Part of: Water Management in the '90s: A Time for Innovation


Development of the Columbia River basin has had a profound impact on its natural resources, particularly species of Pacific Salmon. Passage of the Northwest Power Act of 1980 put in motion an unprecedented regional effort to restore the natural resources of the basin as affected by development of the hydroelectric system. Provisions of the act are compelling an interdisciplinary approach to hydrosystem planning and operations, as well as natural resource management. Symptomatic of this has been the development and use of computer modeling to assist regional decision making. This paper will discuss biological modeling in the Columbia basin and the role of modeling in restoration of large ecosystems.
