Dixon, located in Lee County, Illinois, is home to a Rockfill dam on Rock Creek that was completed in 1924 for hydroelectric and recreational purposes. Managed by a public utility, the dam stands at 16 feet in height with a spillway width of 610 feet. With a normal storage capacity of 2576 acre-feet and a drainage area of 8655 square miles, the dam plays a significant role in water resource management in the area.

The Federal Energy Regulatory Commission oversees the regulatory aspects of the dam's operation, including inspections and enforcement. Despite being classified as having a low hazard potential, the dam is deemed to have a moderate risk level. The emergency action plan for the dam was last revised in December 2019, and regular inspections are conducted to ensure its safety and integrity. Dixon's dam serves as a vital piece of infrastructure for both energy production and recreational activities in the region.

With its historical significance dating back almost a century, the Dixon dam continues to be a key player in water resource management in Illinois. As climate change impacts water availability and usage patterns, the importance of sustainable water management practices in the region cannot be overstated. The collaboration between state and federal agencies ensures the continued safe operation of the dam, while also emphasizing the need for proactive risk assessment and management strategies to address potential challenges in the future.
