This is not intended to be a design guide. Rather, this guide highlights past experiences and lessons learned from others.

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.
