Draft Environmental Assessment for Fallon and Stillwater Hunt Plans
Draft Environmental Assessment for Waterfowl, Other Migratory Birds, Upland Game, and Big Game Hunting at Stillwater National Wildlife Refuge and Fallon National Wildlife Refuge Date: March 2020 This Environmental Assessment (EA) is being prepared to evaluate the effects associated with this proposed action and complies with the National Environmental Policy Act (NEPA) in accordance with Council on Environmental Quality regulations (40 CFR 1500-1509) and Department of the Interior (43 CFR 46; 516 DM 8) and U.S. Fish and Wildlife Service (550 FW 3) regulations and policies. NEPA requires examination of the effects of proposed actions on the natural and human environment. Proposed Action: The U.S. Fish and Wildlife Service (Service) is proposing to open hunting opportunities for antelope (also called pronghorn) on Stillwater National Wildlife Refuge (NWR or Refuge), and to open Fallon National Wildlife Refuge (NWR or Refuge) to hunting waterfowl, other migratory birds, upland game, big game, and other species. In 2003, the Service signed a Record of Decision for the final Comprehensive Conservation Plan and Environmental Impact Statement (CCP-EIS) for the Stillwater NWR Complex. This draft EA is tiered from the 2002 CCP-EIS and focuses specifically on adding opportunities for antelope hunting at Stillwater NWR and opening the Fallon NWR to hunting as described in the Hunt Plan. This proposed action is often iterative and evolves over time during the process as the agency refines its proposal and learns more from the public, tribes, and other agencies. Therefore, the final proposed action may be different from the original. The final decision on the proposed action will be made at the conclusion of the public comment period for the EA and the Draft 2020-2021 Refuge-Specific Hunting and Sport Hunting Regulations. -

5.1 Historic Period Human Interaction with the Watershed
Upper Carson River Watershed Stream Corridor Assessment 5. Human Interaction With the Watershed 5.1 Historic Period Human Interaction With the Watershed The purpose of this section is to summarize human activities that have had some effect on the Carson River watershed in Alpine County, California. Regional prehistory and ethnography are summarized by Nevers (1976), Elston (1982), d’Azevedo (1986), and Lindstrom et al. (2000). Details of regional history can be found in Maule (1938), Jackson (1964), Dangberg (1972), Clark (1977), Murphy (1982), Marvin (1997), and other sources. A book published by the Centennial Book Committee (1987) contains an excellent selection of historic photographs. Particularly useful is a study on the historical geography of Alpine County by Howatt (1968). 5.1.1 Prehistoric Land Use Human habitation of the Upper Carson River Watershed extends thousands of years back into antiquity. Archaeological evidence suggests use of the area over at least the last 8,000 to 9,000 years. For most of that time, the land was home to small bands of Native Americans. Their number varied over time, depending on regional environmental conditions. For at least the last 2,000 years, the Washoe occupied the Upper Carson River Watershed. Ethnographic data provides clues as to past land use and land management practices (see extended discussions in Downs 1966; Blackburn and Anderson 1993; Lindstrom et al. 2000; Rucks 2002). A broad range of aboriginal harvesting and hunting practices, fishing, and camp tending would have affected the landscape and ecology of the study area. Shrubs such as service berry and willow were pruned to enhance growth. -

Buyalski l/, P. E., M. ASCE ABSTRACT The nature of the upstream river inflow to a reservoir of a typical diversion dam determines how the releases downstream are made. River inflow can be (1) intermittent or (2) continuous with a wide variation in magnitude. The application of local automatic control for the releases from a diversion dam that has intermittent river inflow is limited. For this case, it is better to install a remote monitoring system and make the releases by manual operation. The diversion dam that has a continuous river inflow can utilize onsite control algorithms for the local automatic regulation of the releases downstream. This paper discusses the typical diversion dam and the two basic operational concepts. The criterion for selecting a remote monitoring-manual operated system versus a local automatic controlled system is included. The general concept of the remote monitoring system and the design of a practical local automatic controller are then discussed and a summary is provided. -
Upper San Joaquin River Basin Storage Investigation Draft
Chapter 11 Geology and Soils This chapter describes the affected environment for geology and soils, as well as potential environmental consequences and associated mitigation measures, as they pertain to implementing the alternatives. This chapter presents information on the primary study area (area of project features, the Temperance Flat Reservoir Area, and Millerton Lake below RM 274). It also discusses the extended study area (San Joaquin River from Friant Dam to the Merced River, the San Joaquin River from the Merced River to the Delta, the Delta, and the CVP and SWP water service areas). Affected Environment This section describes the affected environment related to geology, geologic hazards, erosion and sedimentation, geomorphology, mineral resources, soils, and salts. Where appropriate, geology and soils characteristics are described in a regional context, including geologic provinces, physiographic regions, or other large-scale areas, with some area-specific geologic maps and descriptions of specific soil associations. Geology This section describes the geology of the primary and extended study areas. Primary Study Area A description of the surficial geologic units encountered in the primary study area is presented in Table 11-1. Geologic maps of the primary study area and the area of project features are presented in Figure 11-1 and Figure 11-2, respectively.
