The importance of free longitudinal passage of river fauna is stressed.

This history explores the story of federal contributions to dam planning, design, and construction by carefully selecting those dams and river systems that seem particularly critical to the story. The history also addresses some of the negative environmental consequences of dam-building, a series of problems that today both Reclamation and the U.S. Army Corps of Engineers seek to resolve.

Focusing on reservoir sedimentation management and control, this work defines the nature and severity of sedimentation, reviews relevant physical processes, describes techniques used to combat sedimentation, and presents detailed case studies.
