Summary

This structure, with a height of 8 feet and a hydraulic height of 2.6 feet, serves as a habitat for aquatic life while also providing recreational opportunities for visitors. The dam, primarily made of earth and stone, spans a length of 640 feet and has a storage capacity of 896.6 acre-feet, with a normal storage level of 310 acre-feet.

Despite being classified as having a low hazard potential, the Baraboo River Wrp is assessed to be in fair condition as of May 2020. Its moderate risk level is being managed through undisclosed risk management measures. The structure has not been modified in recent years, and inspections are conducted every 10 years to ensure its safety and functionality. The dam features an uncontrolled spillway with a width of 47 feet, allowing excess water to safely exit the pond during high flow events. Overall, the Baraboo River Wrp plays a vital role in supporting local wildlife and maintaining the ecological balance of the Baraboo River tributary.

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.
