This book was written by members of the SAICE History and Heritage Un (three of whom were on-site during construction of the project) to commemorate 50 years since the completion of the Gariep Dam. It describes in terms understandable by non-engineers, how the scheme evolved, how the dams, tunnels, and canals were built, how this bold project affected the country at the time, and how its benefits are being reaped today. It is a great record of achievement by civil engineers and a great South African success story.
