Summary
The earth dam stands at a height of 28 feet with a length of 350 feet, creating a storage capacity of 95 acre-feet. It is state-regulated by the Iowa DNR and is inspected, permitted, and enforced by the state, ensuring its safety and compliance with regulations.
The dam, situated on TR-Bacon Creek, has a low hazard potential and a moderate risk assessment rating. While it lacks certain features like outlet gates and spillway width, its condition is currently rated as "Not Rated." Despite this, Ludvigson Dam remains an important structure for water resource management in Woodbury County, Iowa, providing essential services for fire protection and agriculture. As a private-owned dam, it plays a crucial role in the local ecosystem and water supply.
Although Ludvigson Dam has not undergone recent inspections or condition assessments, its risk management measures and emergency action plans are not available. With a limited surface area of 7 acres and a drainage area of 0.45 square miles, the dam continues to serve its primary purposes effectively. As a significant part of the local water infrastructure, Ludvigson Dam represents a key feature in regulating water resources and enhancing environmental sustainability in the region.

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.
