Drainage area of the dam, in square miles, which is defined as the area that drains to a particular point (in this case, the dam) on a river or stream.
Dams assigned the low hazard potential classification are those where failure or misoperation results in no probable loss of human life and low economic and/or environ-mental losses. Losses are principally limited to the ownerâs property.
An emergency action plan is defined as a plan of action to be taken to reduce the potential for property damage and loss of life in an area affected by a dam failure or large flood.
