draft Environmental Assessment (EA) is being prepared to evaluate the effects associated with the 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. Appendix 1 outlines all laws and executive orders evaluated through this EA. Proposed Action The U.S. Fish and Wildlife Service (Service) is proposing to maintain the current hunting and fishing programs with modifications to include opening refuge-specific seasons for the harvest of new game species including Eurasian collared-dove (Streptopelia decaocto), African collared- dove (Streptopelia roseogrisea), black-tailed jackrabbit (Lepus californicus), bobcat (Lynx rufus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), and kit fox (Vulpes macrotis). The Service is also proposing to add the incidental take of feral swine (Sus scrofa) by individuals participating in established hunting opportunities on the Havasu National Wildlife Refuge (Havasu NWR or refuge) in accordance with the refuge’s 2021 Hunting and Fishing Plan. The new 2021 Hunting and Fishing Plan replaces the refuge’s previous plan and proposes to expand upland game hunting to 33,148 total acres. This includes expanded hunting opportunities in the Topock Marsh West Management Unit. The 2021 Hunting and Fishing Plan expands a waterfowl sanctuary to 25,962 acres; permits waterfowl hunting on 11,869 acres; and requires federally approved nontoxic shot for all hunted species, with the exception of desert bighorn sheep (Ovis canadensis nelsoni). The 2021 Hunting and Fishing Plan adds additional hunting days for mourning dove (Zenaida macroura) and white-winged dove (Zenaida asiatica), and creates an expanded, refuge-specific season for desert cottontail rabbit (Sylvilagus audubonii), Eurasian collared-dove, African collared-dove, black-tailed jackrabbit, bobcat, coyote, gray fox, and kit fox. The refuge seeks to more closely align the hunting program with State regulations and to provide additional hunting opportunities. A proposed action may

  • Havasu NWR Draft Hunting CD
    COMPATIBILITY DETERMINATION USE: Hunting (Migratory Birds, Upland and Big Game) REFUGE NAME: Havasu National Wildlife Refuge (NWR/refuge) ESTABLISHING AND ACQUISITION AUTHORITIES: Havasu NWR, originally known as Havasu Lake NWR, was established by Executive Order 8647 on January 22, 1941, by President Franklin Roosevelt. REFUGE PURPOSE(S): For lands acquired under Executive Order 8647 "...as a refuge and breeding grounds for migratory birds and other wildlife...” For lands acquired under the Refuge Recreation Act “...suitable for (1) incidental fish and wildlife-oriented recreational development, (2) the protection of natural resources, (3) the conservation of endangered species or threatened species..." For lands acquired under the Fish and Wildlife Conservation Act "...for the development, advancement, management, conservation, and protection of fish and wildlife resources...for the benefit of the United States Fish and Wildlife Service [Service], in performing its activities and services. Such acceptance may be subject to the terms of any restrictive or affirmative covenant, or condition of servitude...” Additional lands totaling 2,757 acres were subsequently added on February 11, 1949, per Public Land Order 559. The purpose of these additional acres was the same as the purpose set out in Executive Order 8647. The Lower Colorado River Land Use Plan (USDOI 1964) describes the high wildlife values of Topock Marsh, Topock Gorge, and the Bill Williams River. The document describes their “prime wildlife values” and expresses a need to “improve

  • ATTACHMENT B Dams and Reservoirs Along the Lower
    ATTACHMENTS ATTACHMENT B Dams and Reservoirs Along the Lower Colorado River This attachment to the Colorado River Interim Surplus Criteria DEIS describes the dams and reservoirs on the main stream of the Colorado River from Glen Canyon Dam in Arizona to Morelos Dam along the international boundary with Mexico. The role that each plays in the operation of the Colorado River system is also explained. COLORADO RIVER INTERIM SURPLUS CRITERIA DRAFT ENVIRONMENTAL IMPACT STATEMENT COLORADO RIVER DAMS AND RESERVOIRS Lake Powell to Morelos Dam The following discussion summarizes the dams and reservoirs along the Colorado River from Lake Powell to the Southerly International Boundary (SIB) with Mexico and their specific roles in the operation of the Colorado River. Individual dams serve one or more specific purposes as designated in their federal construction authorizations. Such purposes are, water storage, flood control, river regulation, power generation, and water diversion to Arizona, Nevada, California, and Mexico. The All-American Canal is included in this summary because it conveys some of the water delivered to Mexico and thereby contributes to the river system operation. The dams and reservoirs are listed in the order of their location along the river proceeding downstream from Lake Powell. Their locations are shown on the map attached to the inside of the rear cover of this report. Glen Canyon Dam – Glen Canyon Dam, which formed Lake Powell, is a principal part of the Colorado River Storage Project. It is a concrete arch dam 710 feet high and 1,560 feet wide. The maximum generating discharge capacity is 33,200 cfs which may be augmented by an additional 15,000 cfs through the river outlet works.

