COURSE ENVR 327W: WATER RESOURCES HIGHLIGHTS
SYLLABUS
The course takes a systems approach to examining the water resources of the U.S. West. Emphasis is placed on evaluating water resources from a variety of scales and perspectives, using the Colorado, Klamath and Columbia river basins as case studies.
ENROLLMENT
This writing-centered course enrolls about 20 students from across disciplines, although they are expected to have background knowledge about human and earth systems. Several students have been inspired by the course to go into careers related to water resources. INSTRUCTOR
Karen Arabas, professor of environmental sciences, has been teaching this course since she arrived at Willamette almost 20 years ago. An East Coast native, she became fascinated as a graduate student at George Washington University by the complex story of Western water issues. Today, even her students from arid parts of the West, who are familiar with water conservation needs, are surprised to discover the complicated, interwoven natures of these crucial issues.

Throughout the course, students work within a systems framework. This holistic approach views the Earth’s natural components, such as atmosphere, hydrosphere and biosphere, as interacting within one unified system. Human society is layered on top of — and affects — these natural systems and processes. To clearly observe the interactions, students create elaborately charted and color-coded diagrams that show the flows of water between and within natural and human systems. They study each river in detail to see how the natural and human systems interact, and soon learn that each one has unique features — and problems. The 257-mile Klamath River is an “upside-down basin” that starts in a flat agricultural area in south-central Oregon and travels through remote canyons to the ocean in California. As the river is a prime habitat for salmon, steelhead and rainbow trout, fishing rights for Native Americans are a key issue — and heated conflicts have arisen with local farmers who demand access to the water to irrigate their crops. In fact, about 80 percent of water in the West goes to agricultural use. The 1,243-mile Columbia River, the largest river in the Pacific Northwest, originates in Canada and empties into the Pacific Ocean at the border between Washington and Oregon. With 14 hydroelectric dams on the main river, notes Arabas, “the Columbia has powered the development of the Pacific Northwest.” In particular, the cheap hydroelectricity supported the Hanford Site, a nuclear production complex established in southeastern Washington in 1943. Radioactive material was released into the river before site decommissioning began in the late 1980s, and future contamination of the Columbia by leftover waste remains a concern. The final river studied, the 1,450mile Colorado River, starts high in the
