The U. S. Army Corps Engineers operates and manages some 250 locks and dams in major rivers and ports throughout the U. S. At present, many of these structures are thirty-five to forty-five years old or older, well into their planned fifty-year life span, and in need of rehabilitation. This paper presents a set of procedures for the identification of critical components of locks and dams, surveys an array of available corrective actions, and suggests a step-by-step approach to the documentation of risk-benefit analysis in rehabilitation.
