Revisiting projects of historic importance with respect to the development of modern design and construction practice can provide valuable insights and reminders of methods and alternatives available to engineers for current and future projects. Empirical methods continue to be employed in the geotechnical engineering of dams, as engineers it is our responsibility to understand the development of these methods so we can better understand their applicability and limitations. Knowledge of the methods used by pioneers in the field such as Prof. Casagrande can also be applied to the challenges we face today. 9 ACKNOWLEDGEMENTS This research was funded by the Natural Sciences and Engineering Research Council of Canada (NSERC) Canadian Dam Association * Summer 2016 Discovery Grants Program and the Research Institute on Mines and Environment UQAT/Polytechnique (www.irme.ca).
