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. For more information on BPA's role at Lake Roosevelt and throughout the region, call the BPA Public Involvement Office toll-free from Washington, Idaho and Montana at 1-800-547-6048, or from Oregon at 1-800-452-8429.
