Rodolf, also known as Balmoral, is a gravity dam located in Richland, Wisconsin, along the Mill Creek. Built in 1840 for hydroelectric purposes, Rodolf stands at a structural height of 21.3 feet and a hydraulic height of 15 feet. With a dam length of 200 feet and a maximum discharge capacity of 3650 cubic feet per second, the dam has a storage capacity of 500 acre-feet and covers a surface area of 42 acres.

Managed by the local government and regulated by the Wisconsin Department of Natural Resources, Rodolf is primarily used for hydroelectric power generation and recreation. Despite being classified as having a low hazard potential, the dam underwent modifications in 1922. The last inspection in September 2009 deemed Rodolf's condition as not rated, with an inspection frequency of 10 years and a moderate risk rating of 3. The dam's emergency action plan and risk management measures are currently not specified.

For water resource and climate enthusiasts, Rodolf serves as a historical and functional structure that contributes to the local energy production and recreational activities. With its picturesque location in Richland, Wisconsin, the dam's role in harnessing hydroelectric power while maintaining a moderate risk level highlights the importance of ongoing monitoring and maintenance to ensure its long-term sustainability and safety.
