Completed in 1964, this earth dam stands at a height of 224 feet and stretches 4410 feet in length. Its primary purpose is flood risk reduction, but it also serves other functions such as fish and wildlife pond, recreation, and water supply. The dam's storage capacity, spillway type, and hazard potential are all key factors in assessing its risk management strategies.
Despite reducing flood risk to downstream communities, Canyon Lake Dam - Dike A still presents a high hazard potential, primarily due to the possibility of overtopping during extreme flood events. The risk assessment conducted in May 2020 characterized the risk as moderate, emphasizing the potential consequences of a dike breach leading to downstream flooding. To manage this risk, the US Army Corps of Engineers implements measures such as updating emergency action plans, conducting regular inspections, and collaborating with local emergency managers to enhance evacuation procedures and response capabilities.
Continuous efforts are made to mitigate the risk associated with Canyon Lake Dam - Dike A, including stockpiling materials, maintaining road surfaces for erosion resistance, and closely monitoring the structure's performance. Despite well-practiced emergency action plans and collaboration with local authorities, the potential for dike failure and subsequent flooding remains a concern, highlighting the importance of ongoing risk management and preparedness efforts by the US Army Corps of Engineers.
