Downstream Hazard Assessments for Small Dams

• The “standard of care” nationwide is to know what happens below
  your dam should it fail. If your dam is over 50 acre feet in capacity,
  you should apply for a downstream hazard classification. What if
  your dam is under 50 acre feet? You still should know what hazards
  are at risk below your dam. It is possible to estimate the dam breach
  flood area using a few simplifying assumptions and making some basic
  calculations. For information and guidance, please refer to the Small
  Dam Hazard Assessment Inventory.
