Summary
Owned privately, the dam serves multiple purposes including fire protection, stock maintenance, and small fish pond creation. It has a storage capacity of 70 acre-feet and a surface area of 5.2 acres, making it a crucial water resource for the area.
Maintained and regulated by the Iowa Department of Natural Resources, Stutzman Dam has been deemed to have a low hazard potential with a moderate risk assessment. The dam is primarily of earth type construction with a soil foundation, providing stability and longevity for the structure. Despite its low hazard potential, the dam's safety and effectiveness in water resource management are regularly inspected and monitored by state agencies to ensure its continued functionality for the community.
For water resource and climate enthusiasts, Stutzman Dam serves as a notable example of private ownership and state regulation working together to provide essential water management solutions. With its diverse purposes and moderate risk assessment, the dam showcases the importance of proper infrastructure maintenance and oversight in ensuring the safety and sustainability of water resources 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.
