According to the Association of State Dam Safety Officials (ASDSO), the five most likely causes of dam failures are: overtopping, foundation defects, cracking, inadequate maintenance and upkeep, and piping.[1] In order to prevent a dam failure, a properly designed foundation is essential.

“The earth embankment and its foundation must be stable and withstand all anticipated loads without movements leading to failure. Provide measures for adequate seepage control under all anticipated loads.” [2]
