1 Columbia River Component Site Conceptual Model and Data Gap Analysis

2 The Columbia River Arguably the most significant environmental force in the Pacific Northwest region of the United States. -The Center for Columbia River History

3 The Idaho Compass Copyright © 2004 Thousands of years ago, Native Americans inhabited the region we define as Washington and Oregon today. George Chute Copyright © Oregon Public Broadcasting The Indian tribes of the Pacific Northwest coast and the Columbia River have always relied on salmon as major food source, a foundation for life, culture, economy, and spirituality. Fishing continues today along the Columbia River using traditional and more modern methods.

4 11 major dams on the main stem, and hundreds of major and modest structures on tributaries block river flows and tap a large portion of the Columbia's generating capacity: More than 21 million kilowatts. -The Center for Columbia River History

5 The 40 foot-deep channel in the lower river allows ocean freighters navigation up the Columbia to Portland and barges can transport goods to the interior. -The Center for Columbia River History

6 The river has provided irrigation to many local farms which grow alfalfa, potatoes, mint, beets, beans, orchard fruit, and wine grapes. -The Center for Columbia River History

7 Six percent of the river basin’s yearly runoff is diverted to irrigate about 7.8 million acres of land.

10 Columbia River Activity Pre – development, pre – 1880s Native Americans have lived along the Columbia River, from the mouth of the Snake River all the way to the Pacific Ocean, for thousands of years and countless generations. It is an area rich in natural resources. Game was plentiful and wild plant foods, such as camas and wapato, were harvested in season. Photo courtesy of Nez Perce National Historical Park, Stephen D. Shawley Collection. But it was the river itself, and its tributaries, that yielded the greatest bounty.
