Summary

Completed in 1849, this dam stands at 25 feet high and has a storage capacity of 600 acre-feet. With a surface area of 61 acres and a drainage area of 47 square miles, the dam serves as a popular spot for outdoor activities in the area.

Managed by the Wisconsin Department of Natural Resources (WIDNR), Oxford Dam has been inspected regularly to ensure its safety and structural integrity. With a low hazard potential and a satisfactory condition assessment, the dam poses minimal risk to the surrounding community. Despite its age, the dam has undergone modifications in 1932 and 1999, showcasing its adaptability to changing needs and regulations.

With Glenn Grothman as the representative for the area, Oxford Dam remains a key feature in the local landscape, providing not only recreational opportunities but also serving as a testament to the region's historical and environmental significance. Climate and water resource enthusiasts can appreciate the balance between preservation and functionality that Oxford Dam represents in the context of Wisconsin's natural beauty.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
