Considering the Residual Risk from Dams in Flood Risk Products (Dam Safety Fact Sheet 2 of 4)

This fact sheet addresses the residual risk from dams as represented in flood risk products. It explains how dam outlet control structures affect downstream flow rates and highlights that residual risks remain even when dams operate as intended. The document uses examples such as Hurricane Harvey and Hurricane Matthew to illustrate risks from overtopping and breach. It emphasizes the need to consider dams in flood risk assessments and mapping for accurate representation of upstream and downstream hazards.
