Summary

The dam stands at a height of 11 feet and has a hydraulic height of 5 feet, providing a storage capacity of 54 acre-feet with a maximum discharge of 3,492 cubic feet per second. The dam, with a length of 150 feet and a spillway width of 125 feet, poses a significant hazard potential and is classified as having a moderate risk level.

Managed by the Wisconsin Department of Natural Resources, the Newburg dam is under state regulation with permitting, inspection, and enforcement in place to ensure its safety and compliance with guidelines. The dam is located within the Congressional District 05 of Wisconsin and is surrounded by a serene environment that offers opportunities for recreation and enjoyment. Despite its age and historical significance, the dam's condition assessment is currently listed as "Not Rated", indicating a need for further evaluation and potential risk management measures to be implemented in the future.

Water resource and climate enthusiasts visiting Newburg can explore the dam's construction and learn about its impact on the surrounding area's water management and environmental conservation efforts. With its unique design and purposeful existence, the Newburg dam serves as a reminder of the importance of sustainable water resource management and the need for ongoing monitoring and maintenance to ensure the safety of both the structure and the community it serves. As a focal point for outdoor activities and recreational enjoyment, the dam contributes to the local economy and provides a picturesque setting for visitors to appreciate the beauty of the natural landscape.

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.
