In the heart of Green Lake County, Wisconsin, lies the picturesque town of Manchester, home to a charming dam on the Grand River that dates back to 1914. This gravity dam stands at 16 feet in height and spans 250 feet in length, providing not only recreational opportunities but also hydroelectric power. With a storage capacity of 140 acre-feet and a normal storage level of 50 acre-feet, the dam serves as a vital resource for the community.

Managed by the Wisconsin Department of Natural Resources, the Manchester dam has a low hazard potential and a moderate risk assessment rating. While the dam's condition assessment is currently not rated, it undergoes inspections every 10 years to ensure its structural integrity and safety. The dam's spillway, of the uncontrolled type, allows for a maximum discharge of 1085 cubic feet per second, providing protection against potential overflow events.

For water resource and climate enthusiasts, Manchester's dam on the Grand River is not only a historical landmark but also a key piece of infrastructure that plays a crucial role in water management and recreational activities in the area. Its gravity design and concrete construction highlight the town's commitment to sustainable water resource management, making Manchester a must-visit destination for those interested in the intersection of water conservation, hydroelectric power, and community resilience.
