Report to the World Commission on Dams - Cape Town, South Africa. Revised Draft (May 4, 2000).

This report presents preliminary results of an international survey of ex post evaluations of water projects, programs and policies related to large dams. The survey was inspired by Professor Gilbert F. White's repeated calls for post audits, and his criticisms that few comprehensive studies have been undertaken to date. We are grateful to Professor White for his encouragement and comments on an earlier draft.
