As the number of new dam projects dropped during the late 1980's, the focus shifted from construction to operation of dams in Norway. In this process, the importance of emergency warning and monitoring of long-term behaviour was realized and resulted in a guideline for monitoring and instrumentation in 1996. After 7 years, the guideline has been revised and this paper summaries the content of the revised guideline [NVE, 2003]. Some Norwegian dams have a dam break warning system and a brief history of this system is also described.
