  • Lanfair Valley Groundwater Basin Bulletin 118
    Hydrologic Region Colorado River California’s Groundwater Lanfair Valley Groundwater Basin Bulletin 118 Lanfair Valley Groundwater Basin • Groundwater Basin Number: 7-1 • County: San Bernardino • Surface Area: 157,000 acres (245 square miles) Basin Boundaries and Hydrology This basin underlies Lanfair Valley in eastern San Bernardino County. The valley slopes southeasterly with valley floor elevations ranging from 3,500 to 5,000 feet above sea level. The basin is bounded by impermeable rocks of the New York and Castle Mountains on the north, of the Piute Range on the east, of the Hackberry Mountain on the south, and of the Providence Mountains and Mid Hills on the west. Caruthers Creek flows intermittently southeastward during periods of heavy precipitation. Piute Spring discharges groundwater from Lanfair Valley to an adjacent valley and other smaller springs are found throughout the valley. Average annual precipitation ranges from 7 to 10 inches. Hydrogeologic Description Water Bearing Formations The primary water-bearing formations are Quaternary and Tertiary age unconsolidated deposits that include highly indurated sand, silt, clay and gravel. The maximum thickness of these deposits is not known; however, a boring log indicates a thickness of at least 550 feet locally. Wells in these deposits yield about 3 to 70 gpm (Friewald 1984). Restrictive Structures The Cedar Canyon fault crosses the northwest portion of the basin; however, it is unknown whether or not this fault is a barrier to groundwater. Recharge Areas The principal sources of recharge are likely percolation of runoff from surrounding mountains, percolation of precipitation to the valley floor, and subsurface inflow from adjacent basins.

  • 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.

  • Preliminary Geologic Map of the Little Piute Mountains, San Bernardino County, California
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY Preliminary Geologic Map of the Little Piute Mountains, San Bernardino County, California by Keith A. Howard1, Michael L. Dennis2, Karl E. Karlstrom3, and Geoffrey A. Phelps1 Open-File Report 95-598 1995 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American stratigraphic code. Any use of trade, product, or firm names is for descriptive purpose only and does not imply endorsement by the U.S. Government. 1 Menlo Park, California 94025 2 Northern Arizona University, Flagstaff, Arizona 86002 3 University of New Mexico, Albuquerque, New Mexico 87131 Mapped 1978-1993 by K. Howard, P. Stone, K. Karlstrom, G. Phelps, M. Dennis, and students from Northern Arizona University. GEOLOGIC SUMMARY Introduction The Little Piute Mountains in the eastern Mojave Desert expose a series of folds and thrust faults involving metamorphosed Paleozoic strata (Miller and others, 1982; Stone and others, 1983). Detailed mapping of these structures was undertaken to help elucidate regional Mesozoic structural evolution. Earlier geologic maps were prepared by Cooksley (1960a,b,c,d, generalized by Bishop, 1964) and Stone and others (1983). Deformed and metamorphosed Paleozoic and Triassic rocks form a stratal succession that was originally deposited in shallow seas on the North American craton. Based on lithologic sequence the units are correlated with unmetamorphosed equivalents 200 km to the northeast in the Grand Canyon, Arizona, and 35-50 km to the west in the Marble, Ship, and Providence Mountains, California (Stone and others, 1983).

  • Piute Valley Groundwater Basin Bulletin 118
    Hydrologic Region Colorado River California’s Groundwater Piute Valley Groundwater Basin Bulletin 118 Piute Valley Groundwater Basin • Groundwater Basin Number: 7-45 • County: San Bernardino • Surface Area: 176,000 acres (275 square miles) Basin Boundaries and Hydrology This basin underlies a portion of Piute Valley in eastern San Bernardino County. The Piute Valley, and its underlying groundwater basin, extends into southern Nevada (Jennings 1961; Bishop 1963), but this report considers only the portion that lies within California. The basin is bounded by the nonwater-bearing rocks of the Dead Mountains on the east, of the Piute Range and Homer Mountain on the northwest, of the Piute Mountains on the southwest, and of the Sacramento Mountains on the southeast (Bishop 1963). The valley is drained by Piute Wash to the southeastern part of the valley, where the drainage enters the Needles Valley and flows eastward to the Colorado River. Annual average precipitation ranges from about 4 to 8 inches. Hydrogeologic Information Water Bearing Formations Groundwater in the basin is found in younger and older alluvium. Older alluvium of Pleistocene age consists of fine to coarse sand interbedded with gravel, silt, and clay. Younger alluvium of Holocene age consists of poorly sorted gravel, sand, silt, and clay (DWR 1954). Valley fill extends to at least 1,044 feet in the central part of the basin and 920 feet in the southeastern part of the basin. Wells in the basin yield a maximum of 1,500 gpm. Restrictive Structures A fault in this basin may be a barrier to groundwater flow (DWR 1954).

  • Biological Goals and Objectives
    Appendix C Biological Goals and Objectives Draft DRECP and EIR/EIS APPENDIX C. BIOLOGICAL GOALS AND OBJECTIVES C BIOLOGICAL GOALS AND OBJECTIVES C.1 Process for Developing the Biological Goals and Objectives This section outlines the process for drafting the Biological Goals and Objectives (BGOs) and describes how they inform the conservation strategy for the Desert Renewable Energy Conservation Plan (DRECP or Plan). The conceptual model shown in Exhibit C-1 illustrates the structure of the BGOs used during the planning process. This conceptual model articulates how Plan-wide BGOs and other information (e.g., stressors) contribute to the development of Conservation and Management Actions (CMAs) associated with Covered Activities, which are monitored for effectiveness and adapted as necessary to meet the DRECP Step-Down Biological Objectives. Terms used in Exhibit C-1 are defined in Section C.1.1. Exhibit C-1 Conceptual Model for BGOs Development Appendix C C-1 August 2014 Draft DRECP and EIR/EIS APPENDIX C. BIOLOGICAL GOALS AND OBJECTIVES The BGOs follow the three-tiered approach based on the concepts of scale: landscape, natural community, and species. The following broad biological goals established in the DRECP Planning Agreement guided the development of the BGOs: Provide for the long-term conservation and management of Covered Species within the Plan Area. Preserve, restore, and enhance natural communities and ecosystems that support Covered Species within the Plan Area. The following provides the approach to developing the BGOs. Section C.2 provides the landscape, natural community, and Covered Species BGOs. Specific mapping information used to develop the BGOs is provided in Section C.3.
