The Lower Snake River Project received the outstanding water resources engineering project award for 1976 from ASCE. The lower 140-mile (225-km) reach of the Snake River from its mouth to the Idaho line has been developed with four dams: Ice Harbor, Lower Monumental, Little Goose, and Lower Granite. Reliable water transportation for towboat and barge is a reality now, reaching from the Pacific Ocean upstream on the Columbia and Snake Rivers for 465 miles (748-km) to Lewiston, Idaho. The unique features associated with development of the multipurpose project, the Lower Snake River Project, exemplify sound engineering decisions for some of the most complex structural, hydraulic, environmental, and geotechnical engineering problems.
