Oregon participates in such regional accords as the Columbia River Compact (between Oregon and Washington on fishing), Columbia River Gorge Compact, Columbia River Boundary Compact, Klamath River Compact (with California), Pacific States Marine Fisheries Commission, Pacific Ocean Resources Compact, Northwest Power and Conservation Council (with Idaho, Montana, and Washington), and several western groups concerned with corrections, education, and energy matters.
While Oregon receives federal assistance for a variety of programs, federal involvement is particularly heavy in the areas of energy and natural resources, through federal development, operation, and marketing of hydroelectric power and federal ownership of forest and grazing lands. Approximately 49% of Oregon's land area is owned by the federal government. Federal grants to Oregon totaled more than $4.3 billion in 2001.
