ABSTRACT:

Bonneville Lock and Dam is a large run-of-the-river navigation improvements and hydropower project located 40 miles east of Portland, OR. The project was constructed by the US Army Corps of Engineers between 1934 and 1938 and subsequently modified with expansion of the first powerhouse in 1941, completion of a second powerhouse in 1981 and a larger replacement navigation lock in 1991. Smaller project modifications continues on Bonneville to the present day. This presentation focuses on the role and importance of geology in the design, construction and operation of the project.
