minor typographical errors and to add location maps on figures 15 and 21. Appendices 1-3 are unchanged, but are now included with the body of the report. The interpretations of this work remain the same.

The Rio Grande: A River Guide to the Geology and Landscapes of Northern New Mexico

cover image

By: Paul W. Bauer, 2011

The Rio Grande is the fourth longest river in North America. Flowing nearly 2,000 miles from Colorado to the Gulf of Mexico, in New Mexico it occupies the Rio Grande Valley, where it provides water for habitat, agriculture, and a growing population. In northern New Mexico, where the river has carved a pair of spectacular canyons, the Rio Grande also provides some of the most exceptional recreation opportunities and scenery in North America. This comprehensive, spiral bound, river-friendly, 122-page river guide provides detailed, full-color maps of 153 miles of the Rio Grande, from Lasauses, Colorado to Cochiti Dam in New Mexico. Divided into eleven river stretches—including the popular whitewater runs in the Taos Box, Racecourse, and White Rock Canyon—the guide covers stretches that range in difficulty from placid canoe tours to gripping kayak descents. The river maps are developed on an aerial photographic base (digital orthophoto quads), allowing the user to more easily identify locations.

Minor updates were made to text and figures for reprinting in 2022.
