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. -

Mojave National Preserve California
A fact sheet from 2017 Dougall Photography/iStockphoto Mojave’s $131.8 million maintenance backlog includes repairs to historic buildings such as the Kelso Depot. Shane McMurphy/iStockphoto Mojave National Preserve California Overview Two hours from the hustle and bustle of Las Vegas and 100 miles from the nearest lodging lies California’s Mojave National Preserve. The Las Vegas Review-Journal dubbed this vast desert in San Bernardino County the “perfect escape for those seeking serenity.” The preserve spans 1.6 million acres, making it the third-largest National Park Service (NPS) unit in the contiguous United States. Mojave is ecologically and geologically diverse, with towering sand dunes, dun-colored mesas, and volcanic formations providing habitat for its abundant plants and wildlife. In addition to the densest forest of Joshua trees in the world, visitors can see bighorn sheep, bobcats, golden eagles, and breathtaking displays of seasonal wildflowers. The preserve also has a rich cultural heritage. Lands first inhabited by the Chemehuevi and Mojave tribes attracted gold miners in the late 19th century and were later crossed by several railroad lines. Visitors can learn more about this history through exhibits at the visitor center and by exploring archaeological sites, abandoned mines, and preserved homesteads and other buildings. The ghost town of Kelso, which once served as a Union Pacific Railroad depot and mining outpost, is one of the park’s most popular destinations. Unfortunately, Mojave faces over $131 million in deferred maintenance. Maintenance challenges Nearly all of Mojave’s needed repairs are for its road network. Severe deterioration of some sections of pavement has prompted the NPS to warn visitors of dangerous potholes. -

As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them. Appendixes I and II provide data on the number, acreage, and locations of wilderness study areas managed by BLM and the Forest Service, as well as data on the types of uses occurring in the areas. -

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. -
The California Desert CONSERVATION AREA PLAN 1980 As Amended
the California Desert CONSERVATION AREA PLAN 1980 as amended U.S. DEPARTMENT OF THE INTERIOR BUREAU OF LAND MANAGEMENT U.S. Department of the Interior Bureau of Land Management Desert District Riverside, California the California Desert CONSERVATION AREA PLAN 1980 as Amended IN REPLY REFER TO United States Department of the Interior BUREAU OF LAND MANAGEMENT STATE OFFICE Federal Office Building 2800 Cottage Way Sacramento, California 95825 Dear Reader: Thank you.You and many other interested citizens like you have made this California Desert Conservation Area Plan. It was conceived of your interests and concerns, born into law through your elected representatives, molded by your direct personal involvement, matured and refined through public conflict, interaction, and compromise, and completed as a result of your review, comment and advice. It is a good plan. You have reason to be proud. Perhaps, as individuals, we may say, “This is not exactly the plan I would like,” but together we can say, “This is a plan we can agree on, it is fair, and it is possible.” This is the most important part of all, because this Plan is only a beginning. A plan is a piece of paper-what counts is what happens on the ground. The California Desert Plan encompasses a tremendous area and many different resources and uses. The decisions in the Plan are major and important, but they are only general guides to site—specific actions. The job ahead of us now involves three tasks: —Site-specific plans, such as grazing allotment management plans or vehicle route designation; —On-the-ground actions, such as granting mineral leases, developing water sources for wildlife, building fences for livestock pastures or for protecting petroglyphs; and —Keeping people informed of and involved in putting the Plan to work on the ground, and in changing the Plan to meet future needs. -
