Inundation ZoneLake Orange Picture for Website

Some residents in Orange County have properties that are located within the Lake Orange Dam "inundation zone." The "inundation zone" is the area downstream of the dam that would be flooded in the event of a failure (breach) or uncontrolled release of water. These zones are generally much larger than the area for the normal river or stream flood event. The inundation zone maps for Lake Orange can be viewed and downloaded at link below.

Updates & Inspections

The dam is owned and maintained by Orange County and is inspected regularly to ensure its safety. The Orange County Planning and Emergency Services departments have updated the Lake Orange Emergency Action Plan, which includes maps and evacuation routes for affected areas, in the highly unlikely event of a breach or failure.
