  • Sites Reservoir Project Public Draft EIR/EIS
    12. Aquatic Biological Resources 12.1 Introduction This chapter describes the aquatic habitat and fish resources found within the Extended, Secondary, and Primary study areas. Descriptions and maps of these three study areas are provided in Chapter 1 Introduction. Fish species of management concern include special-status species and species that have substantial tribal, commercial or recreation value. The biology and life history of these species are described in Appendix 12A Aquatic Species Life Histories. Permits and authorizations for aquatic biological resources are presented in Chapter 4 Environmental Compliance and Permit Summary. The regulatory setting for aquatic biological resources is presented in Appendix 4A Environmental Compliance. The descriptions and evaluation of potential impacts in this chapter are presented using a broad, generalized approach for the Secondary and Extended study areas, whereas the Primary Study Area is presented in greater detail. Potential local and regional impacts from constructing, operating, and maintaining the alternatives are described and compared to applicable significance thresholds. Mitigation measures are provided for identified significant or potentially significant impacts, where appropriate. The descriptions of species and biological and hydrodynamic processes in this chapter frequently use the terms “Delta” and “San Francisco Estuary.” The Delta refers to the Sacramento-San Joaquin Delta, as legally defined in the Delta Protection Act. The San Francisco Estuary refers to the portion of the Sacramento-San Joaquin rivers watershed downstream of Chipps Island that is influenced by tidal action, and where fresh water and salt water mix. The estuary includes Suisun, San Pablo, and San Francisco bays. 12.2 Environmental Setting/Affected Environment This section, which is organized by study area, describes fish and aquatic resources that would be affected by the implementation of the alternatives considered in this EIR/EIS.

  • 4. Climate and Hydrology Many Aspects of the Physical Setting of Butte County Play a Role in the Hydrologic Cycle Within the County
    Butte County 4. Climate and Water Inventory and Analysis Hydrology 4. Climate and Hydrology Many aspects of the physical setting of Butte County play a role in the hydrologic cycle within the County. Topography within the County significantly impacts precipitation patterns. Temperature variations influence whether precipitation falls as rain or snow, which in turn impacts the timing of surface water runoff. Temperature and other factors also influence the evaporative demand of the atmosphere and corresponding irrigation requirements for crops. Both surface water and extracted groundwater are used to meet the water demands. System components impacting water resources in the County described in this section include climate, surface water hydrology, and groundwater hydrology. 4.1 Climate Butte County has a Mediterranean climate with cool, wet winters and hot, dry summers. Unlike many locations in California, rainfall and winter snowpack in the Sierra Nevada provide significant surface water flows and groundwater recharge as water drains through the County. Climate variation within the County occurs primarily due to changes in elevation. Precipitation is least on the valley floor and greatest in the Foothill Inventory Unit (IU) and Mountain IU areas as elevation increases. Conversely, temperatures are warmest on the valley floor and coolest in the mountains. Similarly, reference evapotranspiration (ETo), a measure of evaporative demand, is greatest on the valley floor and least in the mountains. This variability in climate is discussed in greater detail in the following sections. 4.1.1 Precipitation Average annual precipitation generally increases from west to east across Butte County, associated with increasing elevation. Moisture-laden weather patterns from the Pacific Ocean travel west to east across California and Butte County during the winter months.

    Yuba County Water Agency Narrows Hydroelectric Project FERC Project No. 1403 SECTION 3 EXISTING ENVIRONMENT In addition to this introductory information, this section is divided into two subsections. Section 3.1 provides a general description of the river basin in which the Project occurs. Section 3.2 provides existing, relevant and reasonably available information regarding the resources. 3.1 General Description of the River Basin 3.1.1 Existing Water Projects in the Yuba River Basin Sixteen existing water projects occur in the Yuba River Basin. Eight of the water projects are licensed or exempt from licensing by FERC. Together, these eight projects have a combined FERC-authorized capacity of 782.1 MW, of which the Narrows Hydroelectric Project has approximately 1.5 percent of the total capacity. The remaining eight non-FERC-licensed projects do not contain generating facilities. Each of these water projects is described briefly below. 3.1.1.1 Narrows Hydroelectric Project The existing Narrows Hydroelectric Project is described in detail in Section 2 of this PAD. 3.1.1.2 Upstream of the Narrows Hydroelectric Project 3.1.1.2.1 South Feather Power Project The 117.5-MW South Feather Power Project, FERC Project No. 2088, is a water supply/power project constructed in the late 1950s/early 1960s and is owned and operated by the South Feather Water and Power Agency (SFWPA). None of the project facilities or features is located in the Yuba River watershed except for the Slate Creek Diversion Dam, which is located on a tributary to the North Yuba River.

  • Foothill Yellow-Legged Frog Comments
    The Center for Biological Diversity submits the following information for the status review of the foothill yellow-legged frog (Rana boylii) (Docket #FWS-R8-ES-2015-0050), including substantial new information regarding the species' biology, population structure (including potential Distinct Population Segments of the species), historical and recent distribution and status, population trends, documented range contraction, habitat requirements, threats to the species and its habitat, disease, and the potential effects of climate change on the species and its habitat. The foothill yellow-legged frog has experienced extensive population declines throughout its range and a significant range contraction. Multiple threats continue unabated throughout much of the species’ remaining range, including impacts from dams, water development, water diversions, timber harvest, mining, marijuana cultivation, livestock grazing, roads and urbanization, recreation, climate change and UV-radiation, pollution, invasive species and disease. The species warrants listing as threatened under the Endangered Species Act.
