The annual ICOLD event is the venue for meetings of Technical Committees that are at the heart of the organization’s mission. The meetings are open to all delegates to the Symposium or Congress. ICOLD Technical Committees publish Bulletins on various topics of interest to dam owners, engineers and scientists. CDA members participate on many ICOLD committees. The Technical Bulletins are available free for download by CDA members. ICOLD also offers Bulletins in hard-copy and on CD for sale through its website.

During the development of ICOLD Bulletins, draft ICOLD Bulletins are issued for review and comment by the National Committees (CDA is the |National Committee for Canada). They are posted on the CDA members-only International Committee page. 

CDA’s participation in ICOLD is coordinated by an elected Director at Large, who chairs the CDA International Committee. If you are interested in helping provide a Canadian perspective on an ICOLD Technical Committee, please email the Director at Large – ICOLD

ICOLD was founded in 1928 and has National Committees from over 100 countries. ICOLD provides a forum for the exchange of knowledge and experience in dam engineering. ICOLD’s mission is to lead the profession in setting standards and guidelines to ensure that dams are built and operated safely, efficiently, economically and are environmentally sustainable and socially equitable.
