Ripon, also known as Gothic Mill Pond, is a local government-owned water resource located in Fond du Lac, Wisconsin. Managed by the Wisconsin Department of Natural Resources, Ripon serves primarily for recreational purposes and was completed in 1860. The earth dam, standing at 10 feet tall with a hydraulic height of 8 feet, spans a length of 300 feet and has a storage capacity of 180 acre-feet.

With a spillway width of 45 feet and a maximum discharge of 720 cubic feet per second, Ripon poses a significant hazard potential, prompting inspections every three years. Despite being classified as very high risk, the condition assessment of the dam is deemed satisfactory as per the latest inspection in January 2020. The dam's location on Silver Creek and its controlled spillway design add to its unique features, attracting water resource and climate enthusiasts to explore its historical significance and engineering marvel.
