Database Presentation



The World Register of Dams is a database including more than 58 000 dams.


The Committee of the Register coordinates the data collection within the National Committees. It also includes data on dams in non-member countries of the CIGB. They are included in the database, after validation by the Committee of the Register.

On the website, the database is served by a powerful search engine, which is described in this document.

The International Commission on Large Dams


The International Commission On Large Dams (ICOLD) is a non-governmental International Organization which provides a forum for the exchange of knowledge and experience in dam engineering.


The Organization leads the profession in ensuring that dams are built safely, efficiently, economically, and without detrimental effects on the environment. Its original aim was to encourage advances in the planning, design, construction, operation, and maintenance of large dams and their associated civil works, by collecting and disseminating relevant information and by studying related technical questions.


Since the late sixties, focus was put on subjects of current concern such as dam safety, monitoring of performance, reanalysis of older dams and spillways, effects of ageing and environmental impact. More recently, new subjects include cost studies at the planning and construction stages, harnessing international rivers, information for the public at large, and financing.

Laos Dam failure

 Press Release


Dam Failure in Laos



The International Commission on Large Dams (ICOLD) is following the situation very closely as information is just coming out about the collapse of the saddle dam at the Xe Pian Xe Namnoy Hydroelectric Dam, in Laos.




ICOLD newly elected President Michael Rogers made the following statement:


“Our deepest condolences go out to the people of Laos impacted by this tragedy, especially those families who have lost loved ones and/or their homes.


Dams are critical pieces of not only physical, but also socio-economic infrastructure that supply renewable power, storage for agricultural, industrial, municipal and community water supply. Like other large infrastructure in our societies, dams provide critical service, but also pose high risks that must be addressed during the planning, design and construction phases.   The precautionary principle of dams to prevent and/or mitigate adverse downstream safety consequences informs and is at the heart of the ICOLD Mission.


ICOLD has been working for 90 years to promote the safe and sustainable design and construction of dams.  As an organization of 100 nations committed to the safety of all dams around the world, ICOLD stands ready to assist and support the project owner and the national dam safety organization in Laos to assess the situation and work towards recovery.  Moving forward, it will be important to understand the full cause of this apparent failure so that important lessons may be shared with other nations and dam owners. This is the heart of ICOLD mission and the main reason why it was founded.  For example, during its recent Congress in Vienna (July 1-7 2018), ICOLD organized an important open workshop on the lessons learned from the Oroville Spillway Incident (USA, 2017).


Again, our heartfelt condolences go out to the thousands of persons downstream of this dam that have been impacted by this tragedy and ICOLD stands ready to support Laos in any way possible.”
