Summary
Built in 1963 by the USDA NRCS, this earth dam stands at 23 feet high and spans 582 feet in length, with a storage capacity of 57 acre-feet. The dam is situated along TR Vance Creek Offstream, within the jurisdiction of the Wisconsin Department of Natural Resources (WIDNR).
Despite its low hazard potential, Nordby's condition assessment is rated as poor, signaling a need for maintenance and potential upgrades to ensure its continued safety and functionality. The last inspection in 2010 revealed issues that have persisted, highlighting the importance of regular monitoring and upkeep to mitigate risks. With a very high risk assessment score of 1, there is a pressing need for improved risk management measures and potentially the development of an Emergency Action Plan (EAP) to enhance preparedness in case of emergencies.
For water resource and climate enthusiasts, Nordby presents an intriguing case study of a multi-purpose dam facing challenges in maintenance and risk management. Its location in a high-risk area underscores the importance of proactive measures to safeguard its integrity and surrounding community. As efforts to address its poor condition and mitigate risks continue, Nordby serves as a reminder of the critical role that infrastructure plays in water resource management and the need for sustainable practices in the face of changing environmental conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