  • Lake Havasu City Recommended Landscaping Plant List
    Lake Havasu City Recommended Landscaping Plant List Lake Havasu City Recommended Landscaping Plant List Disclaimer Lake Havasu City has revised the recommended landscaping plant list. This new list consists of plants that can be adapted to desert environments in the Southwestern United States. This list only contains water conscious species classified as having very low, low, and low-medium water use requirements. Species that are classified as having medium or higher water use requirements were not permitted on this list. Such water use classification is determined by the type of plant, its average size, and its water requirements compared to other plants. For example, a large tree may be classified as having low water use requirements if it requires a low amount of water compared to most other large trees. This list is not intended to restrict what plants residents choose to plant in their yards, and this list may include plant species that may not survive or prosper in certain desert microclimates such as those with lower elevations or higher temperatures. In addition, this list is not intended to be a list of the only plants allowed in the region, nor is it intended to be an exhaustive list of all desert-appropriate plants capable of surviving in the region. This list was created with the intention to help residents, businesses, and landscapers make informed decisions on which plants to landscape that are water conscious and appropriate for specific environmental conditions. Lake Havasu City does not require the use of any or all plants found on this list. List Characteristics This list is divided between trees, shrubs, groundcovers, vines, succulents and perennials.

  • West Wide Energy Corridors Draft Programmatic Environmental Impact Statement – Talking Points
    West Wide Energy Corridors Draft Programmatic Environmental Impact Statement – Talking Points The proposed designations in Draft Programmatic EIS (PEIS) will have significant impacts to wildlife habitat, cultural resources, recreation opportunities, and many other resources on federal lands across the west. Once designated, the corridors (averaging 3500 feet wide but ranging up to 5 miles in width) will cover 6,000 miles and almost 3 million acres of public lands. Areas within the designated corridors are essentially deemed appropriate for pipelines and powerlines, with expedited construction applications and limited environmental review. With large-scale buildup likely within these corridors - the PEIS contemplates that about 9 individual 500-kv transmission lines, as many as 35 liquid petroleum pipelines or up to 29 natural gas pipelines could be supported within a single 3,500-foot- wide corridor – public involvement in the planning process is crucial to ensure that the designation of these corridors is a positive step for our public lands. Key points to raise at public meetings include: By taking the responsibility to move forward with a process to designate large swaths of our federal lands as places for oil, gas and hydrogen pipelines and power lines, the government also took on the responsibility of doing it right. Doing it right would involve ensuring that: new pipelines or powerlines are actually needed – agencies should analyze the potential to meet growing energy demands through increased energy efficiency, distributed generation and maximizing the use of the existing power grid through technology upgrades before turning to additional or wider corridors on our public land; federal lands are necessary locations and special or sensitive public lands are avoided altogether – agencies should continue analyzing impacts to special public lands and moving corridors to avoid them.

  • Chapter 3 – Affected Environment
    Glen Canyon Dam Long-Term Experimental and Management Plan October 2016 Final Environmental Impact Statement 3 AFFECTED ENVIRONMENT Chapter 3 describes the environmental resources (physical, biological, cultural, recreational, and socioeconomic) that could be affected by the range of alternatives for implementing the Glen Canyon Dam Long-Term Experimental and Management Plan (LTEMP), as described in Chapters 1 and 2. The extent to which each specific resource may be affected by each alternative is discussed in Chapter 4, Environmental Consequences.1 3.1 PROJECT AREA The project area includes the area potentially affected by implementation of the LTEMP (including normal management and experimental operations of Glen Canyon Dam and non-flow actions). This area includes Lake Powell, Glen Canyon Dam, and the river downstream to Lake Mead (Figure 3.1-1). More specifically, the scope primarily encompasses the Colorado River Ecosystem, which includes the Colorado River mainstream corridor and interacting resources in associated riparian and terrace zones, located primarily from the forebay of Glen Canyon Dam to the western boundary of Grand Canyon National Park (GCNP). It includes the area where dam operations impact physical, biological, recreational, cultural, and other resources. This section of the river runs through Glen, Marble, and Grand Canyons in Coconino and Mohave Counties in northwestern Arizona. Although this EIS focuses primarily on the Colorado River Ecosystem, the affected area varies by resources and extends outside of the immediate river corridor for some resources and cumulative impacts. Portions of Glen Canyon National Recreation Area (GCNRA), GCNP, and Lake Mead National Recreation Area (LMNRA) outside the Colorado River Ecosystem are also included in the affected region for certain resources due to the potential effects of LTEMP operations.

  • Top Lakes to Visit in Arizona
    Top Lakes to Visit in Arizona Written by Leslie K. Hughes Any water seen in Phoenix for the next few months can either be attributed to monsoons or mirages. In order to quench your thirst for more consistent and tangible enjoyment of water, escape the Valley and head to one of Arizona’s refreshing lakes. The Grand Canyon state has a number of notable lakes hidden within its deserts; here are the most notable ones: MORMON LAKE Holding the title of Arizona’s biggest natural lake, Mormon Lake is a must-see. Southeast of Flagstaff, this lake provides a multitude of activities; from racing speedboats, to surfing, to fishing, Mormon Lake does not leave its visitors disappointed. Be aware, however, that during droughts the lake can dry up entirely, so be sure to check the notices on the website below before heading up North. You may even be lucky enough to catch sight of some buffalo while up there! Mormon Lake Lodge offers log cabin stays, or campgrounds for those more adventurous travelers. Make sure to grab a drink at the lodge’s 1880s-style saloon where you can give your two-step skills a whirl Friday and Saturday nights with live music performances. http://www.fs.usda.gov/coconino/ and http://www.mormonlakelodge.com/ LAKE PLEASANT On the border of Maricopa and Yavapai counties, Lake Pleasant is the go-to spot for a quick escape from the Valley heat. The lake was created by the Waddell Dam’s diversion of water from the Colorado River, and its clear blue water attracts outdoor enthusiasts from all over.
