Smallpox Creek Dam, also known as Lake Galena, is a privately owned recreational dam located in Jo Daviess, Illinois. Built in 1974 by Bauer Engineering Inc., this rockfill dam stands at 60 feet high and stretches 1100 feet long, creating a reservoir with a storage capacity of 6500 acre-feet. The dam sits on Smallpox Creek and is regulated by the Illinois Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.

With a high hazard potential and a moderate risk assessment rating of 3, Smallpox Creek Dam is closely monitored for any potential safety issues. Its spillway is uncontrolled with a width of 273 feet, and the dam does not feature any outlet gates or associated locks. Despite its remote location, the dam poses a risk to downstream areas in the event of a breach or failure. Emergency action plans were last revised in 1990, showcasing the need for updated measures to mitigate risks and ensure the safety of surrounding communities.

For water resource and climate enthusiasts, Smallpox Creek Dam serves as a significant recreational structure in Illinois, offering opportunities for water-based activities and wildlife habitat. However, its aging infrastructure and high hazard potential highlight the importance of ongoing monitoring and maintenance to prevent any potential threats to public safety and the environment. As climate change impacts continue to affect water resources, the resilience and safety of dams like Smallpox Creek become increasingly vital for sustainable water management and community protection.
