This concrete gravity dam serves multiple purposes, including hydroelectric power generation, navigation, recreation, and water supply. With a structural height of 15 feet and a hydraulic height of 10 feet, the dam has a spillway width of 593 feet and a controlled spillway type.
A recent risk assessment conducted in 2021 classified the dam as having a very high risk potential, with identified risk factors including seepage under the earth embankment and scour downstream of the concrete dam that could impact power generation and flow regulation. To mitigate these risks, USACE and other partners continuously monitor and maintain the dam, with regular inspections and emergency action plans in place. In 2011, the dam's gates were replaced and concrete piers rehabilitated to enhance the structure's reliability and long-term resilience.
Overall, Cedars Lock and Dam plays a crucial role in managing water resources and mitigating flood risks in the region. Through proactive risk management measures and ongoing maintenance efforts, the dam continues to ensure the safety and functionality of the water infrastructure while supporting various economic and recreational activities along the Fox River.
