Frequently Asked Questions
What is overtopping?
Watch video explanation:Overtopping occurs when water flows over the top of a dam. This is dangerous and may cause the dam to fail, especially if it wasn’t designed for that level of overflow.
Why do we need to maintain dams?
Watch video explanation:Regular maintenance ensures dams perform safely and reliably. Without proper maintenance, dams can erode, weaken, or become unsafe for nearby communities.
What is hazard creep?
Watch video explanation:Hazard creep happens when new development downstream from a dam increases the risk to life or property. A dam originally classified as “low hazard” can be reclassified if homes or businesses are built within its potential flood zone.
