Centralia, located in Port Edwards, Wisconsin, is a historic hydroelectric dam on the Wisconsin River with a gravity design that was completed in 1887. The dam stands at 30 feet tall with a hydraulic height of 15.5 feet and a structural height of 30 feet, providing a normal storage capacity of 1950 acre-feet and serving multiple purposes including hydroelectric power generation and recreation. With a low hazard potential and a very high risk assessment rating, Centralia is regulated by the Federal Energy Regulatory Commission and undergoes inspections every three years to ensure its structural integrity and safety.

The dam features a controlled spillway with a width of 870 feet and is equipped with 13 Tainter radial gates for water flow control. Despite its age, the dam's condition assessment is currently listed as not available, highlighting the need for ongoing monitoring and maintenance to mitigate any potential risks associated with its operation. With its rich history, significant role in water resource management, and picturesque location on the Wisconsin River, Centralia serves as a focal point for water resource and climate enthusiasts interested in the intersection of historic infrastructure and environmental sustainability in the region.

Overall, Centralia represents a blend of engineering ingenuity, natural beauty, and regulatory oversight, making it a key landmark in the water management landscape of Wisconsin. As communities continue to grapple with the impacts of climate change on water resources, the importance of maintaining and safeguarding structures like Centralia becomes increasingly vital to ensure the continued resilience of water infrastructure in the face of evolving environmental challenges. With its unique design, historical significance, and critical role in power generation and recreation, Centralia stands as a testament to the enduring legacy of water resource management in the region.
