Summary

Completed in 1971, the dam serves multiple purposes, including fire protection, stock watering, and small fish pond management. With a structural height of 28 feet and a length of 340 feet, Haldeman has a storage capacity of 16 acre-feet and covers a surface area of 1 acre, draining a 0.6 square mile watershed.

Despite being classified as having a low hazard potential, Haldeman is regularly inspected by the Wisconsin Department of Natural Resources, with the most recent assessment in March 2021 indicating a fair condition. The dam features an uncontrolled spillway and a maximum discharge capacity of 120 cubic feet per second. While the risk assessment is moderate, with a rating of 3 out of 5, there are currently no documented emergency action plans in place for the structure.

Overall, Haldeman serves as a vital water resource in the region, contributing to fire protection and ecosystem management. As climate change continues to impact water availability and quality, it is crucial to maintain and monitor structures like Haldeman to ensure their long-term functionality and safety for both human and environmental well-being.

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.
