The CRI is designed to address the legal, scientific, and political issues related to water use from the mainstem of the Columbia River in Washington State. The economic analysis in this report is one of several kinds of information that will be used to inform the Department of Ecology’s rule- making related to the Columbia River. In addition to this review, the State has contracted with the National Academy of Sciences to consider the relationship between water use and the health of salmon populations. This report focuses on the economic consequences of increased water diversions in the mainstem Columbia river in Washington State, including effects on agricultural production, municipal and industrial water supplies, hydropower generation, flood control, river navigation, commercial and recreational fishing, regional impacts, and passive use values. In addition to gauging these effects, the report includes a summary of issues related to the increased use of market transactions in water rights. The analysis is focused on a series of five “Management Scenarios” developed by the Department of Ecology in consultation with water users.

Statements of significance describe why an area is important within a global, national, regional, and systemwide context. These statements are linked to the purpose of the park unit, and are supported by data, research, and consensus. Significance statements describe the distinctive nature of the park and inform management decisions, focusing efforts on preserving and protecting the most important resources and values of the park unit. • Lake Roosevelt National Recreation Area, which includes some of the most publicly accessible shoreline in the Pacific Northwest, offers a wide range of visitor experiences and appropriate recreational opportunities. • Lake Roosevelt National Recreation Area is located within two distinct geologic provinces—the Okanogan Highlands and the Columbia Plateau—and is an outstanding and easily accessible landscape sculpted by a rare combination of sequential geologic processes: volcanism, collision of tectonic plates, continental glaciation, and cataclysmic ice age floods. • Lake Roosevelt National Recreation Area is located at a historic convergence point for numerous Pacific Northwest tribes and contains a central gathering place in their traditional homeland, including the site of the second-largest The purpose of LAKE ROOSEVELT NATIONAL prehistoric and historic Native American fishery on the RECREATION AREA is to protect, conserve, Columbia River.

The eleven western states, those west of the iooth meridian, including Arizona, New Mexico, Utah, Nevada, California, Wyoming, Colorado, Montana, Idaho, Oregon and Washington, are the home of somewhat more than 9% of the population of the United States, but they contain only 4.5% of the farmed and cropped area. These eleven states can never be agriculturally self-sustaining. Their towering mountain ranges, the plateaus and sweeps of sagebrush wastes and deserts, the vast stands of forest timber leave only 54,- 300,000 acres of the states' total land area of 760,400,000 acres that can be cultivated. This is only slightly larger than the State of Nebraska. Of this arable area of 54,300,000 acres, nearly one-half, or about 24,000,000 acres, is non-irrigable.

  • Wvter Action
    WVTER TO ACTION GRAND COULEE DAM AND LAKE ROOSEVELT U.S. BUREAU OF RECLAMATION- BONNEVILLE POWER ADMINISTRATION -U.S. NATIONAL PARK SERVICE ake Roosevelt has steadily gained in popularity as a summer tourist attraction. t High reservoir levels most years provide visitors with a rich variety of recreational opportunities. But many people are not aware of the full story behind Grand Coulee Dam and the great lake it created. This brochure explains the origin of Lake Roosevelt, why it was built and how it serves the people of the Pacific Northwest. It represents a unified effort on the part of the three federal agencies most involved in management and oversight of Lake Roosevelt and Grand Coulee Dam: the U. S. Bureau of Reclamation, the Bonneville Power Administration, and the U.S. National Park Service. Who's responsible for what? The U.S. Bureau of Reclamation built and operates the Columbia Basin Project including Grand Coulee Dam. While many parties with diverse needs and interests provide input in the pro­ ject's operation, Reclamation makes the final decisions. To contact a repre­ sentative of Reclamation, call (509) 638-1360 or write to Grand Coulee Project Office, Attention: Code 140, Grand Coulee, Washington 99133. The Bonneville Power Administration markets and distributes power gener­ ated at federal dams on the Columbia River and its tributaries. In 1980, a new federal law charged BPA with ensuring that the Northwest has an adequate sup­ ply of power, whether from hydroelectric dams or other generating resources. BPA schedules power generation at Grand Coulee Dam within constraints established by Reclamation that provide for the project's multipurpose benefits.

Both the No Action and Action Alternatives include four potential operational scenarios that could occur annually within their respective ranges, depending upon the hydrology of any given year. Both alternatives include refilling the reservoir to elevation 1570 feet by September 22. The No Action Alternative is the preferred alternative. The draft environmental impact statement provided Reclamation’s determination that the Action Alternative “may affect but is not likely to adversely affect” the federally listed bald eagle (Haliaeetus leucocephalus) and would have no effect on the federally listed pygmy rabbit (Brachylagus idahoensis) or Ute ladies’-tresses (Spiranthes diluvialis).

In 1941 the federal government dammed the Columbia River at the north endof Grand Coulee, creating a man-made reservoir named Lake Roosevelt that inundated homes, farms, and businesses, and disrupted the lives ofmany. Although Congress never enacted specific authorization to createa park, it passed generic legislation that gave the Park Service authorityat the National Recreation Area (NRA). Lake Roosevelt's shoreline totalsmore than 500 miles of cliffs and gentle slopes. The Lake Roosevelt NationalRecreation Area (LARO) was officially created in 1946. This historical study documents
