Schramms, also known as Seeley Lake, is a privately owned dam located in Sauk County, Wisconsin. Built in 1850, this rockfill structure stands at a height of 11 feet and spans 170 feet in length, creating a reservoir with a storage capacity of 180 acre-feet. The dam serves primarily for recreational purposes, offering a surface area of 49.4 acres for activities such as fishing, boating, and wildlife observation.

Despite its age, Schramms has a fair condition assessment and a low hazard potential, indicating that it is currently stable and poses minimal risk to downstream areas. The dam is under state regulation by the Wisconsin Department of Natural Resources, with regular inspections and enforcement measures in place to ensure its safety and compliance with regulatory standards. In the event of an emergency, the dam has an uncontrolled spillway with a width of 160 feet to manage excess water flow.

In conclusion, Schramms is a historic dam with a moderate risk assessment rating due to its age and potential for hazards. However, with proper maintenance and oversight, this structure continues to provide valuable recreational opportunities for the community while operating within regulatory guidelines to ensure public safety and environmental protection.
