Glen Canyon Dam Long-Term Experimental and Management Plan EIS

About Us

The Bureau of Reclamation and National Park Service have prepared the LTEMP DEIS with assistance from Argonne National Laboratory and the U.S. Geological Survey.

About the Bureau of Reclamation

Established in 1902, the Bureau of Reclamation (Reclamation) is best known for the dams, powerplants, and canals it constructed in the 17 western states. These water projects led to homesteading and promoted the economic development of the West. Today, these facilities bring water to more than 31 million people, and provide Western farmers with irrigation water for 10 million acres of farmland that produce 60% of the nation's vegetables and 25% of its fruits and nuts.

Reclamation is also the second-largest producer of hydroelectric power in the western United States. Reclamation's 58 powerplants annually provide more than 40 billion kilowatt hours, generating nearly a billion dollars in power revenues and producing enough electricity to serve 3.5 million homes. Reclamation operates Glen Canyon Dam. With a total capacity of 1,320 megawatts, Glen Canyon Dam Powerplant produces around 4.5 billion kilowatt-hours of hydroelectric power annually, which helps supply the electrical needs of about 5.8 million customers.

The mission of the Bureau of Reclamation is to manage, develop, and protect water and related resources in an environmentally and economically sound manner in the interest of the American public.

About the National Park Service

The National Park Service (NPS) manages the 395 units of the National Park System. The NPS also helps administer dozens of affiliated sites, the National Register of Historic Places, National Heritage Areas, National Wild and Scenic Rivers, National Historic Landmarks, the National Seashores, and National Trails. The fundamental purpose of the NPS is to conserve the scenery and the natural and historic objects and the wildlife therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.

The National Park System includes more than 84 million acres and is comprised of 395 areas called "units." The units include 123 historical parks or sites, 74 monuments, 58 national parks, 25 battlefields or military parks, 18 preserves, 18 recreation areas, 10 seashores, 4 parkways, 4 lakeshores, and 2 reserves. Grand Canyon National Park, Glen Canyon National Recreation Area, and Lake Mead National Recreation Area are units of the National Park System.

About Argonne National Laboratory

Argonne National Laboratory is one of the U.S. Department of Energy's largest research centers. It is also the nation's first national laboratory, chartered in 1946. The Environmental Science Division (EVS) of Argonne National Laboratory conducts basic and applied research and assessment that seek to understand how natural and human-managed environmental systems function and how system components respond to various perturbations. EVS studies the environmental effects of conventional and renewable energy development and use. EVS focuses on five major program areas: (1) land and renewable resources; (2) ecological resources and systems; (3) radiation and chemical risk management; (4) environmental security and restoration; and (5) atmospheric science and climate research. In addition to these program areas, the Center for Geospatial Analysis brings together over 20 EVS staff and other Argonne researchers who specialize in geographic information systems (GIS), spatial modeling, remote sensing, geospatial statistics, visualization, data management, software development, and cartography.

About the U.S. Geological Survey

The U.S. Geological Survey (USGS) is a science organization within the Department of Interior that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.

The USGS serves the Nation by providing reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.

The USGS employs experts who bring a range of earth and life science disciplines to bear on problems. By integrating their diverse scientific expertise, the USGS is able to understand complex natural science phenomena and provide scientific products that lead to solutions.

As the Nation's largest water, earth, and biological science and civilian mapping agency, the USGS collects, monitors, analyzes, and provides scientific understanding about natural resource conditions, issues, and problems. The diversity of the USGS scientific expertise enables the organization to carry out large-scale, multi-disciplinary investigations and provide impartial scientific information to resource managers, planners, and other customers.
