Database Presentation





The World Register of Dams is a database of more than 62,000 dams. Two-thirds of them are currently georeferenced.


The World Register of Dams is an essential source of information for design, construction, scientific work and statistical assessments. It gives references on large dams (as defined by ICOLD) around the world. It is one of the pillars of the international dam community and a showcase for the general public. It is of great importance both for the ICOLD and for all those involved in the field.


The Committee responsible for the Register coordinates the centralization of the data provided by ICOLD National Committees. It also incorporates data on dams in countries that are not members of ICOLD. From the year 2023, the register included dams in 166 countries. All the information collected is integrated into the database, after formatting by the Committee of the Register. New versions are posted on a regular basis, roughly on an annual basis.


The data concerns characteristics specific to the dams (year of commissioning, height, length, type, etc.), characteristics relating to the associated reservoirs (volume of the reservoir, area of the reservoir, purposes, etc.), data on the stakeholders (owners, design offices, contractors, etc.) and elements relating to geography (country, river concerned, locality). Since September 2023, the coordinates of the dam expressed by the longitude and latitude of the WGS84 geodetic system are also available when known. All of these elements are provided by the ICOLD National Committees or are extracted from publicly accessible databases or websites.


While every effort is made to avoid data errors, ICOLD cannot guarantee the accuracy of each value or provide missing data. ICOLD, the ICOLD Central Office, the National Committees and the members of the Committee of the Register cannot be held responsible for any errors or omissions that may have occurred.


On the ICOLD website, the database is assisted by a search engine, the operation of which is explained in this document.


The use of the data is the responsibility of the end user. When using the data, in particular in the form of publications, the user is required to indicate their origin by specifying the mention "ICOLD/CIGB – World Register of Dams/Registre Mondial des Barrages – xxx" or xxx represents the version date of the database (indicated at the top of the search engine page).


ICOLD warmly thanks the members of the committee, the ICOLD General Secretariat, all the responsible persons in the National Committees and those who participated in the data collection.

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.”
