Walla Walla District History: Part II: 1970-1975
During the period from 1970 to 1975 the Walla Walla District of the U.S.. Army Corps of Engineers constructed locks and dams on the Snake River, completing the final segment of a 465-mile seaway from the Pacific Ocean to Lewiston, Idaho. In 1973 the 717-foot-high Dworshak Dam on the North Fork Clearwater River in Idaho was dedicated. These multipurpose projects added to the nation's electrical energy resources and provided benefits in flood control, recreation3 and wildlife habitat. Such achievements were not met with universal approval3 however. Environmentalists and others were concerned with the effect of the dams on water quality fisheries and wildlife habitat. The District became increasingly involved in preparing environmental assessments of projects past and future. It was a time of adjustment, change, and challenge. In this second volume author Howard Preston has captured the flavor and tempo of a half decade in the District's 27-year history when construction efforts peaked and operational aspects of completed projects moved into prominence.
