Use of Radiocarbon Ages to Narrow Groundwater Recharge Estimates in the Southeastern Mojave Desert, USA
hydrology Article Use of Radiocarbon Ages to Narrow Groundwater Recharge Estimates in the Southeastern Mojave Desert, USA Adam H. Love 1,* and Andy Zdon 2 1 Roux Associates, Inc., 555 12th Street, Suite 250, Oakland, CA 95607, USA 2 Partner Engineering and Science, Inc., 1761 E. Garry Avenue, Santa Ana, CA 92705, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-415-697-6200 Received: 2 August 2018; Accepted: 10 September 2018; Published: 13 September 2018 Abstract: Estimating groundwater recharge in arid or semiarid regions can be a difficult and complex task, since it is dependent on a highly variable set of spatial and temporal hydrologic parameters and processes that are dependent on the local climate, the land surface properties, and subsurface characteristics. As a result, traditional methods for estimating the recharge can result in a wide range of derived values. This is evident in the southeastern Mojave Desert, where calculated recharge estimates by previous investigators that range over an order of magnitude (from ~2500 to ~37,000 acre feet per year) are reported. To narrow down this large span of recharge estimates to narrower and more plausible values, this study evaluates the previous recharge estimates in this region, to examine the sources of variability in the reported results and to constrain the recharge estimates based on the hydrologic conditions and the radiocarbon age-dating of spring flows—even without knowledge of the precise subsurface hydrology. The groundwater age and perennial flow characteristics of springs in this study could not be derived from waters sourced solely from local recharge. -

DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP MF-1603-A UNITED STATES GEOLOGICAL SURVEY MINERAL RESOURCE POTENTIAL OF THE COXCOMB MOUNTAINS WILDERNESS STUDY AREA (CDCA-328), SAN BERNARDINO AND RIVERSIDE COUNTIES, CALIFORNIA SUMMARY REPORT By J. P. Calzia, J. E. Kilburn, R. W. Simpson, Jr., and C. M. Alien U.S. Geological Survey and A. M. Leszcykowski and J. D. Causey U.S. Bureau of Mines STUDIES RELATED TO WILDERNESS Bureau of Land Management Wilderness Study Areas The Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976) requires the U.S. Geological Survey and the U.S. Bureau of Mines to conduct mineral surveys on certain areas to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a mineral survey of the Coxcomb Mountains Wilderness Study Area (CDCA-328), California Desert Conservation Area, Riverside and San Bernardino Counties, California. SUMMARY Geologic, geochemical, geophysical, and mineral surveys within the Coxcomb Mountains Wilderness Study Area in south eastern California define several areas with low to moderate potential for base and precious metals. Inferred subeconomic re sources of gold at the Moser mine (area Ha) are estimated at 150,000 tons averaging 1.7 ppm Au. The remainder of the study area has low potential for other mineral and energy resources including radioactive minerals and geothermal resources. Oil, gas, and coal resources are not present within the wilderness study area. INTRODUCTION Hope (1966), Greene (1968), and Calzia (1982) indicate that the wilderness study area is underlain by metaigneous and The Coxcomb Mountains Wilderness Study Area metasedimentary rocks of Jurassic and (or) older age intruded (CDCA-328) is located in the Mojave Desert of southeastern by granitic rocks of Late Jurassic to Late Cretaceous age. -

Mojave National Preserve Management Plan for Developed
Mojave National Preserve—Management Plan for Developed Water Resources CHAPTER 3: AFFECTED ENVIRONMENT Introduction This chapter describes the unique factors that influence water resource management in the Preserve and the resources that could be affected by the implementation of any of the alternatives described in Chapter 2: Alternatives. The resource descriptions provided in this chapter serve as a baseline to compare the potential effects of the management actions proposed in the alternatives. The following resource topics are described in this chapter: • Environmental Setting • Cultural Resources • Water Resources • Wilderness Character • Wildlife Environmental setting and water resources are important for context and are foundational for water resource management, but are not resources that are analyzed for effects. Resource issues that were considered and dismissed from further analysis are listed in Chapter 1: Purpose of and Need for Action and are not discussed further in this EA. A description of the effects of the proposed alternatives on wildlife, cultural resources, and wilderness character is presented in Chapter 4: Environmental Consequences. Environmental Setting The Preserve includes an ecologically diverse yet fragile desert ecosystem consisting of vegetative attributes that are unique to the Mojave Desert, as well as components of the Great Basin and Sonoran Deserts. Topography The topography of the Preserve is characteristic of the mountain and basin physiographic pattern, with tall mountain ranges separated by corresponding valleys filled with alluvial sediments. Primary mountain ranges in the Preserve, from west to east, include the Granite, Kelso, Providence, Clark, New York, and Piute Mountains. Major alluvial valleys include Soda Lake (dry lake bed), Shadow Valley, Ivanpah Valley, Lanfair Valley, and Fenner Valley. -
